PRELIMINARY PROSPECTUS
Subject to Completion dated July 11, 2011

$300,000,000
Offer to Exchange

8.875% Senior Notes due 2019,

which have been registered under the Securities Act of 1933,

for any and all outstanding

8.875% Senior Notes due 2019,

which have not been registered under the Securities Act of 1933,

EarthLink, Inc.

•: We will exchange all original notes that are validly tendered and not withdrawn before the end of the exchange offer for an equal principal amount of new notes that we have registered under the Securities Act of 1933.
•: This exchange offer expires at 11:59 p.m., New York City time, on , 2011, unless extended.
•: No public market exists for the original notes or the new notes. We do not intend to list the new notes on any securities exchange or to seek approval for quotation through any automated quotation system.
•: Each broker-dealer that receives new notes for its own account pursuant to the exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of such new notes.
•: A broker-dealer who acquired original notes as a result of market-making or other trading activities may use this prospectus, as supplemented or amended from time to time, in connection with resale of the new notes.

See "Risk Factors" beginning on page 19 for a discussion of the risks that holders should consider prior to making a decision to exchange original notes for new notes.

The notes are our senior unsecured obligations, rank equally in right of payment with all of our existing and future senior indebtedness (including our existing 3.25% convertible senior notes) and rank senior to all of our future indebtedness that is subordinated in right of payment to the notes. Each of our existing and future domestic subsidiaries (other than (i) ITC^DeltaCom, Inc. and its subsidiaries and (ii) certain other excluded subsidiaries) have unconditionally guaranteed the notes with guarantees that are unsecured and rank equally in right of payment with all of the senior indebtedness of such guarantor and rank senior to all of the future indebtedness of such guarantor that is subordinated in right of payment to the guarantee of such guarantor. The notes and the guarantees are effectively subordinated to all of our and the guarantors' existing and future secured indebtedness, including amounts outstanding under our new senior secured revolving credit facility, to the extent of the value of the assets securing such indebtedness and are structurally subordinated to all obligations of our subsidiaries that do not guarantee the notes, including ITC^DeltaCom, Inc. and its subsidiaries.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The date of this prospectus is , 2011.

FORWARD-LOOKING STATEMENTS

Certain statements contained or incorporated by reference in this prospectus are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933, and Section 21E of the Securities Exchange Act of 1934. The words "estimate," "plan," "intend," "expect," "anticipate," "believe" and similar expressions are intended to identify forward-looking statements. These forward-looking statements are found at various places throughout this prospectus and the documents incorporated by reference in this prospectus and are subject to risks and uncertainties that could cause actual results to differ materially from those described. Although we believe that the expectations expressed in these forward-looking statements are reasonable, we cannot promise that our expectations will turn out to be correct. Our actual results could be materially different from and worse than our expectations. We disclaim any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

Important factors that could cause actual results to differ from estimates or projections contained in the forward-looking statements include, without limitation (1) that we may not be able to execute our business strategy to transition to a leading IP infrastructure and managed services provider, which could adversely impact our results of operations and cash flows; (2) that we may be unsuccessful in making and integrating acquisitions into our business, which could result in operating difficulties, losses and other adverse consequences; (3) that the effects of adverse economic conditions could harm our business; (4) that if we do not continue to innovate and provide products and services that are useful to individual subscribers and business customers, we may not remain competitive, and our revenues and operating results could suffer; (5) that our failure to implement cost reduction initiatives will adversely affect our results of operations; (6) that we will require a significant amount of cash, which may not be available to us, to service our debt and fund our other liquidity needs; (7) that we face significant competition in the Internet industry that could reduce our profitability; (8) that our consumer business is dependent on the availability of third-party network service providers; (9) that the continued decline of our consumer access subscribers, combined with the change in mix of our consumer access base from narrowband to broadband, will adversely affect our results of operations; (10) that our commercial and alliance arrangements may not be renewed or may not generate expected benefits, which could adversely affect our results of operations; (11) that privacy concerns relating to our business could damage our reputation and deter current and potential users from using our services; (12) that changes in technology in the Internet access industry could cause a decline in our business; (13) that we face significant competition in the communications industry that could reduce our profitability; (14) that decisions by the Federal Communications Commission relieving ILECs (incumbent local exchange carrier, which term includes former Bell Systems or other independent telephony companies responsible for providing local telephone exchange services in a specified geographic area) of certain regulatory requirements, and possible further deregulation in the future, may restrict our ability to provide services and may increase the costs we incur to provide these services; (15) that our wholesale services, including our broadband transport services, will be adversely affected by pricing pressure, network overcapacity, service cancellations and other factors; (16) that our financial performance will suffer if we are not offered competitive rates for the access services we need to provide our long distance services; (17) that we may experience reductions in switched access and reciprocal compensation revenue; (18) that our inability to maintain and upgrade our network infrastructure, portions of which we do not own, could adversely affect our operating results; (19) that if we are unable to interconnect with AT&T, Verizon and other incumbent carriers on acceptable terms, our ability to offer competitively priced local telephone services will be adversely affected; (20) that we may not be able to compete effectively if we are unable to install additional network equipment or convert our network to more advanced technology; (21) that failure to obtain and maintain necessary permits and rights-of-way could interfere with our network infrastructure and operations; (22) that we may be unable to retain sufficient qualified personnel, and the loss of any of our key executive officers could adversely affect us;

Table of Contents

(23) that interruption or failure of our network and information systems and other technologies could impair our ability to provide our services, which could damage our reputation and harm our operating results; (24) that our business depends on effective business support systems and processes; (25) that government regulations could adversely affect our business or force us to change our business practices; (26) that our business may suffer if third parties used for customer service and technical support and certain billing services are unable to provide these services or terminate their relationships with us; (27) that we may not be able to protect our intellectual property; (28) that we may be accused of infringing upon the intellectual property rights of third parties, which is costly to defend and could limit our ability to use certain technologies in the future; (29) that if we, or other industry participants, are unable to successfully defend against legal actions, we could face substantial liabilities or suffer harm to our financial and operational prospects; (30) that we may be required to recognize additional impairment charges on our goodwill and intangible assets, which would adversely affect our results of operations and financial position; (31) that we may have to undertake further restructuring plans that would require additional charges, including incurring facility exit and restructuring charges; (32) that we may have exposure to greater than anticipated tax liabilities and the use of our net operating losses and certain other tax attributes could be limited in the future; (33) that we may reduce, or cease payment of, quarterly cash dividends; (34) that our stock price may be volatile; (35) that our indebtedness could adversely affect our financial health and limit our ability to react to changes in our industry; and (36) that provisions of our second restated certificate of incorporation, amended and restated bylaws and other elements of our capital structure could limit our share price and delay a change of management. These risks and uncertainties are described in greater detail in the section of the prospectus captioned "Risk Factors" and in the information included in our annual report on Form 10-K for the fiscal year ended December 31, 2010 in the "Risk Factors" section therein, which section is incorporated herein by reference.

Our Company

EarthLink, Inc.

EarthLink, Inc., together with its consolidated subsidiaries, provides a comprehensive suite of communications services to individual and business customers. We operate two reportable segments, Business Services and Consumer Services. Our Business Services segment provides integrated communications and related value-added services to businesses, enterprise organizations and communications carriers. These services include data services, including managed IP-based network services and high-speed, or broadband, Internet access and voice services, including local exchange, long-distance and conference calling; mobile data and voice services; and web hosting. Our Business Services segment also sells transmission capacity to other communications providers on a wholesale basis. Our Consumer Services segment provides nationwide Internet access and related value-added services to individual customers. These services include dial-up and high-speed Internet access services, ancillary services sold as add-on features to our Internet access services, search and advertising. We provide our business services primarily through a nationwide network utilizing a 27-state fiber optic network, Multi-Protocol Label Switching ("MPLS") and other technologies. We provide our consumer services primarily through third-party telecommunications service providers.

Our corporate offices are located at 1375 Peachtree St., Atlanta, Georgia 30309, and our telephone number at that location is (404) 815-0770. Our website is located athttp://www.earthlink.net. None of the information that appears on or is linked to or from our website is incorporated by reference into or is otherwise made a part of this prospectus.

Business Strategy

Successfully integrate and realize the potential of synergistic acquisitions. Our Business Services segment has been strengthened through the acquisition of fiber network assets, strengthening our ability to provide nationwide customers with an enhanced service platform, offering voice, data, video and managed services. We are focused on successfully integrating ITC^DeltaCom, One Communications and STS Telecom, LLC, or "STS", with our existing operations and expect to realize cost synergies, as well as increase the scale and scope of our product offerings. We believe that our strategic and

Table of Contents

competitive positioning will be strengthened by our ability to continue to successfully integrate these and other potential acquisitions.

Enhance our position as a leading IP infrastructure and managed services provider. Through the combination of our existing business services with the integrated communications businesses of our recent acquisitions, ITC^DeltaCom, One Communications and STS, we offer a comprehensive suite of business services under a new brand, EarthLink Business. We believe that our combined sales force and service offerings will be attractive to multi-location business customers and helpful in promoting brand awareness and achieving operating synergies and revenue growth. We believe that to continue to enhance our ability to offer these services supports our long-term strategic direction and will further our objectives of strengthening our competitive position, expanding our customer base, providing greater scale to accelerate innovation and increasing stockholder value.

Optimize our Consumer Services segment operations. We remain focused on retaining our customers and building long-term customer relationships based on customized service offerings and superior customer service. We believe focusing on the customer relationship increases loyalty and reduces churn. We continue to focus on offering our services with high-quality customer service and technical support. We also intend to continue to use cash generated from our Consumer Services segment operations to fund growth under our acquisition strategy in our Business Services segment. We also continue to seek to add consumer customers that generate an acceptable rate of return, including through alliances, partnerships and acquisitions from other ISPs.

Maintain focus on operational efficiency. Our operating framework includes a disciplined focus on operational efficiency. In our Consumer Services segment, we intend to continue to improve the cost structure of our business, without impacting the quality of services we provide. In our Business Services segment, we intend to use this disciplined focus on operational efficiency to create synergies from our recent and potential future acquisitions. We also plan to continue to implement cost reduction initiatives and to manage our business more efficiently.

Selectively pursue potential strategic acquisitions. In addition to the acquisitions of ITC^DeltaCom, One Communications and STS, we will continue to selectively evaluate and consider other potential strategic transactions that we believe will complement and grow our business. Our acquisition strategy may include investment in additional network depth in geographic areas that further expand our recently acquired fiber network, investment in new product and services capabilities and the acquisition of business customers within our network to create more scale. The nationwide reach and depth of our network will allow us to leverage any newly acquired product and service capabilities to all of our customers with lower incremental cost.

The primary challenges we face in executing our business strategy for our Business Services segment are continuing to develop new profitable managed services offerings that will be attractive to multi-location customers, successfully integrating our acquisitions to achieve expected synergies and cost savings, responding to competitive and economic pressures in the communications industry and adapting to regulatory changes and initiatives. The primary challenges we face in executing our Consumer Services segment are managing the rate of decline in our consumer revenues, implementing outsourcing and other cost-saving initiatives, and operating our network cost-effectively, including network services purchased from third-party telecommunications service providers. The factors we believe are instrumental to the achievement of our business strategy may be subject to competitive, regulatory and other events and circumstances that are beyond our control. Further, we can provide no assurance that we will be successful in achieving any or all of the strategies identified above, that the achievement or existence of such strategies will favorably impact profitability, or that other factors will not arise that would adversely affect future profitability.

The Exchange Offer


The Exchange Offer		We are offering to exchange up to $300,000,000 aggregate principal amount of our new 8.875% Senior Notes due 2019 (the "new notes") for up to $300,000,000 aggregate principal amount of our original 8.875% Senior Notes due 2019 (the "original notes"), which are currently outstanding. Original notes may only be exchanged in a minimum principal amount of $2,000 and $1,000 principal increments above such minimum. In order to be exchanged, an original note must be properly tendered and accepted. All original notes that are validly tendered and not validly withdrawn prior to the expiration of the exchange offer will be exchanged.
Resales Without Further Registration		Based on interpretations by the staff of the Securities and Exchange Commission ("SEC") in several no action letters issued to third parties, we believe that the new notes issued pursuant to the exchange offer may be offered for resale, resold or otherwise transferred by you without compliance with the registration and prospectus delivery provisions of the Securities Act of 1933, as amended (the "Securities Act") provided that:
		• you are acquiring the new notes issued in the exchange offer in the ordinary course of your business;
		• you have not engaged in, do not intend to engage in, and have no arrangement or understanding with any person to participate in, the distribution of the new notes issued to you in the exchange offer in violation of the provisions of the Securities Act; and
		• you are not our "affiliate," as defined under Rule 405 of the Securities Act.
		Each broker-dealer that receives new notes for its own account in exchange for original notes, where such original notes were acquired by such broker-dealer as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of such new notes.

Table of Contents


		The letter of transmittal states that, by so acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of new notes received in exchange for original notes where such original notes were acquired by such broker-dealer as a result of market-making activities or other trading activities. We have agreed to use our reasonable best efforts to make this prospectus, as amended or supplemented, available to any broker-dealer for a period of 180 days after the date of this prospectus for use in connection with any such resale. See "Plan of Distribution."
Expiration Date		11:59 p.m., New York City time, on , 2011, unless we extend the exchange offer.
Accrued Interest on the New Notes and Original Notes		The new notes will bear interest from May 17, 2011 or the last interest payment date on which interest was paid on the original notes surrendered in exchange therefor. Holders of original notes that are accepted for exchange will be deemed to have waived the right to receive any payment in respect of interest on such original notes accrued to the date of issuance of the new notes.
Conditions to the Exchange Offer		The exchange offer is subject to certain customary conditions which we may waive. See "The Exchange Offer—Conditions."
Procedures for Tendering Original Notes		Each holder of original notes wishing to accept the exchange offer must complete, sign and date the letter of transmittal, or a facsimile of the letter of transmittal; or if the original notes are tendered in accordance with the book-entry procedures described in this prospectus, the tendering holder must transmit an agent's message to the exchange agent at the address listed in this prospectus. You must mail or otherwise deliver the required documentation together with the original notes to the exchange agent.

Table of Contents


Special Procedures for Beneficial Holders		If you beneficially own original notes registered in the name of a broker, dealer, commercial bank, trust company or other nominee and you wish to tender your original notes in the exchange offer, you should contact such registered holder promptly and instruct them to tender on your behalf. If you wish to tender on your own behalf, you must, before completing and executing the letter of transmittal for the exchange offer and delivering your original notes, either arrange to have your original notes registered in your name or obtain a properly completed bond power from the registered holder. The transfer of registered ownership may take considerable time.
Guaranteed Delivery Procedures		You must comply with the applicable guaranteed delivery procedures for tendering if you wish to tender your original notes and:
		• your original notes are not immediately available; or
		• time will not permit your required documents to reach the exchange agent prior to 11:59 p.m., New York City time, on the expiration date of the exchange offer; or
		• you cannot complete the procedures for delivery by book-entry transfer prior to 11:59 p.m., New York City time, on the expiration date of the exchange offer.
Withdrawal Rights		You may withdraw your tender of original notes at any time prior to 11:59 p.m., New York City time, on the date the exchange offer expires.
Failure to Exchange Will Affect You Adversely		If you are eligible to participate in the exchange offer and you do not tender your original notes, you will not have further exchange or registration rights and your original notes will continue to be subject to restrictions on transfer under the Securities Act. Accordingly, the liquidity of the original notes will be adversely affected.
Certain U.S. Federal Income Tax Consequences		The exchange of original notes for new notes pursuant to the exchange offer will not result in a taxable event. Accordingly, we believe that:
		• no gain or loss will be realized by a United States holder upon receipt of a new note;
		• holder's holding period for the new notes will include the holding period of the original notes; and
		• the adjusted tax basis of the new notes will be the same as the adjusted tax basis of the original notes exchanged at the time of such exchange.
		See "Certain U.S. Federal Income Tax Considerations."

Summary of Terms of New Notes

The exchange offer constitutes an offer to exchange up to $300,000,000 aggregate principal amount of the new notes for up to an equal aggregate principal amount of the original notes. The new notes will be obligations of EarthLink evidencing the same indebtedness as the original notes, and will be entitled to the benefit of the same indenture. The form and terms of the new notes are substantially the same as the form and terms of the original notes except that the new notes have been registered under the Securities Act. See "Description of the Notes."

Comparison with Original Notes


Freely Transferable		The new notes will be freely transferable under the Securities Act by holders who are not restricted holders. Restricted holders are restricted from transferring the new notes without compliance with the registration and prospectus delivery requirements of the Securities Act. The new notes will be identical in all material respects (including interest rate, maturity and restrictive covenants) to the original notes, with the exception that the new notes will be registered under the Securities Act. See "The Exchange Offer—Terms of the Exchange Offer."
Registration Rights		The holders of the original notes currently are entitled to certain registration rights pursuant to the registration rights agreement entered into on the issue date of the original notes by and among EarthLink, the subsidiary guarantors named therein and the initial purchasers named therein, including the right to cause EarthLink to register the original notes for resale under the Securities Act if the Exchange Offer is not consummated prior to the time so required pursuant to the registration rights agreement. However, pursuant to the registration rights agreement, such registration rights will expire upon consummation of the exchange offer. Accordingly, holders of original notes who do not exchange their original notes for new notes in the exchange offer will not be able to reoffer, resell or otherwise dispose of their original notes unless such original notes are subsequently registered under the Securities Act or unless an exemption from the registration requirements of the Securities Act is available.
Terms of New Notes
Issuer		EarthLink, Inc.
Notes Offered		The form and terms of the new notes will be the same as the form and terms of the outstanding notes except that:
		• the new notes will bear a different CUSIP number from the original notes;
		• the new notes have been registered under the Securities Act and, therefore, will not bear legends restricting their transfer; and

Table of Contents


		• you will not be entitled to any exchange or registration rights with respect to the new notes.
		The notes will evidence the same debt as the original notes. They will be entitled to the benefits of the indenture and the supplemental indentures governing the original notes and will be treated under the indenture and the applicable supplemental indentures as a single class with the original notes. We refer to the new notes and the original notes collectively as the notes in this prospectus.
Maturity Date		May 15, 2019.
Interest		The notes will bear interest at a rate of 8.875% per annum from May 17, 2011. Interest on the notes will be payable semi-annually in cash on May 15 and November 15 of each year, commencing on November 15, 2011.
Guarantees		Each of our existing and future domestic subsidiaries (other than (i) ITC^DeltaCom and its subsidiaries and (ii) certain other excluded subsidiaries) will unconditionally guarantee the notes on the issue date on a senior unsecured basis.
Ranking		The notes:
		• will be general senior unsecured obligations of the Issuer;
		• will rank equally in right of payment with all existing and future senior indebtedness of the Issuer (including our existing 3.25% convertible senior notes), but will be effectively subordinated to all of the Issuer's existing and future secured indebtedness to the extent of the value of the collateral that secures such indebtedness;
		• will be senior in right of payment to all existing and future Indebtedness of the Issuer that is subordinated in right of payment to the notes; and
		• will be structurally subordinated to any existing and future indebtedness and other liabilities of subsidiaries of the Issuer that are not guarantors.
		The guarantee of each guarantor:
		• will be a general senior unsecured obligation of such guarantor;
		• will rank equally in right of payment with all existing and future senior indebtedness of such guarantor, but will be effectively subordinated to all of such guarantor's secured indebtedness to the extent of the value of the collateral that secures such indebtedness;
		• will be senior in right of payment to all existing and future indebtedness of such guarantor that is subordinated in right of payment to its guarantee; and

Table of Contents


		• will be structurally subordinated to any existing and future indebtedness and other liabilities of subsidiaries of such guarantor that is not also a guarantor.
		As of March 31, 2011, after giving pro forma effect to the offering of the original notes, the use of the net offering proceeds from the notes offering, the consummation of the acquisition of One Communications and our entry into our $150 million senior secured revolving credit facility:
		• the Issuer and our subsidiaries would have had $659.2 million of indebtedness outstanding, of which approximately $369.2 million would have been senior secured indebtedness;
		• the Issuer would have had an additional $150.0 million of unutilized capacity under our senior secured revolving credit facility; and
		• the Issuer's subsidiaries that are not guarantors would have had $458.4 million of indebtedness and other liabilities outstanding.
		On a pro forma basis after giving effect to the offering of the original notes, the use of the net offering proceeds from the notes offering and the consummation of the acquisitions of ITC^DeltaCom and One Communications, the Issuer's subsidiaries that are not guarantors would have accounted for approximately:
		• $441.4 million (or 28%) of the Issuer's consolidated revenues and $24.3 million (or 32%) of the Issuer's consolidated net loss, in each case for the fiscal year ended December 31, 2010; and
		• $625.8 million (or 36%) of the Issuer's consolidated total assets and $441.2 million (or 46%) of the Issuer's consolidated total liabilities, in each case as of December 31, 2010.
		• the Issuer and our subsidiaries would have had $659.2 million of indebtedness outstanding, of which approximately $369.2 million would have been senior secured indebtedness;
		• the Issuer would have had an additional $150.0 million of unutilized capacity under our senior secured revolving credit facility; and
		• the Issuer's subsidiaries that are not guarantors would have had $458.4 million of indebtedness and other liabilities outstanding.

Optional Redemption		We may redeem the notes, in whole or in part, at any time on or after May 15, 2015 at the redemption prices specified under "Description of Notes—Optional Redemption." Prior to May 15, 2015, we may also redeem the notes, in whole or in part, at a price equal to 100% of the aggregate principal amount of the notes to be redeemed plus a make-whole premium and accrued interest.
Optional Redemption after Certain Equity Offerings		In addition, at any time (which may be more than once) prior to May 15, 2014, we may redeem up to 35% of the aggregate principal amount of the notes with the net cash proceeds of certain equity offerings, so long as:
		• we pay 108.875% of the face amount of the notes, plus accrued and unpaid interest to the redemption date;
		• we redeem the notes within 90 days of completing such equity offering; and
		• at least 65% of the principal amount of the notes remains outstanding afterwards.
Certain Covenants		The indenture and related supplemental indentures governing the notes contain covenants limiting, among other things, our ability and the ability of our restricted subsidiaries to:
		• pay dividends or make certain other restricted payments or investments;
		• incur or guarantee additional indebtedness or issue disqualified stock;
		• create liens;
		• transfer and sell assets;
		• merge, consolidate, or sell, transfer or otherwise dispose of all or substantially all of our assets;
		• enter into certain transactions with affiliates;
		• issue or sell stock of subsidiaries;
		• engage in sale-leaseback transactions; and
		• create restrictions on dividends or other payments by our restricted subsidiaries.
		These covenants are subject to a number of important limitations and exceptions. See "Description of Notes—Certain Covenants."
Change of Control		If a change in control of the Company occurs, we must give holders of the notes the opportunity to sell us their notes at 101% of their face amount, plus accrued interest.

Table of Contents


		We might not be able to pay you the required price for notes you present to us at the time of a change of control, because we might not have enough funds at that time, or the terms of the senior secured revolving credit facility may prevent us from paying.
		See "Risk Factors—Risks Related to the Notes—Upon a change of control, we may not have the ability to raise the funds necessary to finance the change of control offer required by the indenture governing the notes, which would violate the terms of the notes."
Asset Sale Proceeds		If we or our subsidiaries engage in asset sales, we generally must either invest the net cash proceeds from such sales in our business or a related business within a period of time, prepay secured debt or make an offer to purchase a principal amount of the notes equal to the excess net cash proceeds. The purchase price of the notes will be 100% of their principal amount, plus accrued interest.
No Listing on any Securities Exchange		We do not intend to list the new notes on any securities exchange or to seek approval for quotation through any automated system.
Risk Factors		You should carefully consider the information under "Risk Factors" beginning on page 19 of this prospectus and all other information included or incorporated by reference in this prospectus prior to making a decision to exchange original notes for new notes.

For additional information regarding the notes, see the "Description of the Notes" section of this prospectus.

(1): On December 8, 2010, we acquired ITC^DeltaCom, a provider of integrated communications services to customers in the southeastern U.S. The results of operations of ITC^DeltaCom have been included in our consolidated financial statements since the acquisition date.
(2): Operating costs and expenses for the years ended December 31, 2008, 2009 and 2010 include non-cash impairment charges of $78.7 million, $24.1 million, and $1.7 million, respectively, related to goodwill and certain intangible assets of New Edge in our Business Services segment. During 2008 and 2009, we concluded the carrying value of these assets was impaired in conjunction with our annual tests of goodwill and intangible assets deemed to have indefinite lives. During 2010, we decided to re-brand the New Edge name as EarthLink Business and wrote off our New Edge trade name.
(3): Operating costs and expenses for the years ended December 31, 2008, 2009 and 2010 and the three months ended March 31, 2010 and 2011 include restructuring and acquisition-related costs of $9.1 million, $5.6 million, $22.4 million, $1.4 million and $4.5 million, respectively.
(4): During the years ended December 31, 2008 and 2009, we recorded income tax benefits in the Statement of Operations of approximately $56.1 million and $198.8 million, respectively, from releases of our valuation allowance related to deferred tax assets. These deferred tax assets related primarily to net operating loss carryforwards which we determined we will more likely than not be able to utilize due to the generation of sufficient taxable income in the future.
(5): In November 2007, management concluded that the municipal wireless broadband operations were no longer consistent with our strategic direction and our board of directors authorized management to pursue the divestiture of our municipal wireless broadband assets. As a result of that decision, we classified the municipal wireless broadband assets as held for sale and presented the municipal wireless broadband operations as discontinued operations during the year ended December 31, 2008. As of December 31, 2008, we had completed the divestiture of our municipal wireless broadband assets.
(6): Includes the carrying amount of the 3.25% convertible senior notes, which was $219.7 million, $232.2 million $243.1 million, $232.8 million and $246.6 million as of December 31, 2008, 2009 and 2010 and March 31, 2010 and 2011, respectively. During November 2006, we issued $258.8 million aggregate principal amount of 3.25% convertible senior notes in a registered offering. The 3.25% convertible senior notes are convertible on October 15, 2011 and upon certain events. We have the option to redeem the 3.25% convertible senior notes, in whole or in part, for cash, on or after November 15, 2011, provided that we have made at least ten semi-annual interest payments. In addition, the holders may require us to purchase all or a portion of the 3.25% convertible senior

notes on each of November 15, 2011, November 15, 2016 and November 15, 2021. During 2009, we began paying quarterly cash dividends on our common stock. This requires an adjustment to the conversion rate for the 3.25% convertible senior notes and opens a conversion period for holders. As a result, the 3.25% convertible senior notes were classified as a current liability in our Consolidated Balance Sheets as of December 31, 2009. On November 15, 2011, holders of the 3.25% convertible senior notes have the right under the governing indenture to require us to repurchase the 3.25% convertible senior notes. As a result, we classified the 3.25% convertible senior notes as a current liability in the Consolidated Balance Sheet as of December 31, 2010 and March 31, 2011.

As of December 31, 2010 and March 31, 2011, long-term debt also includes the carrying amount of ITC^DeltaCom's 10.5% Senior Secured Notes due 2016 ("ITC^DeltaCom notes") assumed in our acquisition of ITC^DeltaCom in December 2010, which was $351.3 million as of December 31, 2010 and $350.0 million as of March 31, 2011. The ITC^DeltaCom notes will mature on April 1, 2016.

ITC^DeltaCom, Inc. Summary Historical Financial Data

The following table presents summary historical financial data of ITC^DeltaCom. The summary historical consolidated statements of operations data for the years ended December 31, 2008, 2009 and 2010 and balance sheet data as of December 31, 2009 and 2010 below have been derived from ITC^DeltaCom's audited consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America, or "GAAP," which are contained in ITC^DeltaCom's annual report on Form 10-K for the fiscal year ended December 31, 2010 (as revised pursuant to ITC^DeltaCom's Current Report on Form 8-K filed on May 5, 2011) and incorporated herein by reference. The summary historical consolidated statements of operations data for the three months ended March 31, 2010 and 2011 and balance sheet data as of March 31, 2011 below have been derived from ITC^DeltaCom's unaudited consolidated financial statements, which are contained in ITC^DeltaCom's quarterly report on Form 10-Q for the fiscal quarter ended March 31, 2011 and incorporated herein by reference, but include, in the opinion of ITC^DeltaCom's management, all adjustments, consisting of normal recurring adjustments and accruals, necessary for the presentation of such data.

On December 8, 2010, ITC^DeltaCom was acquired by EarthLink. The accounting for the acquisition has been "pushed-down" in ITC^DeltaCom's consolidated financial statements. The financial results have been presented separately for the "Predecessor Entity" period, January 1, 2010 through December 7, 2010, and for the "Successor Entity" period, December 8, 2010 through December 31, 2010. To allow comparison of our results, we combined these periods into a year period from January 1, 2010 through December 31, 2010. However, due to adjustments to our assets and liabilities in connection with purchase accounting, results from the Successor Entity and Predecessor Entity combined may not be indicative of our future results. This combination is not a U.S. GAAP measure and it is only provided to allow the reader to more easily compare the results of the operations for the periods presented.

You should read the summary historical financial data set forth below together with the consolidated financial statements and the related notes of ITC^DeltaCom incorporated by reference into this prospectus.

RISK FACTORS

Before you participate in the exchange offer, you should carefully consider the various risks of the investment, including the risks described below, together with all of the other information included or incorporated by reference in this prospectus. If any of these risks actually occurs, our business, financial condition or operating results could be adversely affected. These risks also could materially affect our ability to meet our obligations under the notes. You could lose all or part of your investment in, and the expected return on, the notes.

Risks Related to the Notes and the Exchange

We have a substantial amount of indebtedness which could adversely affect our financial position and prevent us from fulfilling our obligations under the notes.

We currently have, and following this exchange will continue to have, a substantial amount of indebtedness. As of March 31, 2011, as adjusted to give effect to the offering of the original notes (the "notes offering"), the use of the net offering proceeds from the notes offering, consummation of the acquisition of One Communications and our entry into our new senior secured revolving credit facility, we would have had total debt of approximately $658.9 million, consisting of $300.0 million of the notes and $369.2 million of other debt, as well as an additional $150.0 million of unutilized capacity under our senior secured revolving credit facility. We may also incur significant additional indebtedness in the future. Our substantial indebtedness may:

•: make it difficult for us to satisfy our financial obligations, including making scheduled principal and interest payments on the notes and our other indebtedness;
•: limit our ability to borrow additional funds for working capital, capital expenditures, acquisitions or other general business purposes;
•: limit our ability to use our cash flow or obtain additional financing for future working capital, capital expenditures, acquisitions or other general business purposes;
•: require us to use a substantial portion of our cash flow from operations to make debt service payments;
•: limit our flexibility to plan for, or react to, changes in our business and industry;
•: place us at a competitive disadvantage compared to our less leveraged competitors; and
•: increase our vulnerability to the impact of adverse economic and industry conditions.

Despite our current level of indebtedness, we may still be able to incur substantially more indebtedness. This could exacerbate the risks associated with our substantial indebtedness.

We and our subsidiaries may be able to incur substantial additional indebtedness in the future. The terms of the indenture limit, but do not prohibit, us or our subsidiaries from incurring additional indebtedness. If we incur any additional indebtedness that ranks equally with the notes and the guarantees, the holders of that indebtedness will be entitled to share ratably with the holders of the notes and the guarantees in any proceeds distributed in connection with any insolvency, liquidation, reorganization, dissolution or other winding-up of us. This may have the effect of reducing the amount of proceeds paid to you. If new indebtedness is added to our current debt levels, the related risks that we and our subsidiaries now face could intensify.

Table of Contents

Our ability to generate cash depends on many factors beyond our control, and we may not be able to generate the cash required to service our debt.

Our ability to make payments on and refinance our indebtedness, including the notes, and to fund our operations will depend on our ability to generate cash in the future. Our historical financial results have been, and our future financial results are expected to be, subject to substantial fluctuations, and will depend upon general economic conditions and financial, competitive, legislative, regulatory and other factors that are beyond our control. If we are unable to meet our debt service obligations or fund our other liquidity needs, we may need to refinance all or a portion of our debt, including the notes, before maturity, seek additional equity capital, reduce or delay scheduled expansions and capital expenditures or sell material assets or operations. We cannot assure you that we will be able to pay our debt or refinance it on commercially reasonable terms, or at all, or to fund our liquidity needs.

If for any reason we are unable to meet our debt service obligations, we would be in default under the terms of the agreements governing our outstanding debt. If such a default were to occur, the lenders under our senior secured revolving credit facility could elect to declare all amounts outstanding under our senior secured revolving credit facility immediately due and payable, and the lenders would not be obligated to continue to advance funds under our senior secured revolving credit facility. If the amounts outstanding are accelerated, we cannot assure you that our assets will be sufficient to repay in full the money owed to the banks or to our debt holders, including holders of notes.

The indenture governing the notes, our senior secured revolving credit facility and the indenture governing the ITC^DeltaCom notes contain various covenants limiting the discretion of our management in operating our business and could prevent us from capitalizing on business opportunities and taking some corporate actions.

The indenture and the applicable supplemental indentures governing the notes (collectively the "indenture"), our senior secured revolving credit facility and the indenture governing the ITC^DeltaCom notes impose significant operating and financial restrictions on us. These restrictions limit or restrict, among other things, our ability and the ability of our restricted subsidiaries to:

•: incur or guarantee additional indebtedness or issue preferred stock;
•: pay dividends or make other distributions to stockholders;
•: purchase or redeem capital stock or subordinated indebtedness;
•: make investments;
•: create liens or use assets as security;
•: enter into agreements restricting such restricted subsidiaries' ability to pay dividends, make loans or transfer assets to us or other restricted subsidiaries;
•: sell assets, including capital stock of subsidiaries;
•: engage in transactions with affiliates; and
•: consolidate or merge with or into other companies or transfer all or substantially all of our or their assets.

If we default on our obligations to pay our other indebtedness, we may not be able to make payments on the notes.

Any default under the agreements governing our indebtedness, including a default under our senior secured revolving credit facility that is not waived by the required lenders, and the remedies sought by the holders of such indebtedness could prohibit us from making payments of principal, premium, if any, or interest on the notes and could substantially decrease the market value of the

Table of Contents

notes. If we are unable to generate sufficient cash flow and are otherwise unable to obtain funds necessary to meet required payments of principal, premium, if any, or interest on our indebtedness, or if we otherwise fail to comply with the various covenants, including financial and operating covenants, in the instruments governing our indebtedness (including our senior secured revolving credit facility), we could be in default under the terms of the agreements governing such indebtedness. In the event of such default, the holders of such indebtedness could elect to declare all the funds borrowed thereunder to be due and payable, together with accrued and unpaid interest. More specifically, the lenders under our senior secured revolving credit facility could elect to terminate their commitments, cease making further loans and institute foreclosure proceedings against our assets, and we could be forced into bankruptcy, if applicable to us, or liquidation. If our operating performance declines, we may in the future need to seek waivers from the required lenders under the senior secured revolving credit facility to avoid being in default. If we breach covenants under our senior secured revolving credit facility and seek a waiver, we may not be able to obtain a waiver from the required lenders. If this occurs, we would be in default under the revolving credit facility, the lenders could exercise their rights as described above, and we could be forced into bankruptcy, to the extent applicable to us, or liquidation. No assurance can be given that, if we breach covenants under our revolving credit facility and our creditors seek to enforce their rights under the federal bankruptcy laws, that a forum will be available to creditors. See "Description of Certain Indebtedness" and "Description of Notes."

The notes and the guarantees are unsecured and effectively subordinated to our and the guarantors' existing and future secured indebtedness.

The notes and the guarantees are general unsecured obligations ranking effectively junior in right of payment to all of our existing and future secured indebtedness and that of each guarantor, including indebtedness under our senior secured revolving credit facility. Additionally, the indenture governing the notes permits us to incur additional secured indebtedness in the future. In the event that we or a guarantor is declared bankrupt, becomes insolvent or is liquidated or reorganized, any indebtedness that is effectively senior to the notes and the guarantees will be entitled to be paid in full from our assets or the assets of the guarantor, as applicable, securing such indebtedness before any payment may be made with respect to the notes or the affected guarantees. Holders of the notes will participate ratably with all holders of our unsecured indebtedness that is deemed to be of the same class as the notes, and potentially with all of our other general creditors, based upon the respective amounts owed to each holder or creditor, in our remaining assets.

As of March 31, 2011, as adjusted to give effect to the notes offering, the use of the net offering proceeds from the notes offering, the consummation of the acquisition of One Communications and our $150 million senior secured revolving credit facility, the notes and the guarantees would have been effectively subordinated to no senior secured indebtedness under our senior secured revolving credit facility and we would have been able to incur an additional $150 million of indebtedness under our senior secured revolving credit facility on such date, subject to compliance with financial covenants in the senior secured revolving credit facility, all of which would have also been effectively senior to the notes and the guarantees.

Claims of noteholders are structurally subordinated to claims of creditors of our subsidiaries that have not guaranteed the notes.

Not all of our subsidiaries guaranteed the notes. In addition, ITC^DeltaCom, Inc. and its subsidiaries and certain other excluded subsidiaries have not and will not guarantee the notes. Accordingly, claims of holders of the notes are structurally subordinated to the claims of creditors of these non-guarantor subsidiaries, including trade creditors. All obligations of our non-guarantor subsidiaries will have to be satisfied in full before any of the assets of these subsidiaries would be available for distribution, upon a liquidation or otherwise, to us or a guarantor of the notes. Also, the

Table of Contents

guarantees are subject to release under certain circumstances. In any of these events, we may not have sufficient assets to pay amounts due on the notes with respect to the assets of that subsidiary.

On a pro forma basis after giving effect to the notes offering, the use of the net offering proceeds from the notes offering and the consummation of the acquisitions of ITC^DeltaCom and One Communications, our subsidiaries that are not guarantors account for approximately:

•: $441.4 million (or 28%) of the Issuer's consolidated revenues and $24.3 million (or 33%) of the Issuer's consolidated net loss, in each case for the three months ended March 31, 2011; and
•: $625.8 million (or 36%) of the Issuer's consolidated total assets and $441.2 million (or 45%) of the Issuer's consolidated total liabilities, in each case as of March 31, 2011.

The indenture that governs the notes permits us to form a holding company that would be permitted to take actions that may not be consistent with the best interests of the holders of the notes.

The indenture that governs the notes permits us to form a separate holding company that would be the parent company of EarthLink, Inc. and our subsidiaries. If such a holding company were formed, the restrictive covenants contained in the indenture would apply only to EarthLink, Inc. and its subsidiaries and not to the new holding company. As a result, the new holding company could take actions, such as using cash for purposes unrelated to debt service, which may not be consistent with your best interests.

A subsidiary guarantee could be voided if it constitutes a fraudulent transfer under U.S. bankruptcy or similar state law, which would prevent the holders of the notes from relying on that subsidiary to satisfy claims.

Under U.S. bankruptcy law and comparable provisions of state fraudulent transfer laws, a guarantee can be voided, or claims under the guarantee may be subordinated to all other debts of that guarantors if, among other things, the guarantor, at the time it incurred the indebtedness evidenced by its guarantee or, in some states, when payments become due under the guarantee, received less than reasonably equivalent value or fair consideration for the incurrence of the guarantee and:

•: was insolvent or rendered insolvent by reason of such incurrence;
•: was engaged in a business or transaction for which the guarantor's remaining assets constituted unreasonably small capital; or
•: intended to incur, or believed that it would incur, debts beyond its ability to pay those debts as they mature.

A guarantee may also be voided, without regard to these factors, if a court finds that the guarantor entered into the guarantee with the actual intent to hinder, delay or defraud its creditors. A court would likely find that a guarantor did not receive reasonably equivalent value or fair consideration for its guarantee if the guarantor did not substantially benefit directly or indirectly from the issuance of the guarantees. If a court were to void a guarantee, you would no longer have a claim against the guarantor. Sufficient funds to repay the notes may not be available from other sources, including the remaining guarantors, if any. In addition, the court might direct you to repay any amounts that you already received from the subsidiary guarantor.

The measures of insolvency for purposes of fraudulent transfer laws vary depending upon the governing law. Generally, a guarantor would be considered insolvent if:

•: the sum of its debts, including contingent liabilities, were greater than the fair saleable value of all its assets;

Table of Contents

•: the present fair saleable value of its assets is less than the amount that would be required to pay its probable liability on its existing debts, including contingent liabilities, as they become absolute and mature; or
•: it could not pay its debts as they become due.

Each subsidiary guarantee will contain a provision intended to limit the guarantor's liability to the maximum amount that it could incur without causing the incurrence of obligations under its subsidiary guarantee to be a fraudulent transfer. This provision may not be effective to protect the subsidiary guarantees from being voided under fraudulent transfer law. In a recent Florida bankruptcy case, this kind of provision was found to be ineffective to protect the guarantees.

Upon a change of control, we may not have the ability to raise the funds necessary to finance the change of control offer required by the indenture governing the notes, which would violate the terms of the notes.

Upon the occurrence of a change of control, holders of the notes will have the right to require us to purchase all or any part of the notes at a price equal to 101% of the principal amount, plus accrued and unpaid interest, if any, to the date of purchase. We may not have sufficient financial resources available to satisfy all of obligations under the notes in the event of a change in control. Our failure to purchase the notes as required under the indenture would result in a default under the indenture and a cross-default under our senior secured revolving credit facility, each of which could have material adverse consequences for us and the holders of the notes. The holders of our and ITC^DeltaCom's existing notes also have the right to require us to repurchase all of their notes upon the occurrence of certain change of control events. In addition, the senior secured revolving credit facility provides that a change of control is a default that permits lenders to accelerate the maturity of borrowings under it. If such indebtedness is not paid, such lenders may enforce their security interests in the collateral securing the senior secured revolving credit facility and the ITC^DeltaCom notes, thereby limiting our ability to raise cash to purchase the notes and reducing the practical benefit to the holders of the notes of the repurchase provisions of the indenture that will govern the notes. See "Description of Notes—Certain Covenants—Repurchase of Notes Upon a Change of Control."

Your ability to transfer the notes may be limited by the absence of an active trading market.

There is no established public market for the notes and an active market for the notes may not develop or, if developed, such a market may not continue. In addition, the notes may trade at a discount from their initial offering price, depending upon prevailing interest rates, the market for similar notes, our performance and other factors. We do not intend to apply for listing or quotation of the exchange notes on any securities exchange or stock market. The liquidity of any market for the notes will depend on a number of factors, including:

•: the number of holders of notes;
•: our operating performance and financial condition;
•: the market for similar securities;
•: the interest of securities dealers in making a market in the notes; and
•: prevailing interest rates.

Historically, the market for non-investment grade debt has been subject to disruptions that have caused substantial volatility in the prices of these securities. We cannot assure you that the market for the notes will be free from similar disruptions. Any such disruptions could have an adverse effect on holders of the notes.

Table of Contents

The notes were issued with original issue discount ("OID") for U.S. federal income tax purposes.

Because the stated principal amount of the notes exceeds their issue price by more than ade minimis amount, the notes were treated as issued with OID for U.S. federal income tax purposes. Accordingly, holders subject to U.S. federal income taxation generally are required, for U.S. federal income tax purposes, to include the OID in gross income (as ordinary income) as such amounts accrue (on a constant yield to maturity basis), in advance of the receipt of cash payments to which the income is attributable and regardless of such holder's method of accounting for U.S. federal income tax purposes. See "Certain U.S. Federal Income Tax Considerations."

If a bankruptcy petition were filed by or against us, holders of notes may receive a lesser amount for their claim than they would have been entitled to receive under the indenture governing the notes.

If a bankruptcy petition were filed by or against us under the U.S. Bankruptcy Code, the claim by any holder of the notes for the principal amount of the notes may be limited to an amount equal to the sum of:

•: the original issue price for the notes; and
•: that portion of the original issue discount, if any, that does not constitute "unmatured interest" for purposes of the U.S. Bankruptcy Code.

Any original issue discount that was not amortized as of the date of the bankruptcy filing would constitute unmatured interest. Accordingly, because the notes were issued with an original issue discount, holders of the notes under these circumstances may receive a lesser amount than they would be entitled to under the terms of the indenture governing the notes, even if sufficient funds are available.

If you fail to exchange your original notes, you will face restrictions that will make the sale or transfer of your original notes more difficult.

If you do not exchange your original notes for new notes in the exchange offer, you will continue to be subject to the restrictions on transfer of your original notes described in the legend on your original notes. In general, you may only offer or sell the original notes if they are registered under the Securities Act and applicable state securities laws, or offered and sold under an exemption from those requirements. To the extent other original notes are tendered and accepted in the exchange offer and you elect not to exchange your original notes, the trading market, if any, for your original notes would be adversely affected because your original notes will be less liquid than the new notes. See "The Exchange Offer—Consequences of Failure to Exchange."

Some holders that exchange their original notes may be required to comply with registration and prospectus delivery requirements in connection with the sale or transfer of their new notes.

If you exchange your original notes in the exchange offer for the purpose of participating in a distribution of the new notes, you may be deemed to have received restricted securities and, if so, will be required to comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale transaction. If you are required to comply with the registration and prospectus delivery requirements, then you may face additional burdens on the transfer of your notes and could incur liability for failure to comply with applicable requirements.

Risks Related to Our Business

Risks Related to Our Business Strategy

We may not be able to execute our business strategy to transition to a leading IP infrastructure and managed services provider, which could adversely impact our results of operations and cash flows.

During 2010, we initiated a new business strategy to transition to a leading IP infrastructure and managed services provider. To implement this strategy, we plan to combine our existing business services with the integrated communications businesses of our recent acquisitions of ITC^DeltaCom, One Communications and STS. We plan to offer a comprehensive suite of business services under a new brand, EarthLink Business. There can be no assurance that our efforts will be successful. We may have difficulty managing and developing new products and services, entering into new markets or combining service offerings and sales forces, especially where we have no or limited direct prior experience or where competitors may have stronger market positions. We may not be able to achieve the name recognition or status under this new brand that we have anticipated. In order to be successful, we must also create economies of scale to allow us to increase revenues while incurring incremental costs that are proportionately lower than those applicable to the existing businesses. In addition, the capital expenditures required to support our new strategy may be greater than anticipated. Our revenues and the revenues of ITC^DeltaCom and One Communications have been declining and we expect the revenues from certain aspects of these businesses to continue to decline. Therefore, the inability to successfully implement our new business strategy to counteract these declining revenues could have an adverse impact on our business, financial condition, results of operations and cash flows.

We may be unsuccessful in making and integrating acquisitions into our business, which could result in operating difficulties, losses and other adverse consequences.

In late 2010 and early 2011, we completed our acquisitions of ITC^DeltaCom, One Communications and STS. Our ability to achieve the benefits of acquisitions depends in part on the integration and leveraging of technology, operations, sales and marketing channels and personnel. Integration and other risks associated with acquisitions can be more pronounced for larger and more complicated transactions or if multiple transactions are integrated simultaneously. The challenges and risks involved in the integration of acquired businesses and any future businesses that we may acquire include:

•: diversion of management's attention and resources that would otherwise be available for the current operation of our business;
•: failure to fully achieve expected synergies and costs savings;
•: higher integration costs than anticipated;
•: the impact on employee morale and the retention of employees, many of whom may have specialized knowledge about their business;
•: lost revenues or opportunities as a result of our current or potential customers or strategic partners deciding to delay or forego business;
•: difficulties combining product offerings and entering into new markets in which we are not experienced;
•: the integration of departments, operating support systems, such as billing systems, and technologies, such as network equipment;
•: the need to implement and maintain uniform controls, procedures and policies throughout all of our acquired companies or the need to remediate significant control deficiencies that may exist at acquired companies; and

Table of Contents

•: potential unknown liabilities.

We may not realize anticipated synergies, cost savings, growth opportunities and operational efficiencies from our acquisitions, or the anticipated benefits may take longer or present greater cost to realize than expected. The occurrence of any of these risks could have a material adverse effect on our business, results of operations, financial condition or cash flows.

We expect to continue to evaluate and consider potential strategic transactions that we believe may complement our business. At any given time, we may be engaged in discussions or negotiations with respect to one or more of such transactions that may be material to our financial condition and results of operations. There can be no assurance that any such discussions or negotiations will result in the consummation of any transaction, or that we will identify appropriate transactions on terms acceptable to us. Future acquisitions may result in significant costs and expenses and charges to earnings, including those related to severance pay, employee benefit costs, asset impairment charges, charges from the elimination of duplicative facilities and contracts, legal, accounting and financial advisory fees, and payments to executive officers and key employees under retention plans. Additionally, future acquisitions may result in the dilutive issuances of equity securities, use of our cash resources, incurrence of debt or contingent liabilities, amortization expense related to acquired definite-lived intangible assets or the potential impairment of amounts capitalized as intangible assets, including goodwill. Any of these items could have a material adverse affect on our business, financial condition, results of operations and cash flows.

We also may experience risks relating to the challenges and costs of closing a transaction and the risk that an announced transaction may not close. Completion of certain acquisition transactions are conditioned upon, among other things, the receipt of approvals, including from the FCC and certain state public utilities commissions. Failure to complete a pending transaction would prevent us from realizing the anticipated benefits. We would also remain liable for significant transaction costs, including legal and accounting fees, whether or not the transaction is completed.

The effects of adverse economic conditions could harm our business.

Unfavorable general economic conditions, including recession and disruptions to the credit and financial markets, could negatively affect our business. Our consumer access services are discretionary and dependent upon levels of consumer spending. In addition, our business customers are particularly exposed to a weak economy. These conditions could adversely affect the affordability of, and customer demand for, some of our products and services and could cause customers to delay or forgo purchases of our products and services. Also, our business customers may not be able to obtain adequate access to credit, which could affect their ability to make timely payments to us. One or more of these circumstances could cause our revenues to decline, churn to increase, allowance for doubtful accounts and write-offs of accounts receivable to increase or otherwise have a material adverse effect on our business, financial position, results of operations and cash flows.

Additionally, our business is dependent on third-party vendors for services and network equipment integral to our business, some of which may be experiencing financial distress. If these vendors encounter or continue to encounter financial difficulties, their ability to supply services and network equipment to us may be curtailed. If such vendors were to fail, we may not be able to replace them without disruption to, or deterioration of, our service and we may incur higher costs. Acquirers of distressed suppliers may not continue to upgrade technology associated with the type of equipment we use in our network. If we were required to purchase another manufacturer's equipment, we could incur significant initial costs to integrate the equipment into our network and to train personnel to use the new equipment, which could have an adverse effect on our financial condition and results of operations. Any interruption in the services provided by our third-party vendors could adversely affect our business, financial position, results of operations and cash flows.

Table of Contents

If we do not continue to innovate and provide products and services that are useful to individual subscribers and business customers, we may not remain competitive, and our revenues and operating results could suffer.

The market for Internet and telecommunications services is characterized by changing technology, changes in customer needs and frequent new service and product introductions, and we may be required to select one emerging technology over another. Our future success will depend, in part, on our ability to use leading technologies effectively, to continue to develop our technical expertise, to enhance our existing services and to develop new services that meet changing customer needs on a timely and cost-effective basis. We may not be able to adapt quickly enough to changing technology, customer requirements and industry standards. Such changes could include the increasing use of wireless forms of communication, such as handheld Internet-access devices and mobile phones, new competitors such as VoIP providers and the acceleration of the adoption of broadband due to government funding to deploy broadband to rural areas. In addition, the development and offering of new services in response to new technologies or consumer demands may require us to increase our capital expenditures significantly. Moreover, new technologies may be protected by patents or other intellectual property laws and therefore may be available only to our competitors and not to us. Any of these factors could adversely affect our revenues and profitability.

Our failure to implement cost reduction initiatives will adversely affect our results of operations.

We have adopted an operating framework that includes a disciplined focus on operational efficiency. The success of our operating efficiencies and cost reductions is necessary to achieve the desired synergies we hope to achieve with the integration of our recent and potential future acquisitions. In addition, as part of this framework, since 2007 we have implemented significant cost reduction initiatives, including reducing our headcount, outsourcing certain functions, streamlining internal processes, renegotiating contracts with network service providers and consolidating or closing certain facilities. We plan to continue to implement cost reduction initiatives and to manage our business more efficiently. However, we believe that large-scale cost reduction opportunities that we have previously experienced in our legacy business will be more limited in the future and in some cases, we may incur upfront costs in connection with implementing certain initiatives. In addition, although we seek to align our cost structure with trends in revenue for certain of our businesses, we do not expect to be able to reduce our cost structure in our Consumer Services segment to the same extent as those declines in revenue and our cost reduction initiatives might not yield the anticipated benefits. Finally, we may not be able to implement the same discipline for operations related to our recent and potential future acquisitions. If we do not recognize the anticipated benefits of our cost reduction initiatives, or do so in a timely manner, our profitability and cash flows will decline.

We will require a significant amount of cash, which may not be available to us, to service our debt and fund our other liquidity needs.

Our ability to repurchase, make payments on, or to refinance or repay, our debt, fund planned capital expenditures, pay quarterly cash dividends and continue to pursue our new business strategy, which may involve future acquisitions, will depend largely upon our future operating performance and our ability to access the capital markets. Our future operating performance is subject to general economic, financial, competitive, legislative and regulatory factors, as well as other factors that are beyond our control. Our business may not generate enough cash flow, or future borrowings may not be available to us, in an amount sufficient to enable us to pay our debt or fund our other liquidity needs. If we are forced to pursue any of the above options under distressed conditions, our business could be adversely affected.

In addition, adverse conditions in the capital markets, which in recent years have significantly reduced the availability of corporate credit, could continue to affect the global financial system and equity markets, which would limit our access to the debt and equity markets at a time when we would

Table of Contents

like, or need, to access such markets. This limitation could have an adverse effect on our flexibility to react to changing economic and business conditions.

Risks Related to Our Business Services Segment

We face significant competition in the communications industry that could reduce our profitability.

Integrated Communications. The communications industry is highly competitive, and we expect this competition to intensify. These markets are rapidly changing due to industry consolidation, an evolving regulatory environment and the emergence of new technologies. We compete directly or indirectly with incumbent local exchange carriers, such as AT&T, Qwest, Windstream and Verizon; other competitive telecommunications companies, such as Covad, Level 3, PAETEC and XO; interexchange carriers, such as Global Crossing and Sprint Nextel; wireless and satellite service providers; cable service providers, such as Charter Communications, Inc., Comcast, Cox Communications, Inc. and Time Warner Cable; and stand-alone VoIP providers. Competition could adversely impact us in several ways, including (i) the loss of customers and resulting revenue, (ii) the possibility of customers reducing their usage of our services or shifting to less profitable services, (iii) reduced traffic on our networks, (iv) our need to expend substantial time or money on new capital improvement projects, (v) our need to lower prices or increase marketing expenses to remain competitive and (vi) our inability to diversify by successfully offering new products or services.

We believe the primary competitive factors in the communications industry include price, availability, reliability of service, network security, variety of service offerings, quality of service and reputation of the service provider. While we believe our business services compete favorably based on some of these factors, we are at a competitive disadvantage relative to some or all of these factors with respect to some of our competitors. Many of our current and potential competitors have greater market presence, engineering, technical and marketing capabilities and financial, personnel and other resources substantially greater than ours; own larger and more diverse networks; are subject to less regulation; or have substantially stronger brand names. In addition, industry consolidation has resulted in larger competitors that have greater economies of scale. Consequently, these competitors may be better equipped to charge lower prices for their products and services, to provide more attractive offerings, to develop and expand their communications and network infrastructures more quickly, to adapt more swiftly to new or emerging technologies and changes in customer requirements, to increase prices that we pay for wholesale inputs to our services and to devote greater resources to the marketing and sale of their products and services.

We expect to continue to face significant pricing and product competition from AT&T and other incumbents that are or become the dominant providers of telecommunications services in our markets. We may be required to reduce further some or all of the prices we charge for our retail local, long distance and data services as a result of the mergers of BellSouth, SBC and AT&T and of MCI and Verizon Communications which have increased substantially their respective market power; the increase of cable companies, wireless carriers and providers of alternative forms of communication that rely on VoIP or similar applications; recent regulatory decisions that have decreased regulatory oversight of incumbent local telephone companies; and new broadband providers with cost structures lower than ours due to governmental subsidies. As a result, we may be required to reduce further some or all of the prices we charge for our retail local, long distance and data services which could adversely affect our revenues, cash flows and results of operations.

Web Hosting. The web hosting market is highly fragmented, has low barriers to entry and is characterized by considerable competition on price and features. We compete directly or indirectly with a number of companies, such as GoDaddy.com, Rackspace Hosting, Inc., Web.com and Yahoo!. Some of these companies have substantially greater market presence and greater financial, technical, marketing and other resources than we have. Competition could cause us to decrease the pricing of our

Table of Contents

services, increase churn of our existing customers, increase operating costs or decrease the number of subscribers we are able to add, which would result in lower revenues and profits.

Decisions by the Federal Communications Commission relieving incumbent carriers of certain regulatory requirements, and possible further deregulation in the future, may restrict our ability to provide services and may increase the costs we incur to provide these services.

We rely in significant part on purchasing wholesale services and leasing network facilities from AT&T and other incumbent carriers. Over the past several years, the FCC has reduced or eliminated a number of regulations governing the incumbent carriers' offerings, including removal of local switching and other network elements from the list of elements that the incumbent carriers must provide on an unbundled basis at TELRIC cost-based rates, as well as the grant of broad pricing flexibility to incumbents for their special access services in many areas. If the incumbent carriers do not continue to permit us to purchase these services from them under commercial arrangements at reasonable rates, our business could be adversely affected and our cost of providing local service could increase. This can have a significant adverse impact on our operating results and cash flows. If the FCC, Congress, state legislatures or state regulatory agencies were to adopt measures further reducing the local competition-related obligations of the incumbents or allowing those carriers to increase further the rates we must pay, we could experience additional increases in operating costs that would negatively affect our operating results and cash flows.

Our wholesale services, including our broadband transport services, will be adversely affected by pricing pressure, network overcapacity, service cancellations and other factors.

ITC^DeltaCom experienced, and we expect to continue to experience, adverse trends related to wholesale service offerings, including our broadband transport services and local interconnection business, which have resulted primarily from a reduction in rates charged to our customers due to overcapacity in the broadband services business and from service cancellations by some customers. Pending or contemplated consolidations in our industry also may continue to affect adversely our wholesale services business by improving the resources of the consolidating companies and reducing their demand for our services as those companies upgrade their own networks and consolidate their voice and data traffic on those networks. We expect that these factors will result in continued declines in revenues and cash flows from our wholesale service offerings. Such declines will have a disproportionately adverse effect on our operating results because of the higher gross margins associated with our wholesale services.

Our operating performance will suffer if we are not offered competitive rates for the access services we need to provide our long distance services.

We depend on other communications companies to originate and terminate a significant portion of the long distance traffic initiated by our customers. Our operating performance will suffer if we are not offered these access services at rates that are substantially equivalent to the costs of, and rates charged to, our competitors and that permit profitable pricing of our long distance services. The charges for access services historically have made up a significant percentage of our overall cost of providing long distance service. Some of our Internet-based competitors generally have been exempt from these and other regulatory charges, which could give them a significant cost advantage over us in this area. The FCC currently is considering what charges, if any, should be assessed on long distance and other interconnected voice services provided over the Internet.

Table of Contents

We may experience reductions in switched access and reciprocal compensation revenue.

Over the past several years, ITC^DeltaCom experienced a decline in its revenues for switched access and reciprocal compensation. These switched access and reciprocal compensation revenues may continue to decline as a result of lower volume of traditional long distance voice minutes and FCC and state regulations compelling a reduction of switched access and reciprocal compensation rates. The FCC has been considering proposals for an integrated intercarrier compensation regime under which all traffic exchanged between carriers would be subject to a unified rate. Such changes could materially reduce our switched access revenue from other carriers. We cannot predict the outcome of pending FCC rule makings related to intercarrier compensation. In addition, some states have adopted, and other states are considering, rules that lower or cap the switched access rates of competitive carriers. Switched access and reciprocal compensation together have been declining over time. There can be no assurance that we will be able to compensate for the reduction in intercarrier compensation revenue with other revenue sources or increased volume.

Our inability to maintain our network infrastructure, portions of which we do not own, could adversely affect our operating results.

We have effectively extended our network by entering into agreements with public utility companies to sell long-haul private line services on the fiber optic networks owned by these companies. Any cancellation or non-renewal of any of these agreements, any adverse legal ruling with respect to our rights under any of these agreements, or any future failure by us to acquire and maintain similar network agreements in these or other markets as necessary could materially adversely affect our operations. In addition, some of our agreements with the public utility companies are non-exclusive, and our business would suffer from any reduction in the amount of capacity they make available to us.

If we are unable to interconnect with AT&T, Verizon and other incumbent carriers on acceptable terms, our ability to offer competitively priced local telephone services will be adversely affected.

To provide local telephone services, we must interconnect with and resell the services of the incumbent carriers to supplement our own network facilities, pursuant to interconnection agreements between us and the incumbent carriers. As the original term of each of our interconnection agreements expires, it typically will be renewed on a month-to-month basis until it is replaced by a successor agreement. Further, federal regulators have adopted substantial modifications to the requirements that obligate AT&T, Verizon and other former monopoly local telephone companies to provide to us at cost-based rates the elements of their telephone networks that enable us to offer many of our services at competitive rates. Moreover, in areas outside of the territories of former Regional Bell Operating Companies in which we do business, such as the territories of CenturyLink, Frontier Communications, Fairpoint Communications, and Windstream, those incumbents carriers are subject to less wholesale regulation than are the RBOCs and tend to have less favorable interconnection options available to competitive carriers. If we are unable to enter into or maintain favorable interconnection agreements in our markets, our ability to provide local services on a competitive and profitable basis may be adversely affected. Any successful effort by the incumbent carriers to deny or substantially limit our access to their network elements or wholesale services also would harm our ability to provide local telephone services.

Table of Contents

We may not be able to compete effectively if we are unable to install additional network equipment or convert our network to more advanced technology.

We may find it necessary to install additional network equipment and/or to convert our existing network to a network using more advanced technology. We may not have or be able to raise the significant capital that a conversion may require, or be able to complete the installation of additional network equipment and the conversion to more advanced technology in a timely manner, at a commercially reasonable cost or at all. We also may face technological problems that cannot be resolved. If we are unable to successfully install or operate new network equipment or to convert our network to a network using more advanced technology, we may not be able to compete effectively, and our results of operations could be adversely affected.

Failure to obtain and maintain necessary permits and rights-of-way could interfere with our network infrastructure and operations.

To obtain and maintain rights-of-way and similar franchises and licenses needed to install, operate and maintain fiber optic cable and our other network elements, we must negotiate and manage agreements with state highway authorities, local governments, transit authorities, local telephone companies and other utilities, railroads, long distance carriers and other parties. For example, if we lose access to a right-of-way, we may need to spend significant amounts to remove and relocate our facilities.

Risks Related to Our Consumer Services Segment

We face significant competition in the Internet industry that could reduce our profitability.

We operate in the Internet access services market, which is extremely competitive. We compete directly or indirectly with established online services companies, such as AOL and the Microsoft Network; national communications companies and local exchange carriers, such as AT&T, Qwest and Verizon; cable companies providing broadband access, including Charter Communications, Inc., Comcast, Cox Communications, Inc. and Time Warner Cable; local and regional ISPs; free or value-priced ISPs, such as United Online, Inc. which provides service under the brands Juno and NetZero; wireless Internet service providers; content companies and email providers, such as Google and Yahoo!; and satellite and fixed wireless service providers. Competitors for our consumer VoIP services include established telecommunications and cable companies; ISPs; leading Internet companies; and companies that offer VoIP services as their primary business, such as Vonage. Competitors for our advertising services include major ISPs, content providers, large web publishers, web search engine and portal companies, Internet advertising providers, content aggregation companies, social-networking web sites, and various other companies that facilitate Internet advertising. Competition in the market for access services is likely to continue increasing, and competition could cause us to decrease the pricing of our services, increase churn of our existing customers, increase operating costs or decrease the number of subscribers we are able to add.

We believe the primary competitive factors in the Internet access service industry are price, speed, features, coverage area and quality of service. While we believe our Internet access services compete favorably based on some of these factors when compared to some Internet access providers, we are at a competitive disadvantage relative to some or all of these factors with respect to other of our competitors. Current and potential competitors include many large companies that have substantially greater market presence and greater financial, technical, marketing and other resources than we have. Our dial-up Internet access services do not compete favorably with broadband services with respect to speed, and dial-up Internet access services no longer have a significant, if any, price advantage over certain broadband services. Most of the largest providers of broadband services, such as cable and telecommunications companies, control their own networks and offer a wider variety of services than

Table of Contents

we offer, including voice, data and video services. Their ability to bundle services and to offer broadband services at prices below the price that we can profitably offer comparable services puts us at a competitive disadvantage. In addition, our only significant access to offer broadband services over cable is through our agreement with Time Warner.

We experience pricing pressures for certain of our consumer access services, particularly our consumer broadband services, due to competition, volume-based pricing and other factors. Some providers, including AT&T, have reduced and may continue to reduce the retail price of their Internet access services to maintain or increase their market share, which could cause us to reduce, or prevent us from raising, our prices. We may encounter further market pressures to: migrate existing customers to lower-priced service offerings; restructure service offerings to offer more value; reduce prices; and respond to particular short-term, market-specific situations, such as special introductory pricing or new product or service offerings. Any of the above could adversely affect our revenues and profitability.

Our consumer business is dependent on the availability of third-party network service providers.

Our consumer business depends on the capacity, affordability, reliability and security of third-party network service providers. Only a small number of providers offer the network services we require, and the majority of our network services are currently purchased from a limited number of network service providers. Our principal provider for narrowband services is Level 3. We also purchase narrowband services from certain regional and local providers. Our largest providers of broadband connectivity are AT&T, Bright House Networks, Comcast, Covad, Qwest, Time Warner Cable and Verizon. Network service providers have merged and may continue to merge, which would reduce the number of suppliers from which we could purchase network services.

We cannot be certain of renewal or non-termination of our contracts or that legislative or regulatory factors will not affect our contracts. Our results of operations could be materially adversely affected if we are unable to renew or extend contracts with our current network providers on acceptable terms, renew or extend current contracts with our network providers at all, acquire similar network capacity from other network providers, or otherwise maintain or extend our footprint. Additionally, each of our network providers sells network access to some of our competitors and could choose to grant those competitors preferential network access or pricing. Many of our network providers compete with us in the market to provide consumer Internet access. Such events may cause us to incur additional costs, pay increased rates for wholesale access services, increase the retail prices of our service offerings and/or discontinue providing retail access services, any of which could adversely affect our ability to compete in the market for retail access services.

The continued decline of our consumer access subscribers, combined with the change in mix of our consumer access base from narrowband to broadband, will adversely affect our results of operations.

Our consumer access revenues consist primarily of narrowband access revenues and broadband access revenues. Our narrowband subscriber base and revenues have been declining and are expected to continue to decline due to continued maturation of the market for narrowband access, increased availability and reduced pricing of broadband access services and an increase in advanced applications such as music downloads, videos, online gaming and social networking which require greater bandwidth for optimal performance. Our broadband subscriber base and revenues have been declining due to increased competition among broadband providers. We expect our consumer access subscriber base and revenues to continue to decline, which will adversely affect our profitability and results of operations. Our strategy for consumer access subscribers has been to reduce our sales and marketing efforts and focus instead on retaining customers and adding customers that are more likely to produce an acceptable rate of return. If we do not maintain our relationships with current customers or acquire new customers, our revenues will decline and our profitability will be adversely affected.

Table of Contents

Changes in the mix of our consumer access subscriber base, from narrowband access to broadband access, have also negatively affected our consumer access profitability. Our consumer broadband access services have lower gross margins due to the higher costs associated with delivering broadband services. Our ability to provide these services profitably is dependent upon cost-effectively purchasing wholesale broadband access and managing the costs associated with delivering broadband services. While we continuously evaluate cost reduction opportunities associated with the delivery of broadband access services, our overall profitability will be adversely affected if we are unable to continue to manage and reduce costs associated with the delivery of broadband services.

Our commercial and alliance arrangements may not be renewed or may not generate expected benefits, which could adversely affect our results of operations.

A significant number of our new consumer subscribers have been generated through strategic alliances, including through our marketing alliance with Time Warner Cable and Bright House Networks. Generally, our strategic alliances and marketing relationships are not exclusive and may have a short term. In addition, as our agreements expire or otherwise terminate we may be unable to renew or replace these agreements on comparable terms, or at all. Our inability to maintain our marketing relationships or establish new marketing relationships could result in delays and increased costs in adding paying subscribers and adversely affect our ability to add new customers, which could, in turn, have a material adverse effect on us. The number of customers we are able to add through these marketing relationships is dependent on the marketing efforts of our partners, and there is no commitment for these partners to provide us with new customers. A significant decrease in the number of gross subscriber additions generated through these relationships could adversely affect the size of our consumer customer base and revenues.

Privacy concerns relating to our business could damage our reputation and deter current and potential users from using our services.

Concerns about our practices with regard to the collection, use, disclosure or security of personal information or other privacy-related matters, even if unfounded, could damage our reputation and operating results. We strive to comply with all applicable data protection laws and regulations, as well as our own posted privacy policies. However, any failure or perceived failure to comply with these laws, regulations or policies may result in proceedings or actions against us by government entities or others, which could potentially have an adverse effect on our business.

In addition, as our services are web-based, we store a substantial amount of data on our servers for customers (including personal information). Any systems failure or compromise of our security that results in the release of our users' data could increase subscriber churn as well as limit our ability to attract new customers by damaging our reputation and brand. We may also need to expend significant resources to protect against security breaches.

Changes in technology in the Internet access industry could cause a decline in our business.

Our dial-up Internet access services rely on their compatibility with other third-party systems and products, including operating systems. Incompatibility with third-party systems and products could adversely affect our ability to deliver our services or a user's ability to access our services. Our dial-up services are dependent on dial-up modems and an increasing number of computer manufacturers do not pre-load their new computers with dial-up modems, requiring the user to separately acquire a modem to access our services. As the dial-up Internet access market declines and new technologies emerge, we may not be able to continue to effectively distribute and deliver our dial-up services.

The DSL portion of our broadband access business has also declined over the past several years, and we expect a continued decline in this business as a result of the advantages of the high-speed

Table of Contents

DOCSIS 3.0 technology offered by many cable broadband providers. This decline may adversely affect our broadband access business as our only other significant means of offering broadband services over cable is through our agreement with Time Warner Cable. In addition, advanced fiber-based technologies being utilized by AT&T and Verizon may also adversely affect both our dial-up and broadband access businesses.

General Risks

We may be unable to retain sufficient qualified personnel, and the loss of any of our key executive officers could adversely affect us.

Our business depends on the continued services of our senior management and other key personnel and our ability to retain and motivate them effectively. Competition for qualified personnel, including management, technical and sales personnel, may increase in a recovering economic environment. Acquisitions and workforce reductions may affect our ability to retain or replace key personnel, harm employee morale and productivity or disrupt our business. Key employees may depart because of issues relating to the uncertainty and difficulty of integration or a desire not to remain with us following a merger transaction. In addition, reductions in workforce have resulted in less redundancy of mission critical roles. Effective succession planning is important to our long-term success. Failure to ensure effective transfer of knowledge and transitions involving key employees could hinder execution of our business strategies. Finally, the loss of any of our key executives could impair our ability to implement our acquisition integration plans, execute our business strategy or otherwise have a material adverse effect on us.

Interruption or failure of our network and information systems and other technologies could impair our ability to provide our services, which could damage our reputation and harm our operating results.

Our network, network operations centers, central offices, corporate headquarters and those of our third party service providers are vulnerable to damage or interruption from earthquakes, hurricanes and other natural disasters, terrorist attacks, floods, fires, power loss, telecommunications failures, break ins, human error, computer denial of service attacks, computer hackings, computer viruses, worms or other attempts to harm our systems, and similar events. Some of our systems are not fully redundant, and our disaster recovery planning may not be adequate. Further, any security breaches, such as misappropriation, misuse, leakage, falsification or accidental release or loss of information maintained in our information technology systems and networks, including customer, personnel and vendor data, could damage our reputation and require us to expend significant capital and other resources to remedy any such security breach. We may experience service interruptions or system failures in the future. In addition, as we consider potential outsource or network consolidation opportunities, we may experience service interruptions despite our efforts to minimize the impact to customers. Any service interruption adversely affects our ability to operate our business and could result in an immediate loss of revenues. If we experience frequent or persistent system or network failures, our reputation and brand could be permanently harmed. We may make significant capital expenditures to increase the reliability of our systems, but these capital expenditures may not achieve the results we expect. The occurrence of any such network, email or information system-related events or security breaches could have a material adverse effect on our business, financial position, results of operations and cash flows.

Our ability to provide communications services also could be materially adversely affected by a cable cut, switch failure or other equipment failure along our fiber optic network or along any other fiber optic network on which we lease transmission capacity. A significant portion of our fiber optic network is not protected by electronic redundancy or geographical diverse routing. Lack of these safeguards could result in our inability to reroute traffic to another fiber in the same fiber sheath in the event of a partial fiber cut or electronics failure or to an entirely different fiber optic route, assuming

Table of Contents

capacity is available, if there occurs a total cable cut or if we fail to maintain our rights-of-way on some routes.

In addition, our consumer VoIP services, including our E911 service, depend on the proper functioning of facilities and equipment owned and operated by third parties and is, therefore, beyond our control. If our third party service providers fail to maintain these facilities properly, or fail to respond quickly to problems, our customers may experience service interruptions. In addition, our E911 emergency service for our VoIP services is different in significant respects from the emergency calling services offered by traditional wireline telephone companies. Those differences may cause significant delays, or even failures, in callers' receipt of the emergency assistance they need. VoIP providers are not currently protected by legislation, so any resulting liability could be substantial. If interruptions or delays adversely affect the perceived reliability of our service, we may have difficulty attracting new customers and our brand and reputation may be negatively impacted. Any of these factors could cause us to lose revenues, incur greater expenses or cause our reputation or financial results to suffer.

Our business depends on effective business support systems and processes.

Our business relies on our data, billing and other operational and financial reporting and control systems. To effectively manage our technical support infrastructure, especially as we make acquisitions, we will need to continue to maintain our data, billing, and other operational and financial systems, procedures and controls, which can be costly. We have experienced system failures from time to time, and any interruption in the availability of our business support systems, in particular our billing system, could result in an immediate, and possibly substantial, loss of revenues. Frequent or persistent system failures could cause customers to believe our systems are unreliable, leading them to switch to our competitors and could permanently harm our reputation.

Our Business Services segment also depends on operations support systems and other carriers to order and receive network elements and wholesale services from the incumbent carriers. These systems are necessary for carriers like us to provide local service to customers on a timely and competitive basis. FCC rules, together with rules adopted by state public utility commissions, may not be implemented in a manner that will permit us to order, receive, provision and maintain network elements and other facilities in the manner necessary for us to provide many of our services.

Government regulations could adversely affect our business or force us to change our business practices.

Our services are subject to varying degrees of federal, state and local regulation and, in light of our recent and pending acquisitions and the growth of our Business Services segment, will be more affected by regulation than in the past. Federal, state and local regulations governing our services are the subject of ongoing judicial proceedings, rulemakings and legislative initiatives, that could change the manner in which our industry operates and affect our business.

Business Services Segment Regulation

Through our wholly-owned subsidiaries, we hold numerous federal and state regulatory authorizations. The Federal Communications Commission (FCC) exercises jurisdiction over telecommunications common carriers to the extent that they provide, originate or terminate interstate or international communications. The FCC also establishes rules and has other authority over some issues related to local telephone competition. State regulatory commissions retain jurisdiction over telecommunications carriers to the extent that they provide, originate or terminate intrastate communications. Both the FCC and the state commissions have authority to regulate the prices, terms, and conditions of communications services that we offer to customers, and have jurisdiction to adjudicate complaints against us by customers regarding such matters. State commissions also have authority to review and approve interconnection agreements between incumbent telephone carriers and

Table of Contents

competitive carriers such as us, and to conduct arbitration of disputes arising in the negotiation of such agreements, including authority to determine the prices, terms, and conditions of some services and facilities we obtain from the incumbent telephone carriers. Local governments may require us to obtain licenses, permits or franchises to use the public rights-of-way necessary to install and operate our network.

The regulatory environment relating to our Business Services segment continues to evolve. Rules and decisions of the FCC and the state regulatory commissions are subject to court review, and policies affecting us may change as a result of judicial decisions in ways that are difficult to predict. Bills intended to amend the Communications Act of 1934, as amended by the Telecommunications Act of 1996 ("Communications Act") are introduced in Congress from time to time and their effect on us and the communications industry cannot always be predicted. Proposed legislation, if enacted, could have a significant effect on our business, particularly if the legislation impairs our ability to interconnect with incumbent carrier networks, lease portions of other carriers' networks or resell their services at reasonable prices, or lease elements of networks of the ILECs under acceptable rates, terms and conditions. We cannot predict the outcome of any ongoing legislative initiatives or administrative or judicial proceedings or their potential impact upon the communications and information technology industries generally or upon us specifically.

Failure to make proper payments for federal Universal Service Fund assessments, FCC regulatory fees or other amounts mandated by federal and state regulations; failure to maintain proper state tariffs and certifications; failure to comply with federal, state or local laws and regulations; failure to obtain and maintain required licenses, franchises and permits; imposition of burdensome license, franchise or permit requirements for us to operate in public rights-of-way; and imposition of new burdensome or adverse regulatory requirements could limit the types of services we provide or the terms on which we provide these services.

The FCC and many state regulatory commissions must grant approval before any change in control of any carrier providing communications services, or of any entity controlling such a carrier, and before the assignment of any authorizations held by such a carrier. We were required to, and did, obtain such approvals for each of our recent acquisitions, which increased our transaction costs and delayed the closing of the transactions. If we wish to make additional acquisitions of communications carriers in the future, we cannot be certain that we will be able to obtain all required regulatory approvals on a timely basis and without burdensome conditions.

Consumer Services Segment Regulation

Narrowband Internet access. Currently, narrowband Internet access is classified as an "information service" and is not subject to traditional telecommunications services regulation, such as licensing or pricing regulation. Any change to these rules that would apply per-minute carrier access charges to dial-up Internet access traffic could significantly impact our costs for this service. While Internet traffic is not subject to the FCC's carrier access charge regime, dial-up ISP bound traffic is regulated by the FCC. The FCC has established a uniform, nationwide rate for ISP-bound traffic, but these rules have been criticized by the courts and further judicial scrutiny is expected. Changes to the rules governing dial-up ISP bound traffic could impact our cost of providing this service.

Internet taxation. The Internet Tax Non-Discrimination Act, which is in effect through November 2014, places a moratorium on taxes on Internet access and multiple, discriminatory taxes on electronic commerce. Certain states have enacted various taxes on Internet access and electronic commerce, and selected states' taxes are being contested on a variety of bases. If these state tax laws are not successfully contested, or if future state and federal laws imposing taxes or other regulations on Internet access and electronic commerce are adopted, our cost of providing Internet access services could be increased and our business could be adversely affected.

Table of Contents

Universal Service. While current policy exempts broadband access services from the Universal Service Fund ("USF"), the Congress and FCC may consider expanding the USF to include broadband Internet access services. This change could allow broadband service providers to receive a subsidy for deploying broadband in rural and underserved areas, but it will most likely require broadband service providers to contribute to the fund as well. If broadband Internet access providers become subject to USF contribution obligations, they would likely impose a USF surcharge on end users. Such a surcharge will raise the effective cost of our broadband services to our customers, and could adversely affect customer satisfaction or our revenues and profitability.

VoIP regulation. The current regulatory environment for VoIP services remains unclear, as the decision whether VoIP is an "information service" or "telecommunications service" is still pending. Classifying VoIP as a telecommunications service could require us to obtain telecommunications licenses, comply with numerous legacy telephone regulations, and possibly subject the VoIP traffic to inter-carrier access charges, which could result in increased costs.

General Regulation

Consumer protection. Federal and state governments have adopted consumer protection laws and undertaken enforcement actions to address advertising and user privacy. Our services and business practices, or changes to our services and business practices could subject us to investigation or enforcement actions if we fail to adequately comply with applicable consumer protection laws. Existing and future federal and state laws and regulations also may affect the manner in which we are required to protect confidential customer data and other information, which could increase the cost of our operations and our potential liability if the security of our confidential customer data is breached.

Broadband Internet access. Currently, broadband Internet access is classified as an "information service" and, as a result, cable companies and telephone companies that offer a broadband Internet access information service are not required by the FCC to offer unaffiliated ISPs stand-alone broadband transmission. Accordingly, if our contracts with cable companies and telephone companies were to expire and not be replaced, our broadband Internet access customer base and revenues would be adversely affected.

Forbearance. If the FCC were to forbear from enforcing regulations that have been established to enable competing broadband Internet access and VoIP, our consumer services business could be adversely affected. In addition, with respect to our business services, regulatory authorities generally have decreased their oversight of incumbent carriers and from time to time are asked to forbear from applying a range of regulations to incumbent carriers, which may increase the competitive benefits these companies experience from their longstanding customer relationships and greater financial and technical resources, and may increase their ability to reduce prices for local and other network services by offsetting those reductions with revenue or profits generated by unrelated businesses, products or services.

Other laws and regulations. Our business also is subject to a variety of other U.S. laws and regulations from various entities, including the Federal Trade Commission, the Environmental Protection Agency, and the Occupational Safety and Health Administration, as well as by state and local regulatory agencies, that could subject us to liabilities, claims or other remedies. Compliance with these laws and regulations is complex and may require significant costs. In addition, the regulatory framework relating to Internet and communications services is evolving and both the federal government and states from time to time pass legislation that impacts our business. It is likely that additional laws and regulations will be adopted that would affect our business. We cannot predict the impact future laws, regulatory changes or developments may have on our business, financial condition, results of operations or cash flows. The enactment of any additional laws or regulations, increased enforcement activity of existing laws and regulations, or claims by individuals could significantly impact

Table of Contents

our costs or the manner in which we conduct business, all of which could adversely impact our results of operations and cause our business to suffer.

For example, changes in policies or regulations mandating new environmental standards could increase our operating costs, such as utility costs at our switch sites, and changes in tax laws or the interpretation of existing tax laws by state and local authorities could increase our income, sales, property or other tax costs. In addition, our operations are subject to a variety of laws and regulations relating to the protection of the environment, including those governing the cleanup of contamination and the management and disposal of hazardous substances and wastes. As an owner or operator of property, we could incur significant costs as a result of violations or liabilities under such laws and regulations, including fines, penalties, cleanup costs and third-party claims.

Our business may suffer if third parties used for customer service and technical support and certain billing services are unable to provide these services or terminate their relationships with us.

Our business and financial results depend, in part, on the availability and quality of our customer service and technical support and certain billing services, including collection services. Our Consumer Services segment outsources a majority of our customer service and technical support functions and relies primarily on one customer service and technical support vendor. As a result, we maintain only a small number of internal customer service and technical support personnel. We are not currently equipped to provide the necessary range of service and support functions in the event that our service providers become unable or unwilling to offer these services to us. Our outsourced customer support providers utilize international locations to provide us with customer service and technical support services, and as a result, our customer support providers may become subject to financial, economic, environmental and political risks beyond our or the providers' control, which could jeopardize their ability to deliver customer service and technical support services. We also utilize third parties for certain billing and collection services and for our web hosting services. If one or more of our service providers does not provide us with quality services, or if our relationship with any of our third party vendors terminates and we are unable to provide those services internally or identify a replacement vendor in an orderly, cost-effective and timely manner, our business, financial position, results of operations and cash flows could suffer.

We may not be able to protect our intellectual property.

We regard our EarthLink, EarthLink Business, EarthLink Carrier and PeoplePC trademarks as valuable assets to our business. In particular, we believe the strength of the EarthLink, EarthLink Business and PeoplePC brands among existing and potential customers is important to the success of our business. Additionally, our EarthLink, EarthLink Business and PeoplePC service marks, proprietary technologies, domain names and similar intellectual property are also important to the success of our business. We principally rely upon trademark law as well as contractual restrictions to establish and protect our technology and proprietary rights and information. We require employees and consultants and, when possible, suppliers and distributors to sign confidentiality agreements, and we generally control access to, and distribution of, our technologies, documentation and other proprietary information. The efforts we have taken to protect our proprietary rights may not be sufficient or effective. Third parties may infringe or misappropriate our trademarks and similar proprietary rights. If we are unable to protect our proprietary rights from unauthorized use, our brand image may be harmed and our business may suffer. In addition, protecting our intellectual property and other proprietary rights is expensive and time consuming. Any increase in the unauthorized use of our intellectual property could make it more expensive to do business and consequently harm our operating results.

Table of Contents

We may be accused of infringing upon the intellectual property rights of third parties, which is costly to defend and could limit our ability to use certain technologies in the future.

From time to time, third parties have alleged that we infringe on their intellectual property rights. We may be unaware of filed patent applications and of issued patents that could be related to our products and services. Some of the largest communications providers, such as AT&T, Sprint and Verizon, have substantial patent holdings. These providers have successfully asserted their claims against some communications companies, and have filed pending lawsuits against various competitive carriers. We have been subject to, and expect to continue to be subject to, claims and legal proceedings regarding alleged infringement by us of the patents, trademarks and other intellectual property rights of third parties. None of these claims has had an adverse effect on our ability to market and sell and support our services. Such claims, whether or not meritorious, are time-consuming and costly to resolve, and could require expensive changes in our methods of doing business, could require us to enter into costly royalty or licensing agreements, or could require us to cease conducting certain operations. Any of these events could result in increases in operating expenses or could limit or reduce the number of our service offerings.

If we, or other industry participants, are unable to successfully defend against legal actions, we could face substantial liabilities or suffer harm to our financial and operational prospects.

We are currently a party to various legal actions, including consumer class action, patent litigation and legal proceedings regarding the use of rights-of-way for our network. Defending against these lawsuits may involve significant expense and diversion of management's attention and resources from other matters. Due to the inherent uncertainties of litigation, we may not prevail in these actions. In addition, our ongoing operations may subject us to litigation risks and costs in the future. Both the costs of defending lawsuits and any settlements or judgments against us could materially and adversely affect our results of operations.

We also expect to continue to be subject to the risks associated with the resolution of various third-party disputes, lawsuits, arbitrations and proceedings affecting our business, particularly our Business Services segment. The deregulation of the telecommunications industry, the implementation of the Telecommunications Act of 1996, the evolution of telecommunications infrastructure from time-division multiplexing to Internet Protocol, and the distress of many carriers in the telecommunications industry as a result of continued competitive factors and financial pressures have resulted in the involvement of numerous industry participants in disputes, lawsuits, proceedings and arbitrations before state and federal regulatory commissions, private arbitration organizations such as the American Arbitration Association, and courts over many issues that will be important to our financial and operational success. These issues include the interpretation and enforcement of existing interconnection agreements and tariffs, the terms of new interconnection agreements, operating performance obligations, intercarrier compensation, treatment of different categories of traffic (for example, traffic originated or terminated on wireless or VoIP), the jurisdiction of traffic for intercarrier compensation purposes, the wholesale services and facilities available to us, the prices we will pay for those services and facilities, and the regulatory treatment of new technologies and services.

We may be required to recognize additional impairment charges on our goodwill and intangible assets, which would adversely affect our results of operations and financial position.

We have recorded goodwill and other intangible assets in connection with our acquisitions, including $170.1 million of goodwill resulting from our acquisition of ITC^DeltaCom. We perform an impairment test of our goodwill and indefinite-lived intangible assets annually during the fourth quarter of our fiscal year or when events occur or circumstances change that would more likely than not indicate that goodwill or any such assets might be impaired. We evaluate the recoverability of our definite-lived intangible assets for impairment when events occur or circumstances change that would

Table of Contents

indicate that the carrying amount of an asset may not be recoverable. Factors that may be considered a change in circumstances, indicating that the carrying value of our goodwill or intangible assets may not be recoverable, include a decline in stock price and market capitalization, reduced future cash flow estimates, higher customer churn, and slower growth rates in our industry. We have experienced impairment charges in the past. As we continue to assess the ongoing expected cash flows and carrying amounts of our goodwill and other intangible assets, changes in economic conditions, changes to our business strategy, changes in operating performance or other indicators of impairment could cause us to realize a significant impairment charge, negatively impacting our results of operations and financial position.

We may have to undertake further restructuring plans that would require additional charges, including incurring facility exit and restructuring charges.

Over the past few years, we implemented a corporate restructuring plan under which we significantly reduced our workforce and closed or consolidated various facilities. Our continued focus on maintaining operational efficiency may result in additional restructuring activities or changes in estimates to amounts previously recorded. We may choose to divest certain business operations based on our management's assessment of their strategic value to our business, further consolidate or close certain facilities or outsource certain functions, including network and data center consolidation. Decisions to eliminate or limit certain business operations in the future could involve the expenditure of capital, consumption of management resources, realization of losses, transition and wind-up expenses, further reduction in workforce, impairment of the value of purchased assets, facility consolidation and the elimination of revenues along with associated costs, any of which could cause our operating results to decline and may fail to yield the expected benefits. Engaging in further restructuring and integration activities could result in additional charges and costs, including facility exit and restructuring costs, and could adversely affect our business, financial position, results of operations and cash flows.

We may have exposure to greater than anticipated tax liabilities and the use of our net operating losses and certain other tax attributes could be limited in the future.

As of March 31, 2011, we had approximately $498.9 million of tax net operating losses for federal income tax purposes and approximately $771.0 million of tax net operating losses for state income tax purposes. The tax net operating losses for federal income tax purposes begin to expire in 2020 and the tax net operating losses for state income tax purposes began to expire in 2010. Additionally, we acquired companies with existing federal and state net operating losses.

Our future income taxes could be adversely affected by changes in the valuation of our deferred tax assets and liabilities or by changes in tax laws, regulations, accounting principles or interpretations thereof. Our determination of our tax liability is always subject to review by applicable tax authorities. Any adverse outcome of such a review could have a negative effect on our operating results and financial condition. In addition, the determination of our provision for income taxes and other tax liabilities requires significant judgment, and there are many transactions and calculations where the ultimate tax determination is uncertain. Although we believe our estimates are reasonable, the ultimate tax outcome may differ from the amounts recorded in our financial statements and may materially affect our financial results in the period or periods for which such determination is made.

An "ownership change" that occurs during a "testing period" (as such terms are defined in Section 382 of the Internal Revenue Code of 1986, as amended) could place significant limitations, on an annual basis, on the use of such net operating losses to offset future taxable income we may generate. In general, future stock transactions and the timing of such transactions could cause an "ownership change" for income tax purposes. Such transactions may include our purchases under our share repurchase program, additional issuances of common stock by us (including but not limited to

Table of Contents

issuances upon future conversion of our outstanding convertible senior notes), and acquisitions or sales of shares by certain holders of our shares, including persons who have held, currently hold, or may accumulate in the future five percent or more of our outstanding stock. Many of these transactions are beyond our control. Calculations of an "ownership change" under Section 382 are complex and to some extent are dependent on information that is not publicly available. The risk of an "ownership change" occurring could increase if additional shares are repurchased, if additional persons acquire five percent or more of our outstanding common stock in the near future and/or current five percent stockholders increase their interest. Due to this risk, we monitor our purchases of additional shares of our common stock. Since an "ownership change" also could result from a change in control of our company, with subsequent annual limitations on the use of our net operating losses, this could discourage a change in control.

THE EXCHANGE OFFER

Terms of the Exchange Offer

Purpose of the Exchange Offer

We sold $300,000,000 in principal amount of the original notes on May 17, 2011, in a transaction exempt from the registration requirements of the Securities Act. The initial purchasers of the original notes subsequently resold the original notes to qualified institutional buyers in reliance on Rule 144A under the Securities Act.

In connection with the sale of original notes to the initial purchasers pursuant to a purchase agreement, dated May 12, 2011, among us and the initial purchasers named therein, the holders of the original notes became entitled to the benefits of a registration rights agreement dated May 17, 2011 among us, the guarantors named therein and the initial purchasers named therein.

The registration rights agreement provides that, unless the exchange offer would violate applicable law or any applicable interpretation of the staff of the SEC, we:

•: will file an exchange offer registration statement for the notes with the SEC no later than 90 days after May 17, 2011;
•: will use our commercially reasonable efforts to cause the SEC to declare the exchange offer registration statement effective under the Securities Act no later than 180 days after May 17, 2011;
•: will use our commercially reasonable efforts to complete the exchange of the new notes for all original notes tendered prior thereto in the exchange offer no later than 30 days after the exchange offer registration statement is declared effective; and
•: will keep the registered exchange offer open for not less than 20 business days (or longer if required by applicable law or otherwise extended by us, at our option) after the date notice of the registered exchange offer is mailed to the holders of the original notes.

The exchange offer being made by this prospectus, if consummated within the required time periods, will satisfy our obligations under the registration rights agreement. This prospectus, together with the letter of transmittal, is being sent to all beneficial holders of original notes known to us.

The terms of the new notes issued in exchange for the original notes will be substantially identical to the terms of the original notes, except that the new notes are registered under the Securities Act, and the transfer restrictions, registration rights and related additional interest terms applicable to the original notes will not apply to the new notes. The new notes will evidence the same indebtedness as the original notes and will be entitled to the benefits of the indenture. The new notes will be treated as a single class under the indenture with any original notes that remain outstanding.

Upon the terms and subject to the conditions set forth in this prospectus and in the accompanying letter of transmittal, we will accept all original notes properly tendered and not withdrawn prior to the expiration date. The new notes will be issued in denominations of $2,000 in principal amount or any integral multiple of $1,000 in excess thereof in exchange for each $2,000 in principal amount or any integral multiple of $1,000 in excess thereof of outstanding original notes accepted in the exchange offer. Holders may tender some or all of their original notes pursuant to the exchange offer.

Based on existing interpretations of the SEC contained in several no-action letters to third parties we believe that holders of the new notes issued in exchange for original notes may offer for resale, resell and otherwise transfer the new notes, other than any holder that is an affiliate of ours within the meaning of Rule 405 under the Securities Act, without compliance with the registration and prospectus delivery provisions of the Securities Act. This is true as long as (i) the new notes are acquired in the

Table of Contents

ordinary course of the holder's business, (ii) the holder is not engaging in or intending to engage in a distribution of the new notes, and (iii) the holder has no arrangement or understanding with any person to participate in the distribution of the new notes. A broker-dealer that acquired original notes directly from us cannot exchange the original notes in the exchange offer. Any holder who tenders in the exchange offer for the purpose of participating in a distribution of the new notes cannot rely on the no-action letters of the staff of the SEC and must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale transaction.

Each broker-dealer that receives new notes for its own account in exchange for original notes, where such original notes were acquired by such broker-dealer as a result of market-making or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of such new notes. See "Plan of Distribution" for additional information.

We will accept validly tendered original notes promptly following the expiration of the exchange offer by giving written notice of the acceptance of such notes to the exchange agent. The exchange agent will act as agent for the tendering holders of original notes for the purposes of receiving the new notes from the issuer and delivering new notes to such holders.

If any tendered original notes are not accepted for exchange because of an invalid tender or the occurrence of the conditions set forth under "The Exchange Offer—Conditions" without waiver by us, certificates for any such unaccepted original notes will be returned, without expense, to the tendering holder of any such original notes promptly after the expiration date.

Holders of original notes who tender in the exchange offer will not be required to pay brokerage commissions or fees or, subject to the instructions in the letter of transmittal, transfer taxes with respect to the exchange of original notes, pursuant to the exchange offer. We will pay all charges and expenses, other than certain applicable taxes in connection with the exchange offer. See "The Exchange Offer—Fees and Expenses."

Holders of original notes do not have any appraisal or dissenters' rights under the Delaware General Corporation Law in connection with the exchange offer.

Shelf Registration Statement

Pursuant to the registration rights agreement, we have agreed to file a shelf registration statement if:

•: after we have unsuccessfully sought a no-action letter or other favorable ruling from the SEC to permit the consummation of the exchange offer, we are not permitted to file the exchange offer registration statement or consummate the exchange offer because the exchange offer is not permitted by applicable law or SEC policy,
•: the exchange offer is not consummated within 210 days after the issue date of the original notes, or
•: upon the request of any holder, if such holder (i) is prohibited by applicable law or SEC policy from participating in the exchange offer, (ii) may not resell the new notes acquired by it in the exchange offer to the public without delivering a prospectus and the prospectus contained herein is not appropriate or available for such resales by such holder, or (c) is a broker-dealer and holds original notes acquired directly from us or one of our affiliates.

We have agreed to file a shelf registration statement with the SEC as soon as practicable, but in any event no later than the earliest to occur of (i) 30 days after we determine we are required to file an exchange offer registration statement, (ii) 30 days after so required or requested by certain holders in accordance with the immediately preceding paragraph and (iii) 210 days after May 17, 2011. Thereafter, we have agreed to use our commercially reasonable efforts to cause such shelf registration

Table of Contents

statement to be declared effective by the SEC within 60 days after being so required. In addition, we agreed to use our commercially reasonable efforts to keep that shelf registration statement continually effective, supplemented and amended for a period of two years following the date the shelf registration statement is declared effective or such shorter period which terminates when all notes covered by that shelf registration statement have been sold under it.

A holder that sells original notes pursuant to the shelf registration statement will be required to be named as a selling securityholder in the related prospectus and must deliver a prospectus to purchasers, because a seller will be subject to certain of the civil liability provisions under the Securities Act in connection with these sales. A seller of the original notes also will be bound by applicable provisions of the applicable registration rights agreement, including indemnification obligations. In addition, each holder of original notes must deliver information requested by us to be used in connection with the shelf registration statement within 20 business days of our request in order to have its original notes included in the shelf registration statement and benefit from the provisions regarding any additional interest in the registration rights agreement.

Additional Interest in Certain Circumstances

Pursuant to the registration rights agreement, we will be required to pay additional interest if a registration default exists. A registration default will exist if:

•: any registration statement required by the registration rights agreement is not filed by the date specified for filing;
•: any registration statement required by the registration rights agreement is not declared effective by the SEC on or prior to the date specified for effectiveness;
•: the exchange offer is not consummated within 210 business days after May 17, 2011; or
•: any registration statement required by the registration rights agreement is declared effective but thereafter ceases to be effective be effective or fails to be usable for its intended purpose without being succeeded immediately by a post-effective amendment that cures such failure.

Additional interest will accrue on the principal amount of the original notes (in addition to the stated interest on the original notes) following the date on which any of the registration defaults described above has occurred and will continue until all registration defaults have been cured. Additional interest will accrue at a rate of 0.25% per annum during the 90-day period immediately following the occurrence of a registration default and will increase by 0.25% per annum at the end of each subsequent 90-day period while a registration default is continuing, up to a maximum rate of additional interest of 1.00% per annum. Any amounts of additional interest due will be payable in cash on the same interest payment dates as the original notes.

Expiration Date; Extensions; Amendment

We will keep the exchange offer open for not less than 20 business days, or longer if required by applicable law, after the date on which notice of the exchange offer is mailed to the holders of the original notes. The term "expiration date" means the expiration date set forth on the cover page of this prospectus, unless we extend the exchange offer, in which case the term "expiration date" means the latest date to which the exchange offer is extended.

In order to extend the expiration date, we will notify the exchange agent of any extension by written notice and will issue a public announcement of the extension, each prior to 9:00 a.m., New York City time, on the next business day after the previously scheduled expiration date.

Table of Contents

We reserve the right

•: to delay accepting any original notes and to extend the exchange offer or to terminate the exchange offer and not accept original notes not previously accepted if any of the conditions set forth under "Conditions" shall have occurred and shall not have been waived by us, if permitted to be waived by us, by giving written notice of such delay, extension or termination to the exchange agent, or
•: to amend the terms of the exchange offer in any manner deemed by us to be advantageous to the holders of the original notes. (We are required to extend the offering period for certain types of changes in the terms of the exchange offer, for example, a change in the consideration offered or percentage of original notes sought for tender.)

All conditions set forth under "The Exchange Offer—Conditions" must be satisfied or waived prior to the expiration date.

Any delay in acceptance, extension, termination or amendment will be followed as promptly as practicable by written notice. If the exchange offer is amended in a manner determined by us to constitute a material change, we will promptly disclose such amendment in a manner reasonably calculated to inform the holders of the original notes of such amendment. In the event of a material change in the exchange offer, including the waiver of a material condition by us, we will extend the exchange offer, if necessary, so that at least five business days remain prior to the expiration date following the notice of the material change.

Without limiting the manner in which we may choose to make a public announcement of any extension, amendment or termination of the exchange offer, we will not be obligated to publish, advertise, or otherwise communicate any such announcement, other than by making a timely release to an appropriate news agency.

Exchange Offer Procedures

To tender in the exchange offer, a holder must complete, sign and date the letter of transmittal, or a facsimile thereof, have the signatures on the letter of transmittal guaranteed if required by instruction 2 of the letter of transmittal, and mail or otherwise deliver the letter of transmittal or such facsimile or an agent's message in connection with a book entry transfer, together with the original notes and any other required documents. To be validly tendered, such documents must reach the exchange agent before 11:59 p.m., New York City time, on the expiration date. Delivery of the original notes may be made by book-entry transfer in accordance with the procedures described below. Confirmation of such book-entry transfer must be received by the exchange agent prior to the expiration date.

The term "agent's message" means a message, transmitted by a book-entry transfer facility to, and received by, the exchange agent, forming a part of a confirmation of a book-entry transfer, which states that such book-entry transfer facility has received an express acknowledgment from the participant in such book-entry transfer facility tendering the original notes that such participant has received and agrees to be bound by the terms of the letter of transmittal and that we may enforce such agreement against such participant.

The tender by a holder of original notes will constitute an agreement between such holder and us in accordance with the terms and subject to the conditions set forth in this prospectus and in the letter of transmittal.

Delivery of all documents must be made to the exchange agent at its address set forth below. Holders may also request their respective brokers, dealers, commercial banks, trust companies or nominees to effect such tender for such holders.

Table of Contents

Each broker-dealer that receives new notes for its own account in exchange for original notes, where such original notes were acquired by such broker-dealer as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of such new notes. See "Plan of Distribution."

The method of delivery of original notes and the letter of transmittal and all other required documents to the exchange agent is at the election and risk of the holders. Instead of delivery by mail, it is recommended that holders use an overnight or hand delivery service. In all cases, sufficient time should be allowed to assure timely delivery to the exchange agent before 11:59 p.m., New York City time, on the expiration date. No letter of transmittal or original notes should be sent to us.

Only a holder of original notes may tender original notes in the exchange offer. The term "holder" with respect to the exchange offer means any person in whose name original notes are registered on our books or any other person who has obtained a properly completed bond power from the registered holder.

Any beneficial holder whose original notes are registered in the name of its broker, dealer, commercial bank, trust company or other nominee and who wishes to tender should contact such registered holder promptly and instruct such registered holder to tender on its behalf. If such beneficial holder wishes to tender on its own behalf, such registered holder must, prior to completing and executing the letter of transmittal and delivering its original notes, either make appropriate arrangements to register ownership of the original notes in such holder's name or obtain a properly completed bond power from the registered holder. The transfer of record ownership may take considerable time.

Signatures on a letter of transmittal or a notice of withdrawal, must be guaranteed by an "eligible guarantor institution" within the meaning of Rule 17Ad-15 under the Securities Exchange Act of 1934, as amended (the "Exchange Act") unless the original notes are tendered:

•: by a registered holder who has not completed the box entitled "Special Issuance Instructions" or "Special Delivery Instructions" on the letter of transmittal or
•: for the account of an eligible guarantor institution.

In the event that signatures on a letter of transmittal or a notice of withdrawal are required to be guaranteed, such guarantee must be by an eligible guarantor institution.

If a letter of transmittal is signed by a person other than the registered holder of any original notes listed therein, such original notes must be endorsed or accompanied by appropriate bond powers and a proxy which authorizes such person to tender the original notes on behalf of the registered holder, in each case signed as the name of the registered holder or holders appears on the original notes.

If a letter of transmittal or any original notes or bond powers are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, such persons should so indicate when signing, and unless waived by us, evidence satisfactory to us of their authority so to act must be submitted with such letter of transmittal.

All questions as to the validity, form, eligibility, including time of receipt, and withdrawal of the tendered original notes will be determined by us in our sole discretion, which determination will be final and binding. We reserve the absolute right to reject any and all original notes not properly tendered or any original notes our acceptance of which, in the opinion of our counsel, would be unlawful. We also reserve the absolute right to waive any irregularities or defects as to the original notes. If we waive any condition of the notes for any note holder, we will waive such condition for all note holders. Our interpretation of the terms and conditions of the exchange offer, including the instructions in the letter of transmittal, will be final and binding on all parties. Unless waived, any

Table of Contents

defects or irregularities in connection with tenders of original notes must be cured within such time as we shall determine. None of us, the exchange agent or any other person shall be under any duty to give notification of defects or irregularities with respect to tenders of original notes, nor shall any of them incur any liability for failure to give such notification. Tenders of original notes will not be deemed to have been made until such irregularities have been cured or waived. Any original notes received by the exchange agent that are not properly tendered and as to which the defects or irregularities have not been cured or waived will be returned by the exchange agent to the tendering holders of original notes without cost to such holder, unless otherwise provided in the relevant letter of transmittal, promptly following the expiration date.

In addition, we reserve the absolute right in our sole discretion to:

•: purchase or make offers for any original notes that remain outstanding subsequent to the expiration date or, as set forth under "The Exchange Offer—Conditions," to terminate the exchange offer in accordance with the terms of the registration rights agreement; and
•: to the extent permitted by applicable law, purchase original notes in the open market, in privately negotiated transactions or otherwise.

The terms of any such purchases or offers may differ from the terms of the exchange offer.

By tendering, each holder will represent to us that, among other things:

•: such holder or other person is not our "affiliate," as defined under Rule 405 of the Securities Act, or, if such holder or other person is such an affiliate, will comply with the registration and prospectus delivery requirements of the Securities Act to the extent applicable,
•: the new notes acquired pursuant to the exchange offer are being obtained in the ordinary course of business of such holder or other person,
•: neither such holder or other person has any arrangement or understanding with any person to participate in the distribution of such new notes in violation of the Securities Act, and
•: if such holder is not a broker-dealer, neither such holder nor such other person is engaged in or intends to engage in a distribution of the new notes.

We understand that the exchange agent will make a request promptly after the date of this prospectus to establish accounts with respect to the original notes at The Depository Trust Company ("DTC") for the purpose of facilitating the exchange offer, and subject to the establishment of such accounts, any financial institution that is a participant in DTC's system may make book-entry delivery of original notes by causing DTC to transfer such original notes into the exchange agent's account with respect to the original notes in accordance with DTC's procedures for such transfer. Although delivery of the original notes may be effected through book-entry transfer into the exchange agent's account at DTC, a letter of transmittal properly completed and duly executed with any required signature guarantee, or an agent's message in lieu of a letter of transmittal, and all other required documents must in each case be transmitted to and received or confirmed by the exchange agent at its address set forth below on or prior to the expiration date, or, if the guaranteed delivery procedures described below are complied with, within the time period provided under such procedures. Delivery of documents to DTC does not constitute delivery to the exchange agent.

Guaranteed Delivery Procedures

Holders who wish to tender their original notes and

•: whose original notes are not immediately available; or

Table of Contents

•: who cannot deliver their original notes, the letter of transmittal or any other required documents to the exchange agent prior to 11:59 p.m., New York City time, on the expiration date of the exchange offer; or
•: who cannot complete the procedures for delivery by book-entry transfer prior to 11:59 p.m., New York City time, on the expiration date of the exchange offer,

may effect a tender if:

•: the tender is made by or through an "eligible guarantor institution";
•: prior to 11:59 p.m., New York City time, on the expiration date of the exchange offer, the exchange agent receives from such "eligible guarantor institution" a properly completed and duly executed Notice of Guaranteed Delivery, by facsimile transmission, mail or hand delivery, setting forth the name and address of the holder of the original notes, the certificate number or numbers of such original notes and the principal amount of original notes tendered, stating that the tender is being made thereby, and guaranteeing that, within three business days after the expiration date, a letter of transmittal, or facsimile thereof or agent's message in lieu of such letter of transmittal, together with the certificate(s)representing the original notes to be tendered in proper form for transfer and any other documents required by the letter of transmittal will be deposited by the eligible guarantor institution with the exchange agent; and
•: a properly completed and duly executed letter of transmittal (or facsimile thereof) together with the certificate(s) representing all tendered original notes in proper form for transfer or an agent's message in the case of delivery by book-entry transfer and all other documents required by the letter of transmittal are received by the exchange agent within three business days after the expiration date.

Withdrawal of Tenders

Except as otherwise provided in this prospectus, tenders of original notes may be withdrawn at any time prior to 11:59 p.m., New York City time, on the expiration date.

To withdraw a tender of original notes in the exchange offer, a written or facsimile transmission notice of withdrawal must be received by the exchange agent at its address set forth in this prospectus prior to 11:59 p.m., New York City time, on the expiration date. Any such notice of withdrawal must:

•: specify the name of the depositor, who is the person having deposited the original notes to be withdrawn;
•: identify the original notes to be withdrawn, including the certificate number or numbers and principal amount of such original notes or, in the case of original notes transferred by book-entry transfer, the name and number of the account at DTC to be credited;
•: be signed by the depositor in the same manner as the original signature on the letter of transmittal by which such original notes were tendered, including any required signature guarantees, or be accompanied by documents of transfer sufficient to have the trustee with respect to the original notes register the transfer of such original notes into the name of the depositor withdrawing the tender; and
•: specify the name in which any such original notes are to be registered, if different from that of the depositor.

Table of Contents

All questions as to the validity, form and eligibility, including time of receipt, of such withdrawal notices will be determined by us, and our determination shall be final and binding on all parties. Any original notes so withdrawn will be deemed not to have been validly tendered for purposes of the exchange offer and no new notes will be issued with respect to the original notes withdrawn unless the original notes so withdrawn are validly retendered. Any original notes which have been tendered but which are not accepted for exchange will be returned to its holder without cost to such holder promptly after withdrawal, rejection of tender or termination of the exchange offer. Properly withdrawn original notes may be retendered by following one of the procedures described above under "The Exchange Offer—Exchange Offer Procedures" at any time prior to the expiration date.

Conditions

Notwithstanding any other term of the exchange offer, we will not be required to accept for exchange, or exchange, any new notes for any original notes, and may terminate or amend the exchange offer before the expiration date, if:

•: in the opinion of our counsel, the exchange offer or any part thereof contemplated herein violates any applicable law or interpretation of the staff of the SEC;
•: any action or proceeding shall have been instituted in any court or by any governmental agency which might materially impair our ability to proceed with the exchange offer or any material adverse development shall have occurred in any such action or proceeding with respect to us;
•: any governmental approval has not been obtained, which approval we shall deem necessary for the consummation of the exchange offer as contemplated hereby;
•: any cessation of trading on any securities exchange, or any banking moratorium, shall have occurred, as a result of which we are unable to proceed with the exchange offer; or
•: a stop order shall have been issued by the SEC or any state securities authority suspending the effectiveness of the registration statement or proceedings shall have been initiated for that purpose.

If any of the foregoing conditions exist, we may, in our reasonable discretion:

•: refuse to accept any original notes and return all tendered original notes to the tendering holders;
•: extend the exchange offer and retain all original notes tendered prior to the expiration of the exchange offer, subject, however, to the rights of holders who tendered such original notes to withdraw their tendered original notes; or
•: waive such condition, if permissible, with respect to the exchange offer and accept all properly tendered original notes which have not been withdrawn. If such waiver constitutes a material change to the exchange offer, we will promptly disclose such waiver by means of a prospectus supplement that will be distributed to the holders, and we will extend the exchange offer, if necessary, so that at least five business days remain prior to the expiration date following the date of such prospectus supplement.

Exchange Agent

We have appointed Deutsche Bank Trust Company Americas as exchange agent for the exchange offer. Please direct questions and requests for assistance, requests for additional copies of this prospectus or of the letter of transmittal and requests for the notice of guaranteed delivery to Deutsche Bank Trust Company America addressed as follows:

By Mail, Overnight Courier or Hand Delivery:
Deutsche Bank Trust Company Americas
(US CTAS Operations)
5022 Gate Parkway
Suite 200
Jacksonville, FL 32256

By Facsimile:
(615) 866-3889
Attention: Reorganization Unit

To Confirm by Telephone or for Information:
(800) 735-7777

Deutsche Bank Trust Company Americas is the trustee under the indenture governing the original notes and the new notes.

Fees and Expenses

We will pay the expenses of soliciting original notes for exchange. The principal solicitation is being made by mail by Deutsche Bank Trust Company Americas as exchange agent. However, additional solicitations may be made by telephone, facsimile or in person by our officers and regular employees and our affiliates and by persons so engaged by the exchange agent.

We will pay Deutsche Bank Trust Company Americas as exchange agent reasonable and customary fees for its services and will reimburse it for its reasonable out-of-pocket expenses in connection therewith and pay other registration expenses, including fees and expenses of the trustee under the indenture, filing fees, blue sky fees and printing and distribution expenses.

We will pay all transfer taxes, if any, applicable to the exchange of the original notes in connection with the exchange offer. If, however, certificates representing the new notes or the original notes for principal amounts not tendered or accepted for exchange are to be delivered to, or are to be issued in the name of, any person other than the registered holder of the original notes tendered, or if tendered original notes are registered in the name of any person other than the person signing the letter of transmittal, or if a transfer tax is imposed for any reason other than the exchange of the original notes in this exchange offer, then the amount of any such transfer taxes, whether imposed on the registered holder or any other person, will be payable by the tendering holder.

Accounting Treatment

The new notes will be recorded at the same carrying value as the original notes as reflected in our accounting records on the date of exchange. Accordingly, no gain or loss for accounting purposes will be recognized by us. The expenses of the exchange offer and the unamortized expenses related to the issuance of the original notes will be amortized over the term of the new notes.

Table of Contents

Consequences of Failure to Exchange

Holders of original notes who are eligible to participate in the exchange offer but who do not tender their original notes will not have any further registration rights, and their original notes will continue to be subject to restrictions on transfer of the original notes as described in the legend on the original notes as a consequence of the issuance of the original notes under exemptions from, or in transactions not subject to, the registration requirements of the Securities Act and applicable state securities laws. In general, the original notes may not be offered or sold, unless registered under the Securities Act, except under an exemption from, or in a transaction not subject to, the Securities Act and applicable state securities laws.

Regulatory Approvals

We do not believe that the receipt of any material federal or state regulatory approval will be necessary in connection with the exchange offer, other than the effectiveness of the exchange offer registration statement under the Securities Act.

Other

Participation in the exchange offer is voluntary and holders of original notes should carefully consider whether to accept the terms and conditions of this exchange offer. Holders of the original notes are urged to consult their financial and tax advisors in making their own decisions on what action to take with respect to the exchange offer.

Neither our affiliates nor the affiliates of the guarantors have any interest, direct or indirect, in the exchange offer.

This exchange offer is intended to satisfy our obligations to register an exchange offer of the new notes for the original notes required by the registration rights agreement entered into in connection with the offering of the original notes. We will not receive any cash proceeds from the issuance of the new notes. In consideration for issuing the new notes, we will receive the outstanding original notes in like principal amount, the terms of which are identical in all material respects to the terms of the new notes, except as otherwise described herein. The original notes surrendered in exchange for the new notes will be retired and cancelled and cannot be reissued.

The gross proceeds from the sale of the original notes were approximately $289.67 million. The proceeds that we received from the sale of the original notes may be used to redeem up to $255.8 million of our 3.25% Convertible Senior Notes due 2026, which we refer to as the "3.25% convertible senior notes," on or after November 15, 2011. The remaining proceeds will be used for working capital and general corporate purposes, including possible acquisitions. Pending any such application of the proceeds, we may invest the net proceeds in short-term, interest-bearing instruments and other investment-grade securities.

(1): On December 8, 2010, we acquired ITC^DeltaCom, a provider of integrated communications services to customers in the southeastern U.S. The results of operations of ITC^DeltaCom have been included in our consolidated financial statements since the acquisition date.
(2): Operating costs and expenses for the years ended December 31, 2008, 2009 and 2010 include non-cash impairment charges of $78.7 million, $24.1 million and $1.7 million, respectively, related to goodwill and certain intangible assets of New Edge in our Business Services segment. During 2008 and 2009, we concluded the carrying value of these assets were impaired in conjunction with our annual tests of goodwill and intangible assets deemed to have indefinite lives. During 2010, we decided to re-brand the New Edge name as EarthLink Business and wrote off our New Edge trade name.
(3): Operating costs and expenses for the years ended December 31, 2008, 2009 and 2010 and the three months ended March 31, 2010 and 2011 include restructuring and acquisition-related costs of $9.1 million, $5.6 million and $22.4 million and $1.4 million and $4.5 million, respectively.
(4): During the years ended December 31, 2008 and 2009, we recorded income tax benefits in the Statement of Operations of approximately $56.1 million and $198.8 million, respectively, from releases of our valuation allowance related to deferred tax assets. These deferred tax assets related primarily to net operating loss carryforwards which we determined we will more likely than not be able to utilize due to the generation of sufficient taxable income in the future.
(5): In November 2007, management concluded that the municipal wireless broadband operations were no longer consistent with our strategic direction and our Board of Directors authorized management to pursue the divestiture of our municipal wireless broadband assets. As a result of that decision, we classified the municipal wireless broadband assets as held for sale and presented the municipal wireless broadband operations as discontinued operations for all periods presented.
(6): Includes the carrying amount of the 3.25% convertible senior notes, which was $198.0 million, $208.3 million, $219.7 million, $232.2 million and $243.1 million as of December 31, 2006, 2007, 2008, 2009 and 2010, respectively, and $232.8 million and $246.6 million as of March 31, 2010 and 2011, respectively. During November 2006, we issued $258.8 million aggregate principal amount of 3.25% convertible senior notes in a registered offering. The 3.25% convertible senior notes are convertible on October 15, 2011 and upon certain events. We have the option to redeem the 3.25% convertible senior notes, in whole or in part, for cash, on or after November 15, 2011, provided that we have made at least ten semi-annual interest payments. In addition, the holders may require us to purchase all or a portion of the 3.25% convertible senior notes on each of November 15, 2011, November 15, 2016 and November 15, 2021. During 2009, we began paying quarterly cash dividends on our common stock. This requires an adjustment to the conversion rate for the 3.25% convertible senior notes and opens a conversion period for holders. As a result, the 3.25% convertible senior notes were classified as a current liability in our Consolidated Balance Sheets as

of December 31, 2009. On November 15, 2011, holders of the 3.25% convertible senior notes have the right under the governing indenture to require the Company to repurchase the 3.25% convertible senior notes. As a result, we classified the 3.25% convertible senior notes as a current liability in the Consolidated Balance Sheet as of December 31, 2010 and March 31, 2011.

As of December 31, 2010 and March 31, 2011, also include the carrying amount of the ITC^DeltaCom notes assumed in our acquisition of ITC^DeltaCom in December 2010, which was $351.3 million as of December 31, 2010 and $350.0 million as of March 31, 2011. The ITC^DeltaCom notes will mature on April 1, 2016. See "Description of Certain Indebtedness."

EARTHLINK, INC.
UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The following unaudited pro forma condensed combined financial statements are based on the historical financial statements of EarthLink, Inc. ("EarthLink"), One Communications Corp. ("One Communications") and ITC^DeltaCom, Inc. ("ITC^DeltaCom") after giving effect to the following:

•: EarthLink's acquisition of One Communications on April 1, 2011;
•: EarthLink's acquisition of ITC^DeltaCom on December 8, 2010;
•: the issuance of $300.0 million aggregate principal amount of 8.875% senior secured notes due 2019 on May 17, 2011 (the "Notes");
•: the use of approximately $255.8 million of the net proceeds of the Notes to redeem EarthLink's 3.25% convertible senior notes; and
•: the application of the assumptions, reclassifications and adjustments described in the accompanying notes to the unaudited pro forma condensed combined financial statements.

The unaudited pro forma condensed combined balance sheet as of March 31, 2011 is presented as if the acquisition of One Communications, the issuance of the Notes and the use of approximately $255.8 million of the net proceeds of the notes offering to redeem EarthLink's 3.25% convertible senior notes had occurred on March 31, 2011. The unaudited pro forma condensed combined statements of operations for the three months ended March 31, 2011 and for the fiscal year ended December 31, 2010 are presented as if the acquisition of One Communications, the issuance of the Notes and the use of approximately $255.8 million of the net proceeds of the Notes offering to redeem EarthLink's 3.25% convertible senior notes had occurred on January 1, 2010. The unaudited pro forma condensed combined statement of operations for the fiscal year ended December 31, 2010 is also presented as if the acquisition of ITC^DeltaCom had occurred on January 1, 2010.

The historical consolidated financial information has been adjusted to give effect to pro forma events that are (i) directly attributable to the transactions, (ii) factually supportable and (iii) with respect to the statement of operations, expected to have a continuing impact on the combined results. The unaudited pro forma condensed combined financial statements should be read in conjunction with the historical consolidated financial statements and accompanying notes of EarthLink, One Communications and ITC^DeltaCom included elsewhere in and incorporated by reference into this document.

The unaudited pro forma condensed combined financial statements have been presented for informational purposes only. The unaudited pro forma condensed combined financial statements are not intended to represent or be indicative of what the combined company's results of operations or financial position that would have reported had the acquisition been completed as of the dates presented, and should not be taken as a representation of the combined company's future consolidated results of operations or financial position. The unaudited pro forma condensed combined financial statements do not reflect any operating efficiencies and cost savings that may be achieved with respect to the combined companies or the costs necessary to achieve these cost savings and operating synergies.

The unaudited pro forma condensed combined financial statements have been prepared using the acquisition method of accounting. The preliminary allocation of the purchase price used in the unaudited pro forma condensed combined financial statements is based upon preliminary estimates. These preliminary estimates and assumptions are subject to change during the measurement period (up to one year from the acquisition date) as EarthLink finalizes the valuations of the net tangible and intangible assets acquired in connection with the acquisition.

financial statements.

Table of Contents

1. Basis of Presentation

The unaudited pro forma condensed combined financial statements are based on the historical financial statements of EarthLink, Inc. ("EarthLink"), One Communications Corp. ("One Communications") and ITC^DeltaCom, Inc. ("ITC^DeltaCom") after giving effect to: (1) EarthLink's acquisition of One Communications on April 1, 2011; (2) EarthLink's acquisition of ITC^DeltaCom on December 8, 2010; (3) the issuance of $300.0 million aggregate principal amount of 8.875% senior secured notes due 2019 on May 17, 2011 (the "Notes"); (4) the use of approximately $255.8 million of the net proceeds of the Notes to redeem EarthLink's 3.25% convertible senior notes; and (5) application of the assumptions, reclassifications and adjustments described in the accompanying notes to the unaudited pro forma condensed combined financial statements.

The unaudited pro forma condensed combined balance sheet as of March 31, 2011 is presented as if the acquisition of One Communications, the issuance of Notes and the use of approximately $255.8 million of the net proceeds of that offering to redeem EarthLink's 3.25% convertible senior notes had occurred on March 31, 2011. The unaudited pro forma condensed combined statements of operations for the three months ended March 31, 2011 and for the fiscal year ended December 31, 2010 are presented as if the acquisition of One Communications, the issuance of Notes and the use of approximately $255.8 million of the net proceeds of the Notes offering to redeem EarthLink's 3.25% convertible senior notes had occurred on January 1, 2010. The unaudited pro forma condensed combined statement of operations for the fiscal year ended December 31, 2010 is also presented as if the acquisition of ITC^DeltaCom had occurred on January 1, 2010.

The unaudited pro forma condensed combined financial statements should be read in conjunction with the historical consolidated financial statements and accompanying notes of EarthLink, One Communications and ITC^DeltaCom included elsewhere in and incorporated by reference into this prospectus.

The unaudited pro forma condensed combined financial statements were prepared using the acquisition method of accounting. As such, identifiable assets acquired and liabilities assumed are recognized at fair value as of the acquisition date. Goodwill as of the acquisition date is measured as the excess of consideration transferred and the net amounts of the identifiable assets acquired and the liabilities assumed.

EarthLink has made significant assumptions and estimates in determining the preliminary estimated purchase price and the preliminary allocation of the estimated purchase price in the unaudited pro forma condensed combined financial statements. These preliminary estimates and assumptions are subject to change during the measurement period (up to one year from the acquisition date) as EarthLink finalizes the valuations of the intangible assets and net tangible assets and resulting goodwill. In particular, the final valuations of identifiable intangible and net tangible assets may change significantly from EarthLink's preliminary estimates. These changes could result in material variances between EarthLink's future financial results and the amounts presented in these unaudited pro forma condensed combined financial statements, including variances in fair values recorded, as well as expenses and cash flows associated with these items.

2. Description of Transactions

One Communications

On April 1, 2011, EarthLink completed its acquisition of One Communications, a privately-held, multi-regional integrated telecommunications solutions provider serving customers in the Northeast, Mid-Atlantic and Upper Midwest. EarthLink acquired 100% of One Communications in a merger transaction with One Communications surviving as an indirect wholly-owned subsidiary of EarthLink. One Communications stockholders had the right to elect to receive the net merger consideration in the form of cash or EarthLink common stock.

Pursuant to the terms of the merger agreement, the aggregate merger consideration for One Communications was $370.0 million, which included repayment of net indebtedness of approximately $282.1 million and $40.6 million of other liabilities and certain working capital and other adjustments as provided in the merger agreement. In addition, $21.0 million of the aggregate merger consideration was deposited in an escrow account to secure potential post-closing adjustments to the aggregate consideration relating to working capital and other similar adjustments, indemnification obligations and post-closing One Communications employment-related obligations.

The resulting preliminary fair value of consideration transferred was $47.4 million, which consisted of $23.8 million in cash paid to acquire the outstanding common stock of One Communications and $23.6 million for the issuance of 3.0 million shares of EarthLink common stock. The assets acquired and liabilities assumed of One Communications will be recognized at their acquisition date fair values. The allocation of the consideration transferred to the assets acquired and liabilities assumed of One Communications (and the related estimated lives of depreciable tangible and identifiable intangible assets) will require a significant amount of judgment.

The following is a preliminary allocation of the consideration transferred based on currently available information. Such final identification of all the intangible assets acquired and the purchase price allocation may be significantly different than that reflected below (dollars in thousands).



Acquired Assets:
Cash and cash equivalents		$	11,158
Property and equipment			145,840
Goodwill			148,318
Intangible assets			176,800
Other assets			83,113

	Total assets		565,229

Assumed Liabilities:
Debt			(266,275	)
Deferred revenue			(11,379	)
Deferred tax liability, net			(64,860	)
Other liabilities			(175,288	)

	Total liabilities		(517,802	)

	Total consideration	$	47,427

Table of Contents

The following table summarizes the preliminary components of intangible assets acquired in connection with the One Communications acquisition (in thousands):

		Fair Value		Useful Life

Customer relationships		$	160,900	5 Years
Developed technology			12,000	3 Years
Trade name			3,900	3 Years

	Total intangible assets	$	176,800

EarthLink has evaluated and continues to evaluate pre-acquisition contingencies relating to One Communications that existed as of the acquisition date. EarthLink continues to gather information for and evaluate substantially all pre-acquisition contingencies that it has assumed from One Communications. If EarthLink makes changes to the amounts recorded or identifies additional pre-acquisition contingencies during the remainder of the measurement period, such amounts recorded will be included in the purchase price allocation during the measurement period and, subsequently, in EarthLink's results of operations.

ITC^DeltaCom

On December 8, 2010, EarthLink acquired ITC^DeltaCom, a provider of integrated communications services to customers in the southeastern U.S., at a price of $3.00 per share. EarthLink acquired 100% of ITC^DeltaCom in a merger transaction with ITC^DeltaCom surviving as a wholly-owned subsidiary of EarthLink.

The fair value of consideration transferred was $253.8 million, which consisted of $251.4 million in cash paid to acquire the outstanding common stock of ITC^DeltaCom and $2.3 million for the fair value of restricted stock units assumed and converted. In allocating the consideration transferred based on estimated fair values, EarthLink recorded $170.1 million of goodwill, $131.2 million of identifiable intangible assets, $200.5 million of property and equipment, $351.2 million of long-term debt and $103.2 million of other net assets. EarthLink allocated the consideration transferred to the tangible assets, liabilities and intangible assets acquired based on their estimated fair values. The excess of the consideration transferred over those fair values was recorded as goodwill.

3. Reclassifications

Certain reclassifications have been made to conform One Communications' historical amounts to EarthLink's presentation. These reclassifications consisted of the following:

•: One Communications due from related parties of $0.3 million as of March 31, 2011 was reclassified as other current assets.
•: One Communications long-term deferred revenue of $10.4 million as of March 31, 2011 was reclassified as other long-term liabilities.
•: One Communications (gain) loss on disposition of property and equipment of $17,000 and ($639,000) during the three months ended March 31, 2011 and the year ended December 31, 2010, respectively, was reclassified as selling, general and administrative expenses.
•: One Communications other operating income of $25,000 and $333,000 during the three months ended March 31, 2011 and the year ended December 31, 2010, respectively, was reclassified as selling, general and administrative expenses.

Table of Contents

•: One Communications interest expense and interest income totaling $12.0 million and $54.8 million during the three months ended March 31, 2011 and the year ended December 31, 2010, respectively, were reclassified as interest expense and other, net.

4. Pro Forma Adjustments

The pro forma adjustments included in the unaudited pro forma condensed combined consolidated financial statements are as follows:

Purchase Accounting Adjustments

(a): To record the following adjustments to cash and cash equivalents (in thousands):


Cash paid for One Communications		$	23,828
Cash paid to repay debt			275,848
Cash paid for other One Communications obligations			36,788

	Total adjustments to cash and cash equivalents	$	336,464

(b): To record the difference between the preliminary estimated fair value and the historical amount of One Communications' accounts receivable.

Increase in deferred tax assets, current		$	3,754
Increase in deferred tax liabilities, noncurrent			(68,614	)

	Net increase in deferred income tax liabilities	$	(64,860	)

The preliminary net increase in deferred income tax liabilities is primarily attributable to acquired deferred tax liabilities associated with certain intangible assets acquired, which were partially offset by EarthLink's ability to utilize certain net operating loss carryforwards from One Communications.

(e): To record the difference between the preliminary estimated fair value and the historical amount of One Communications' property and equipment.
(f): To record the difference between the preliminary estimated fair value and the historical amount of One Communications' intangible assets (in thousands):

		Historical Amounts, Net		Preliminary Fair Values		Increase

Customer relationships		$	21,441	$	160,900	$	139,459
Developed technology			278		12,000		11,722

Goodwill represents the excess of the purchase price of an acquired business over the fair value of the underlying net tangible and intangible assets. Goodwill is not amortized, but rather is tested for impairment at least annually. In the event that EarthLink determines that the value of goodwill has become impaired, EarthLink will incur an accounting charge for the amount of impairment during the fiscal quarter in which such determination is made.

(h): To record the difference between the preliminary estimated fair value and the historical amount of favorable and unfavorable indefeasible right-to-use agreements.
(i): To record repayment of One Communications debt, including a $22.8 million decrease to the current portion of debt (including the One Communications' interest rate swap agreement), a $246.9 million decrease to long-term debt and a $6.1 million decrease in accrued interest. Also to record the write-off of $7.0 million of One Communications' historical unamortized debt issuance costs included in other long-term assets.

(r)

To record the pro forma tax impact at weighted average estimated income tax rates applicable to the jurisdictions in which the pro forma adjustments are expected to be recorded. The pro forma combined provision for income taxes does not reflect the amounts that would have resulted had EarthLink, One Communications and ITC^DeltaCom filed consolidated income tax returns during the periods presented.

(s)

To record the estimated stock-based compensation expense related to ITC^DeltaCom restricted stock units assumed in connection with the acquisition as they relate to postcombination services using the straight-line amortization method over the remaining requisite service periods and to remove historical stock-based compensation expense.

DESCRIPTION OF OTHER INDEBTEDNESS

The following summarizes the principal terms of our material debt agreements.

Senior Secured Revolving Credit Facility

On May 20, 2011, the Company entered into a credit agreement (the "Credit Agreement") with Regions Bank, as administrative and collateral agent, and the other lenders party thereto, providing for a new senior secured revolving credit facility with aggregate revolving commitments of $150 million.

This new senior secured revolving credit facility replaces the Company's existing $30 million senior secured credit facility and consists of the following:

•: a four year revolving credit facility under which the Company may obtain from time to time revolving loans of up to an aggregate principal amount of $150 million outstanding at any time (which may be increased up to $50 million with certain additional commitments from the current lenders or other financial institutions acceptable to the agent and the satisfaction of certain other customary conditions to such increase contained in the Credit Agreement);
•: a $30 million sublimit for borrowings by ITC^DeltaCom, Inc. ("ITC^DeltaCom"), a wholly-owned subsidiary of the Company, once it is joined to the Credit Agreement as a co-borrower (as discussed below);
•: a $30 million sublimit for the issuance of standby letters of credit; and
•: a $10 million sublimit for swingline loans.

As of the date of this filing, no loans are outstanding under the new credit facility.

The Company is the borrower (subject to ITC^DeltaCom becoming a co-borrower as discussed below) under the senior secured revolving credit facility. All obligations of the borrower(s) under the facility are guaranteed by each of the Company's existing and future direct and indirect domestic subsidiaries, other than (i) certain dormant, inactive or otherwise immaterial subsidiaries and (ii) until such time as ITC^DeltaCom and its subsidiaries have completed certain repayments or refinancing of ITC^DeltaCom's 10.5% Senior Secured Notes due 2016 (the "ITC^DeltaCom notes"), ITC^DeltaCom and its subsidiaries. ITC^DeltaCom and its subsidiaries are not required to guarantee the Company's senior secured credit facility until either (a) ITC^DeltaCom has repaid or refinanced the ITC^DeltaCom notes to the extent that such secured guarantee is permitted by the terms of the indenture governing the ITC^DeltaCom notes, or (b) the ITC^DeltaCom notes are repaid in full. At such time as ITC^DeltaCom becomes a guarantor of the credit facility, it will also become a co-borrower under the credit agreement to the extent of its $30 million sublimit discussed above. Following such guarantee and joinder as a co-borrower, the Company and its subsidiary guarantors will also guarantee all obligations of ITC^DeltaCom and its subsidiaries under the senior secured revolving credit facility.

The obligations of the Company, the subsidiary guarantors, and ITC^DeltaCom (once joined as a co-borrower) under the credit facility, as well as obligations under any treasury management, interest protection or other hedging arrangements entered into with a lender (or affiliate thereof), are secured by first priority (subject to certain liens permitted by the Credit Agreement) liens on and security interests in, (i) substantially all of the Company's and the subsidiary guarantors' present and future personal property assets (subject to certain exclusions set forth in the Credit Agreement), (ii) certain of the Company's and the subsidiary guarantors' present and future real estate owned in fee simple that is required by the Credit Agreement to be mortgaged, (iii) all present and future shares of the capital stock of the Company's and the subsidiary guarantors' present and future subsidiaries (excluding (a) the stock of subsidiaries for which regulatory approval of such pledge has not been obtained, (b) the stock of ITC^DeltaCom's subsidiaries until such time as ITC^DeltaCom becomes a guarantor as provided

Table of Contents

above, and (c) any stock in excess of 66% of the voting stock of non-U.S. subsidiaries), and (iv) all proceeds and products of the foregoing property and assets.

The Company (and ITC^DeltaCom, once it is joined as a co-borrower) may use the proceeds of loans under the senior secured revolving credit facility for working capital, permitted acquisitions, capital expenditures and general corporate purposes, including the refinancing of existing indebtedness, in each case not in contradiction of applicable laws. Letters of credit issued under the credit facility may be used to support operating needs of the Company and its subsidiaries.

The final maturity date of the senior secured revolving credit facility is May 20, 2015. The Company may prepay the senior secured revolving credit facility in whole or in part at any time without premium or penalty, subject to reimbursement of the lenders' breakage and redeployment costs in the case of prepayment of LIBOR borrowings. The Company may irrevocably reduce or terminate the unutilized portion of the senior secured revolving credit facility at any time without penalty.

Subject to the terms of the Credit Agreement, the Company (and ITC^DeltaCom, once it is joined as a co-borrower), at its option, may borrow at either the LIBOR rate or the base rate (each as defined in the Credit Agreement), in each case plus an applicable margin determined based on the Company's consolidated leverage ratio. Each swingline loan shall bear interest at swingline rate established by the swingline lender and accepted by the Company. For LIBOR loans, the Company (and ITC^DeltaCom, once it is joined as a co-borrower, as applicable) may select interest periods of one, two, three or six months, subject to availability. Interest shall be payable at the end of the selected interest period for LIBOR loans, but no less frequently than quarterly, and at the end of each calendar quarter, for base rate loans. During the continuance of any default under the Credit Agreement, the applicable interest rate or letter of credit fee may be increased by 2% per annum.

The Credit Agreement contains representations and warranties, covenants, and events of default with respect to the Company and its subsidiaries that are customarily applicable to senior secured credit facilities. Notwithstanding the foregoing, such covenants will not apply to ITC^DeltaCom and its subsidiaries until the earlier of (i) the repayment or refinancing in full of the ITC^DeltaCom notes or (ii) the date ITC^DeltaCom and its U.S. subsidiaries become guarantors of the senior secured revolving credit facility (as discussed above). The negative covenants contained in the Credit Agreement include restrictions on the ability of the Company and its subsidiaries to, among other things, incur additional indebtedness, incur liens on assets, engage in certain mergers, acquisitions or divestitures, pay dividends or make other distributions, voluntarily prepay certain other indebtedness (including certain prepayments of the Company's existing notes and the ITC^DeltaCom notes), enter into transactions with affiliates, make investments, and change the nature of their businesses, and amend the terms of certain other indebtedness (including the Company's existing notes and the ITC^DeltaCom notes), in each case subject to certain exceptions set forth in the Credit Agreement,

Additionally, the Credit Agreement requires the Company to maintain a maximum consolidated leverage ratio (the ratio of Funded Debt, as defined in the Credit Agreement, to EBITDA) of 3.5 to 1.0 and a minimum consolidated interest coverage ratio (the ratio of EBITDA (less capital expenditures) to interest expense) of 2.0 to 1.0.

ITC^DeltaCom Notes

As of the date of this prospectus, ITC^DeltaCom, our wholly-owned subsidiary, has outstanding $324.8 million principal amount of ITC^DeltaCom notes.

The 10.5% senior secured notes accrue interest at a rate of 10.5% per year. Interest on the ITC^DeltaCom notes is payable semi-annually in cash in arrears on April 1 and October 1 of each year, commencing on October 1, 2010. The ITC^DeltaCom notes will mature on April 1, 2016.

Table of Contents

We may redeem some or all of the ITC^DeltaCom notes, at any time before April 1, 2013, at a redemption price equal to 100% of their principal amount plus a "make-whole" premium. We may redeem some or all of the ITC^DeltaCom notes, at any time on or after April 1, 2013, at specified redemption prices declining from 105.250% to 100% of their principal amount. In addition, before April 1, 2013, we may redeem up to 35% of the aggregate principal amount of the ITC^DeltaCom notes at a redemption price equal to 110.5% of their principal amount with the net proceeds of certain equity offerings. During any 12-month period before April 1, 2013, we may redeem up to 10% of the aggregate principal amount of the ITC^DeltaCom notes at a redemption price equal to 103% of their principal amount. If ITC^DeltaCom (1) sells certain of its assets and does not either (a) apply the net sale proceeds to repay indebtedness under the ITC^DeltaCom notes, or other indebtedness secured on a first-priority basis or (b) reinvest the net sale proceeds in its business, or (2) experiences a change of control, we may be required to offer to purchase ITC^DeltaCom notes from holders at 100% of their principal amount, in the case of a sale of assets, or 101% of their principal amount, in the case of a change of control. We would be required to pay accrued and unpaid interest, if any, on the ITC^DeltaCom notes redeemed or purchased in each of the foregoing events of redemption or purchase.

Repayment of the ITC^DeltaCom notes may be accelerated upon the occurrence of events of defaults specified in the indenture governing the ITC^DeltaCom notes.

The ITC^DeltaCom notes are general senior obligations and rank equally in right of payment with all of ITC^DeltaCom's existing and future senior indebtedness. The ITC^DeltaCom notes are secured on a first-priority basis, along with any futurepari passu secured obligations, subject to specified exceptions and permitted liens, by substantially all of ITC^DeltaCom's assets and the assets of its subsidiaries that are deemed to be restricted subsidiaries under the indenture governing ITC^DeltaCom notes. The ITC^DeltaCom notes are guaranteed on a senior secured basis by each of ITC^DeltaCom's domestic restricted subsidiaries on the initial issue date of the ITC^DeltaCom notes and will be guaranteed on a senior secured basis by each of ITC^DeltaCom's future domestic restricted subsidiaries, other than certain excluded subsidiaries, and any foreign restricted subsidiary that guarantees any indebtedness or any domestic restricted subsidiary. The guarantees are the subsidiary guarantors' general senior obligations and rank equally in right of payment with all of the subsidiary guarantors' existing and future senior indebtedness. The ITC^DeltaCom notes are not guaranteed by EarthLink, Inc. or our other subsidiaries, other than the ITC^DeltaCom subsidiaries described above.

The indenture that governs the ITC^DeltaCom notes contains covenants that, among other things, limit ITC^DeltaCom's ability, and the ability of its restricted subsidiaries, to incur additional indebtedness, create liens, pay dividends on, redeem or repurchase its capital stock, make investments or repay subordinated indebtedness, engage in sale-leaseback transactions, enter into transactions with affiliates, sell assets, create restrictions on dividends and other payments from its subsidiaries, issue or sell stock of subsidiaries and engage in mergers and consolidations. All of the covenants are subject to a number of important qualifications and exceptions under the indenture governing the ITC^DeltaCom notes; that indenture does not contain any financial maintenance covenants.

3.25% Convertible Senior Notes

As of the date of this prospectus, we have outstanding $255.8 million principal amount of 3.25% Convertible Senior Notes due 2026, which we refer to as the "3.25% convertible senior notes" in this prospectus.

The 3.25% convertible senior notes bear interest at 3.25% per year on the principal amount of the 3.25% convertible senior notes until November 15, 2011, and 3.50% interest per year on the principal

Table of Contents

amount of the 3.25% convertible senior notes thereafter, payable semi-annually in May and November of each year. The 3.25% convertible senior notes rank as our senior unsecured obligations.

The 3.25% convertible senior notes are payable with cash and, if applicable, are convertible into shares of our common stock. The initial conversion rate was 109.6491 shares per $1,000 principal amount of 3.25% convertible senior notes (which represented an initial conversion price of approximately $9.12 per share). As a result of our cash dividend payments, the conversion rate has been adjusted and was 121.9549 shares per $1,000 principal amount of 3.25% convertible senior notes as of March 31, 2011 (which represents a conversion price of approximately $8.20 per share), subject to further adjustment. Upon conversion, a holder will receive cash up to the principal amount of the 3.25% convertible senior notes and, at our option, cash, or shares of our common stock or a combination of cash and shares of common stock for the remainder, if any, of the conversion obligation. The conversion obligation is based on the sum of the "daily settlement amounts" for the 20 consecutive trading days that begin on, and include, the second trading day after the day the 3.25% convertible senior notes are surrendered for conversion. The 3.25% convertible senior notes will be convertible only in the following circumstances: (1) during any calendar quarter after the calendar quarter ending December 31, 2006 (and only during such calendar quarter), if the closing sale price of our common stock for each of 20 or more trading days in a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter exceeds 130% of the conversion price in effect on the last trading day of the immediately preceding calendar quarter; (2) during the five consecutive business days immediately after any five consecutive trading day period in which the average trading price per $1,000 principal amount of 3.25% convertible senior notes was equal to or less than 98% of the average conversion value of the 3.25% convertible senior notes during the note measurement period; (3) upon the occurrence of specified corporate transactions, including the payment of dividends in certain circumstances; (4) if we have called the 3.25% convertible senior notes for redemption; and (5) at any time from, and including, October 15, 2011 to, and including, November 15, 2011 and at any time on or after November 15, 2024. We have the option to redeem the 3.25% convertible senior notes, in whole or in part, for cash, on or after November 15, 2011, provided that we have made at least ten semi-annual interest payments. In addition, the holders may require us to purchase all or a portion of their 3.25% convertible senior notes on each of November 15, 2011, November 15, 2016 and November 15, 2021.

The 3.25% convertible senior notes are our senior unsecured obligations and rank equally in right of payment with all of our existing and future senior unsecured indebtedness (including the notes offered hereby), and junior to any of our existing and future secured indebtedness to the extent of the security therefor. The notes are not guaranteed by our subsidiaries or joint ventures, and accordingly are effectively subordinated to the indebtedness and other liabilities of our subsidiaries and joint ventures (including trade payables).

We may use up to $255.8 million of the proceeds of original notes offering to redeem our 3.25% convertible senior notes on or after November 15, 2011.

The references to the "Company" in this description refer only to EarthLink, Inc. and not to any of its Subsidiaries. In this section, references to the "Notes" or "notes" are references to the outstanding 8.875% Senior Notes due 2019 and the new exchange 8.875% Senior Notes due 2019 offered hereby, collectively.

The Company originally issued the Notes under the Indenture in an offering not requiring registration under the Securities Act.

The following summary of certain provisions of the Indenture does not purport to be complete and is subject to, and is qualified in its entirety by reference to, all the provisions of the Indenture, including the definitions of certain terms in the Indenture, which provisions are made a part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"). Copies of the Indenture are available upon request from the Company. Whenever particular defined terms of the Indenture not defined herein are referred to, such defined terms are incorporated herein by reference. For definitions of certain capitalized terms used in the following summary, see "—Certain Definitions."

Brief Description of Notes and Guarantees

The Notes:

•: are general senior unsecured obligations of the Company;
•: rank equally in right of payment with all existing and future Senior Indebtedness of the Company, but are effectively subordinated to all of the Company's existing and future secured Indebtedness to the extent of the value of the collateral that secures such Indebtedness;
•: are senior in right of payment to all future Indebtedness of the Company that is subordinated in right of payment to the Notes;
•: are unconditionally guaranteed, jointly and severally, by each Subsidiary Guarantor; and
•: are structurally subordinated to any existing and future Indebtedness and other liabilities of Subsidiaries that are not Subsidiary Guarantors.

Each Subsidiary Guarantee of a Subsidiary Guarantor:

•: is a general senior unsecured obligation of such Subsidiary Guarantor;
•: ranks equally in right of payment with all existing and future Senior Indebtedness of such Subsidiary Guarantor, but is effectively subordinated to all of such Subsidiary Guarantor's secured Indebtedness to the extent of the value of the collateral that secures such Indebtedness;
•: is senior in right of payment to all existing and future Indebtedness of such Subsidiary Guarantor that is subordinated in right of payment to its Subsidiary Guarantee; and
•: is structurally subordinated to any existing and future Indebtedness and other liabilities of Subsidiaries of such Subsidiary Guarantor that are not also Subsidiary Guarantors.

As of March 31, 2011, after giving pro forma effect to the original notes offering, the use of the net proceeds of the notes offering, the consummation of the Acquisitions and our entry into the senior secured revolving credit facility:

•: the Company and its Subsidiaries would have had $659.29 million of Indebtedness outstanding, of which approximately $369.2 million would have been senior secured Indebtedness;

Table of Contents

•: the Company would have had an additional $150 million of unutilized capacity under its senior secured revolving credit facility; and
•: the Company's Subsidiaries that are not Subsidiary Guarantors would have had $458.4 million of Indebtedness and other liabilities outstanding.

On a pro forma basis after giving effect to the original notes offering, the use of the net proceeds of the notes offering and the consummation of the acquisition of One Communications, the Company's Subsidiaries that are not Subsidiary Guarantors would have accounted for:

•: $441.4 million (or 28%) of the Company's consolidated revenues and $24.3 million (or 33%) of the Company's consolidated net loss, in each case for the fiscal year ended December 31, 2010; and
•: $625.8 million (or 36%) of the Company's consolidated total assets and $441.2 million (or 46%) of the Company's consolidated total liabilities, in each case as of December 31, 2010.

Principal, Maturity and Interest

The Company issued $300,000,000 aggregate principal amount of the original notes on May 17, 2011. The Notes will mature on May 15, 2019.

Interest on the Notes accrues at a rate of 8.875% per annum from the Closing Date or from the most recent interest payment date to which interest had been paid or provided for. Interest on the Notes is payable semi-annually (to holders of record at the close of business on the May 1 or November 1 immediately preceding the interest payment date) on May 15 and November 15 of each year, beginning on November 15, 2011. Interest on the Notes is computed on the basis of a 360-day year of twelve 30-day months. As described under "The Exchange Offer—Additional Interest in Certain Circumstances" and "—Events of Default," the Company may be required to pay additional interest under certain circumstances. All references in the Indenture, in any context, to any interest payable on or with respect to the Notes shall be deemed to include any additional interest payable under such circumstances.

Principal of, premium, if any, and interest on the Notes is payable, and the Notes may be exchanged or transferred, at the office or agency of the Company in the Borough of Manhattan, The City of New York, or at the corporate trust office of the Trustee,provided,however, that, at the Company's option, payment of interest may be made by check mailed to the holders at their addresses as they appear in the security register maintained for the Notes.

The Notes were originally issued only in fully registered form, without coupons, in denominations of $2,000 of principal amount and any integral multiple of $1,000 in excess thereof. For additional information, see "—Book-Entry; Delivery and Form." No service charge will be made for any registration of transfer or exchange of Notes, but the Company may require payment of a fee to cover any transfer tax or other similar governmental charge payable in connection with a registration of transfer or exchange.

The Company may, subject to the covenants described below under the caption "—Certain Covenants—Incurrence of Indebtedness" and applicable law, issue additional Notes ("Additional Notes") under the Indenture. The Notes offered hereby and any Additional Notes subsequently issued would be treated as a single series for all purposes under the Indenture and would be considered "Notes" for purposes of the provisions of the Indenture summarized in this prospectus.

Subsidiary Guarantees

All obligations of the Company under the Indenture (including, without limitation, the Company's obligations to make payments of principal, interest and premium, if any) with respect to the Notes are guaranteed, jointly and severally, by each Subsidiary Guarantor for the ratable benefit of each holder of

Table of Contents

any outstanding Note from time to time. The Subsidiary Guarantors consists of the Company's Domestic Restricted Subsidiaries, other than certain excluded Domestic Restricted Subsidiaries as described below, and any Foreign Restricted Subsidiary that guarantees any Indebtedness of the Company or any of its Domestic Restricted Subsidiaries. All of the Company's Subsidiaries that guarantee the Initial Credit Agreement have initially guaranteed the Notes. Under the Indenture, any amount received by the Trustee through the enforcement of any Subsidiary Guarantee will be applied, following payment to the Trustee for all expenses incurred by it in connection with such enforcement and for any other fees, expenses and indemnities then owing to the Trustee, to all outstanding obligations in respect of principal, interest and premium, if any, then owing on the Notes.

If:

(1) the Company and its Restricted Subsidiaries have sold their ownership interest in a Subsidiary Guarantor such that it ceases to be a Subsidiary of any such entity, or

(2) a Subsidiary Guarantor has sold all or substantially all its assets,

in each case, in a transaction that complies with the Indenture, then such Subsidiary Guarantor will be released from all of its obligations under its Subsidiary Guarantee. For additional information, see "—Certain Covenants—Limitation on the Issuance and Sale of Capital Stock of Restricted Subsidiaries" and "—Consolidation, Merger and Sale of Assets."

If, at any time following the Closing Date, the Subsidiary Guarantors have paid, pursuant to enforcement by the Trustee of any Subsidiary Guarantees, the aggregate principal amount of, and accrued and unpaid interest and premium (if any) under, the Notes then outstanding and any other amounts due under the Indenture, then, at such time, all of the Subsidiary Guarantors will be discharged from their Subsidiary Guarantees and all other obligations under the Indenture.

The Indenture provides that the obligations of a Subsidiary Guarantor under its Subsidiary Guarantee will be limited to the maximum amount that will result in the obligations of such Subsidiary Guarantor under its Subsidiary Guarantee not to be deemed to constitute a fraudulent conveyance or fraudulent transfer under federal or state law. For additional information, see "Risk Factors—Risks Related to the Notes—A subsidiary guarantee could be voided if it constitutes a fraudulent transfer under U.S. bankruptcy or similar state law, which would prevent the holders of the notes from relying on that subsidiary to satisfy claims."

The following Subsidiaries are not required to guarantee the Notes:

(1) Subsidiaries, whether now existing or hereafter formed, for which proper governmental approvals for the incurrence of obligations under Subsidiary Guarantees have not been or cannot be obtained or which otherwise under applicable law may not incur obligations under Subsidiary Guarantees (provided that the Company shall use commercially reasonable efforts to cause such Subsidiaries to obtain all authorizations and consents of governmental authorities required in order for such Subsidiaries to guarantee the Notes at the earliest practicable date); for purposes of this paragraph, the requirement to use "commercially reasonable efforts" shall not be deemed to require the Company to make material payments in excess of normal fees and costs to or at the direction of governmental authorities or to change the manner in which it conducts its business in any respect that the management of the Company shall determine in good faith to be adverse or materially burdensome;

(2) at the Company's option, Subsidiaries, in the aggregate, whose assets are less than 5.0% of the consolidated total assets of the Company and its consolidated Subsidiaries (excluding, for so long as they are not required to guarantee the Notes, ITC^DeltaCom and its Subsidiaries) as shown on the most recent consolidated financial statements of the Company;

(3) for so long as (i) the ITC^DeltaCom Notes remain outstanding or (ii) the indenture governing the ITC^DeltaCom Notes contains covenants or other provisions that could prohibit

Table of Contents

ITC^DeltaCom or its subsidiaries from providing a guarantee of the Notes, ITC^DeltaCom and its subsidiaries; and

(4) any Receivables Subsidiary.

In addition, if the Company designates a Subsidiary Guarantor as an Unrestricted Subsidiary, which the Company may do under certain circumstances, the designated Subsidiary Guarantor will be released from all of its obligations under its Subsidiary Guarantee. As of the Closing Date, the Company had no Unrestricted Subsidiaries.

To the extent that Subsidiaries of the Company are not Subsidiary Guarantors, claims of creditors of such Subsidiaries, including trade creditors, and preferred stockholders, if any, of such Subsidiaries generally will have priority with respect to the assets and earnings of such Subsidiaries over the claims of creditors of the Company, including holders of the Notes. Therefore, the Notes will be effectively subordinated in right of payment to the claims of creditors, including trade creditors, and preferred stockholders, if any, of Subsidiaries of the Company formed or acquired in the future that are not Subsidiary Guarantors.

If any Note is to be redeemed in part, the notice of redemption relating to that Note will state the portion of the principal amount of the Note to be redeemed. A new Note in principal amount equal to the unredeemed portion of the Note will be issued in the name of the holder upon cancellation of the original Note.

No Sinking Fund

There will be no sinking fund payments for the Notes.

Limitation on Liens

The Company will not, and will not permit any Restricted Subsidiary to, create, incur, assume or suffer to exist any Lien on any of its assets or properties of any character (including, without limitation, licenses), or any shares of Capital Stock or Indebtedness of any Restricted Subsidiary, except Permitted Liens.

Limitation on Sale-Leaseback Transactions

The Company will not, and will not permit any Restricted Subsidiary to, enter into any sale-leaseback transaction involving any of its assets or properties whether now owned or hereafter acquired, whereby the Company or a Restricted Subsidiary sells or transfers such assets or properties and then or thereafter leases such assets or properties or any part thereof or any other assets or properties which the Company or such Restricted Subsidiary, as the case may be, intends to use for substantially the same purpose or purposes as the assets or properties sold or transferred.

The foregoing restriction shall not apply to any sale-leaseback transaction if:

(a) (1) the Company or such Restricted Subsidiary would be entitled to (a) incur Indebtedness in an amount equal to the Attributable Debt with respect to transaction pursuant to the covenant described under "—Limitation on Indebtedness" and (b) create a Lien on such property securing such Attributable Debt pursuant to the "Limitation on Liens" covenant; and

Table of Contents

are by their terms subordinated to the Notes or any Note Guarantee) that are assumed by the transferee of any such assets pursuant to a customary assumption or similar agreement;

(b) any securities, notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are converted by the Company or such Restricted Subsidiary into cash or Temporary Cash Investments within 180 days of receipt thereof, to the extent of the cash or Temporary Cash Investments received in that conversion; and

Within 12 months after the date of consummation of such Asset Sale, the Company shall or shall cause the relevant Restricted Subsidiary to:

(A) apply an amount equal to the Net Cash Proceeds of such Asset Sale to repay Secured Indebtedness and permanently reduce the commitments in respect thereof; or

(B) invest an equal amount, or the amount of Net Cash Proceeds of such Asset Sale not so applied pursuant to clause (A) (or enter into a definitive agreement committing to so invest within such 12-month period, which investment shall be consummated within 6 months after the date of such agreement), in (i) property or assets (other than current assets) of a nature or type or that are used in a Permitted Business or (ii) the Capital Stock of a Person primarily engaged in a Permitted Business that becomes a Restricted Subsidiary as a result of such investment; and

(C) apply such Net Cash Proceeds (to the extent not applied pursuant to clause (A) or (B)) as provided in the following paragraph of this "Limitation on Asset Sales" covenant.

The amount of such Net Cash Proceeds required to be applied (or to be committed to be applied) during such 12-month period as set forth in the preceding sentence and not applied as so required by the end of such period shall constitute "Excess Proceeds."

If, as of the first day of any calendar month, the aggregate amount of Excess Proceeds not theretofore subject to an Offer to Purchase pursuant to this "Limitation on Asset Sales" covenant totals at least $20.0 million, the Company must commence, not later than the fifteenth Business Day of such month, and consummate an Offer to Purchase from the holders on a pro rata basis an aggregate principal amount of Notes and, to the extent permitted or required by the terms thereof, any other of the Company's Senior Indebtedness, equal to the Excess Proceeds on such date, at a purchase price equal to 100% of the principal amount of the Notes and such other Senior Indebtedness, if applicable, on the relevant Payment Date, plus, in each case, accrued interest (if any) to, but excluding, the Payment Date. If any Excess Proceeds remain after consummation of an Offer to Purchase, the Company may use those Excess Proceeds for any purpose not otherwise prohibited by the Indenture. If the aggregate principal amount of Notes and other Senior Indebtedness tendered in response to such Offer to Purchase exceeds the amount of Excess Proceeds, the Trustee will select the Notes and such other Senior Indebtedness to be purchased on a pro rata basis. Upon completion of the Offer to Purchase, the amount of Excess Proceeds will be reset to zero.

Future Subsidiary Guarantors

The Indenture will require that the Company cause each Person that is or becomes a Domestic Restricted Subsidiary following the Closing Date (and is required to be a Subsidiary Guarantor) and any Foreign Restricted Subsidiary that Guarantees any Indebtedness of the Company or any Domestic Restricted Subsidiary of the Company to execute and deliver to the Trustee a supplemental indenture pursuant to which such Domestic Restricted Subsidiary or Foreign Restricted Subsidiary will guarantee the payment and performance of the Notes at the time such Person is or becomes a Domestic

Table of Contents

Restricted Subsidiary that is required to be a Subsidiary Guarantor or Guarantees any such Indebtedness, as applicable.

Repurchase of Notes Upon a Change of Control

The Company must commence, within 30 days of the occurrence of a Change of Control, and consummate an Offer to Purchase for all Notes then outstanding, at a purchase price equal to 101% of the principal amount thereof on the relevant Payment Date, plus accrued interest (if any) to, but excluding, the Payment Date.

The Company cannot assure you that it will have sufficient funds available at the time of any Change of Control to make any payment on outstanding Indebtedness (including repurchases of the Notes) required by the foregoing covenant (or that may be contained in agreements relating to the Company's other Indebtedness which might be outstanding at such time).

The above covenant requiring the Company to repurchase the Notes will, unless consents are obtained, require the Company to repay all Indebtedness then outstanding which by its terms would prohibit such Note repurchase, either prior to or concurrently with such Note repurchase.

SEC Reports and Reports to Holders

Whether or not the Company is then required to file reports with the SEC under the Exchange Act, the Company will file with the SEC (unless the SEC will not accept or does not permit such a filing, in which case the Company will supply to the Trustee in electronic form for forwarding to each holder upon request by such holder, without cost to any holder and at the expense of the Company), within the time periods specified in the SEC's rules and regulations:

(1) all quarterly and annual financial information with respect to the Company and its Subsidiaries that would be required to be contained in a filing with the SEC on Forms 10-Q and 10-K if the Company were required to file such Forms under the Exchange Act, including a "Management's Discussion and Analysis of Financial Condition and Results of Operations," and, with respect to the annual information only, a report on the annual financial statements by the Company's certified independent accountants; and

(2) all current reports that would be required to be filed with the SEC on Form 8-K if the Company were required to file such reports under the Exchange Act.

If the Company has designated any of its Subsidiaries as Unrestricted Subsidiaries, then the quarterly and annual financial information required by the preceding paragraph will include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, or in Management's Discussion and Analysis of Financial Condition and Results of Operations, of the financial condition and results of operations of the Company and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of the Company.

In addition, the Company agrees that, for so long as any Notes remain outstanding, if at any time it is not required to file with the SEC the reports and other information required by the preceding paragraphs, it will furnish to holders of Notes and prospective investors in the Notes, upon request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

For so long as the Company files the foregoing reports and other information with the SEC, the Company will be deemed to have furnished such reports and other information to the Trustee if the Company has filed such reports and other information with the SEC via the EDGAR filing system or any successor electronic filing system and such reports are publicly available.

If an Event of Default (other than an Event of Default specified in clause (7) or (8) above that occurs with respect to the Company) occurs and is continuing under the Indenture, the Trustee or holders of at least 25% in aggregate principal amount of the Notes then outstanding by written notice to the Company (and to the Trustee if such notice is given by the holders), may, and the Trustee at the written request of such holders shall, declare the principal amount of, premium, if any, and accrued

Table of Contents

interest on the Notes to be immediately due and payable. Upon a declaration of acceleration, such principal amount, premium, if any, and accrued interest shall be immediately due and payable.

Notwithstanding the foregoing, to the extent elected by the Company, the sole remedy for an Event of Default relating to the failure to comply with "—Certain Covenants—SEC Reports and Reports to Holders" and for any failure to comply with the requirements of Section 314(a)(1) of the Trust Indenture Act, will for the first 120 days after the occurrence of such an Event of Default consist exclusively of the right to receive additional interest on the Notes at an annual rate equal to 0.50% of the principal amount of the Notes. This additional interest will be paid semi-annually in arrears, with the first semi-annual payment due on the first interest payment date following the date on which the additional interest begins to accrue on any Notes. The additional interest will accrue on all outstanding Notes from and including the date on which such Event of Default first occurs to, but excluding, the 120th day thereafter (or such earlier date on which such Event of Default shall have been cured or waived). On such 120th day (or earlier, if such Event of Default shall have been cured or waived prior to such 120th day), such special interest will cease to accrue and, if such Event of Default has not been cured or waived prior to such 120th day, the Notes will be subject to acceleration as provided above. In the event the Company does not elect to pay additional interest upon an Event of Default in accordance with this paragraph, the Notes will be subject to acceleration as provided above. If the Company elects to pay such additional interest, it will notify the Trustee and paying agent of such election on or before the close of business on the date on which such Event of Default first occurs.

In the event of a declaration of acceleration because an Event of Default set forth in clause (5) above has occurred and is continuing, such declaration of acceleration shall be automatically rescinded and annulled if the event of default triggering such Event of Default pursuant to such clause (5) shall be remedied or cured by the Company or the relevant Restricted Subsidiary or waived by the holders of the relevant Indebtedness within 60 days after the declaration of acceleration with respect thereto.

If an Event of Default specified in clause (7) or (8) above occurs with respect to the Company, the principal amount of, premium, if any, and accrued interest on the Notes then outstanding shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any holder.

The holders of at least a majority in principal amount of the outstanding Notes, by written notice to the Company and to the Trustee, may waive all past Defaults and rescind and annul a declaration of acceleration and its consequences if (1) all existing Events of Default, other than the nonpayment of the principal of, premium, if any, and interest on the Notes that have become due solely by such declaration of acceleration, have been cured or waived and (2) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction. For information as to the waiver of defaults, see "—Modification and Waiver."

The holders of at least a majority in aggregate principal amount of the outstanding Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee pursuant to the Indenture. However, the Trustee may refuse to follow any direction that conflicts with law or the Indenture, that may involve the Trustee in personal liability, or that the Trustee determines in good faith may be unduly prejudicial to the rights of holders of Notes not joining in the giving of such direction, and may take any other action it deems proper that is not inconsistent with any such direction received from holders of such Notes. The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by the Indenture at the request or direction of any of the holders pursuant to the Indenture, unless such holders shall have offered to the Trustee security or indemnity satisfactory to the Trustee against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction.

Table of Contents

A holder may not pursue any remedy with respect to the Indenture or the Notes unless:

(1) the holder gives the Trustee written notice of a continuing Event of Default;

(2) the holders of at least 25% in aggregate principal amount of outstanding Notes make a written request to the Trustee to pursue the remedy;

(3) such holder or holders offer the Trustee indemnity and/or security satisfactory to the Trustee against any costs, liability or expense;

(4) the Trustee does not comply with the request within 60 days after receipt of the request and the offer of indemnity and/or security; and

(5) during such 60-day period, the holders of a majority in aggregate principal amount of the outstanding Notes do not give the Trustee a direction that is inconsistent with the request.

However, such limitations do not apply to the right of any holder of a Note to receive payment of the principal amount of, premium, if any, or interest on, such Note or to bring suit for the enforcement of any such payment, on or after the due date expressed in the Notes, which right shall not be impaired or affected without the consent of the holder.

The Indenture requires certain of the Company's officers to certify, on or before a date not more than 90 days after the end of each fiscal year, that a review has been conducted of the activities of the Company and the Restricted Subsidiaries and their performance under the Indenture and that the Company and the Restricted Subsidiaries have fulfilled all obligations thereunder, or, if there has been a default in the fulfillment of any such obligation, specifying each such default and the nature and status thereof. The Company is also obligated to notify the Trustee of any default or defaults in the performance of any covenants or agreements under the Indenture.

Defeasance

Defeasance and Discharge

The Indenture provides that the Obligors will be deemed to have paid and will be discharged from any and all obligations in respect of the outstanding Notes, and the provisions of the Indenture will no longer be in effect with respect to the Notes (except for, among other matters, certain obligations to register the transfer or exchange of the Notes, to replace stolen, lost or mutilated Notes, to maintain paying agencies and to hold monies for payment in trust) if, among other things:

(1) the Company has deposited with the Trustee, in trust, money and/or U.S. Government Obligations that through the payment of interest and principal in respect thereof in accordance with their terms will provide money in an amount sufficient to pay the principal of, premium, if any, and accrued interest on the Notes on the Stated Maturity of such payments in accordance with the terms of the Indenture and the Notes;

(2) the Company has delivered to the Trustee

(A) either (i) an opinion of counsel to the effect that holders of Notes will not recognize income, gain or loss for federal income tax purposes as a result of the Company's exercise of its option under this "defeasance" provision and will be subject to federal income tax on the same amounts and in the same manner and at the same times as would have been the case if such deposit, defeasance and discharge had not occurred, which opinion of counsel must be based upon a change in applicable U.S. federal income tax law after the Closing Date or (ii) a ruling directed to the Trustee received from the Internal Revenue Service to the same effect as the aforementioned opinion of counsel; and

Table of Contents

(B) an opinion of counsel to the effect that the creation of the defeasance trust does not violate the Investment Company Act of 1940 and that, after the passage of 123 days following the deposit, the trust fund will not be subject to the effect of Section 547 of the United States Bankruptcy Code or Section 15 of the New York Debtor and Creditor Law;

(3) immediately after giving effect to such deposit, on a pro forma basis, no Event of Default, or event that after the giving of notice or lapse of time or both would become an Event of Default, shall have occurred and be continuing on the date of such deposit (other than any Default or Event of Default resulting from the borrowing of funds to be applied to make the deposit referred to in clause (1) above and the granting of Liens in connection therewith), and such deposit shall not result in a breach or violation of, or constitute a default under, any other agreement or instrument to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound; and

(4) if at such time the Notes are listed on a national securities exchange, the Company has delivered to the Trustee an opinion of counsel to the effect that the Notes will not be delisted as a result of such deposit, defeasance and discharge.

Defeasance of Certain Covenants and Certain Events of Default

The Indenture further provides that the provisions of the Indenture will no longer be in effect with respect to clause (3) under "—Consolidation, Merger and Sale of Assets" and all the covenants described herein under "—Certain Covenants," and clause (3) under "—Events of Default" with respect to such clause (3) under "—Consolidation, Merger and Sale of Assets," clause (4) under "—Events of Default" with respect to such other covenants and clauses (5), (6), (9) and (10) under "—Events of Default" shall be deemed not to be Events of Default upon, among other things, the deposit with the Trustee, in trust, of money and/or U.S. Government Obligations that through the payment of interest and principal in respect thereof in accordance with their terms will provide money in an amount sufficient to pay the principal of, premium, if any, and accrued interest on the Notes on the Stated Maturity of such payments in accordance with the terms of the Indenture and the Notes, the satisfaction of the provisions described in clauses (2)(B), (3) and (4) under "—Defeasance—Defeasance and Discharge" and the delivery by the Company to the Trustee of an opinion of counsel to the effect that, among other things, the holders will not recognize income, gain or loss for federal income tax purposes as a result of such deposit and defeasance of certain covenants and Events of Default and will be subject to federal income tax on the same amount and in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred.

Defeasance and Certain Other Events of Default

In the event the Company exercises its option to omit compliance with certain covenants and provisions of the Indenture as described in the immediately preceding paragraph and the Notes are declared due and payable because of the occurrence of an Event of Default that remains applicable, the amount of money and/or U.S. Government Obligations on deposit with the Trustee will be sufficient to pay amounts due on such Notes at the time of their Stated Maturity but may not be sufficient to pay amounts due on such Notes at the time of the acceleration resulting from such Event of Default. However, the Company will remain liable for such payments.

Table of Contents

Satisfaction and Discharge

The Indenture will be discharged and will cease to be of further effect when:

(1) either:

(a) all Notes that have been authenticated and delivered (other than destroyed, lost or stolen Notes that have been replaced, Notes that are paid and Notes for whose payment money or securities have theretofore been deposited in trust and thereafter repaid to the Company) have been delivered to the Trustee for cancellation and the Company or any other Obligor has paid all sums payable under the Indenture; or

(b) all Notes mature within one year or are to be called for redemption within one year and the Company or any other Obligor has irrevocably deposited with the Trustee, as trust funds in trust solely for the benefit of the holders, money or U.S. Government Obligations sufficient, without consideration of any reinvestment of interest, to pay the principal of, premium, if any, and accrued interest on the Notes to the date of maturity or redemption and all other sums payable under the Indenture;

(2) no Default or Event of Default shall have occurred and be continuing on the date of such deposit and such deposit will not result in a breach or violation of, or constitute a default under, the Indenture (other than any Default or Event of Default resulting from the borrowing of funds to be applied to make the deposit referred to in clause (1) above and the granting of Liens in connection therewith) or any other instrument to which the Company or any other Obligor is a party or by which the Company or any other Obligor is bound; and

(3) the Company has delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of the Notes at maturity or the redemption date, as applicable.

In addition, the Company must deliver an Officers' Certificate and an opinion of counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied.

Modification and Waiver

With the Consent of Holders

Modifications and amendments of the Indenture and the Notes may be made by the Company, the Subsidiary Guarantors and the Trustee (upon the Trustee's receipt of an officer's certificate and opinion of counsel confirming compliance of such modification or amendment with the requirements of the Indenture) with the consent of the holders of not less than a majority in aggregate principal amount of the Notes then outstanding, and the holders of not less than a majority in aggregate principal amount of the Notes then outstanding, by written notice to the Trustee, may waive future compliance by the Company and the Subsidiary Guarantors or any other Restricted Subsidiaries with any provision of the Indenture or the Notes;provided,however, that no such modification, amendment or waiver may, without the consent of each affected holder of Notes (with respect to any Notes held by a non-consenting holder):

(1) change the Stated Maturity of the principal of, or any installment of interest on, any Note or alter the provisions with respect to the redemption of the notes described above under "—Optional Redemption");provided,however, that any modification or amendment of the "Limitation on Asset Sales" or the "Repurchase of Notes Upon a Change of Control" covenants occurring prior to any obligation of the Company to purchase Notes arising thereunder shall not be deemed to change the Stated Maturity of the principal of, or any installment of interest on, any Note;

(1) to cure any ambiguity, defect or inconsistency in the Indenture, provided that such action shall not adversely affect the interests of the holders of the Notes;

(2) to provide for the assumption of the Company's or a Subsidiary Guarantor's obligations to holders of Notes and Subsidiary Guarantees if and to the extent required in the case of a merger or consolidation or sale or all or substantially all of the Company's or such Subsidiary Guarantor's assets, as applicable, in accordance with the "Consolidation, Merger and Sale of Assets" covenant;

No Personal Liability of Incorporators, Stockholders, Officers, Directors, or Employees

The Indenture provides that no recourse for the payment of the principal of, premium, if any, or interest on the Notes or for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any obligation, covenant or agreement of the Company or any Subsidiary Guarantor in the Indenture, or in any of the Notes or because of the creation of any Indebtedness represented

Table of Contents

thereby, shall be had against any incorporator or against any past, present or future stockholder, other equity holder, officer, director, employee or controlling Person, as such, of either the Company or the Subsidiary Guarantors or of any of their respective successors. Each holder, by accepting the Notes, waives and releases all such liability.

Trustee

The Indenture provides that, except during the continuance of a Default, the Trustee will perform only such duties as are specifically set forth in the Indenture. If an Event of Default has occurred and is continuing, the Trustee will use the same degree of care and skill in its exercise of the rights and powers vested in it under the Indenture as a prudent person would exercise under the circumstances in the conduct of such person's own affairs.

The Indenture and the provisions of the Trust Indenture Act incorporated by reference into the Indenture contain limitations on the rights of the Trustee, if it should become a creditor of an Obligor, to obtain payment of claims in certain cases or to realize on certain property received by it in respect of any such claims, as security or otherwise. The Trustee is permitted to engage in other transactions with the Company or the Company's affiliates;provided that, if it acquires any conflicting interest, it must eliminate such conflict or resign.

Book-Entry; Delivery and Form

The Notes will initially be represented by one or more global notes in registered form without interest coupons attached.

Global notes will be exchanged with the Trustee as custodian for DTC, in New York, New York, and registered in the name of DTC or its nominee, in each case for credit to an account of a direct or indirect participant in DTC as described below. Except as set forth below, global notes may be transferred only to another nominee of DTC or to a successor of DTC or its nominee, in whole and not in part. Except in the limited circumstances described below under "—Exchange of Global Notes for Certificated Notes," beneficial interests in global notes may not be exchanged for Notes in certificated form and owners of beneficial interests in global notes will not be entitled to receive physical delivery of Notes in certificated form.

Depositary Procedures

The following description of the operations and procedures of DTC, Euroclear System S.A./N.V., or "Euroclear," as operator of the Euroclear System, and Clearstream Banking,société anonyme, or "Clearstream," is provided solely as a matter of convenience. These operations and procedures are solely within the control of the respective settlement systems and are subject to changes by them. We take no responsibility for these operations and procedures and urge investors to contact the system or their participants directly to discuss these matters.

DTC has advised us that it is a limited-purpose trust company created to hold securities for its participating organizations, or "participants," and to facilitate the clearance and settlement of transactions in those securities between the participants through electronic book-entry changes in accounts of the participants. The participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. Access to DTC's system is also available to other entities such as banks, brokers, dealers and trust companies, which are referred to as "indirect participants," that clear though or maintain a direct or indirect custodial relationship with a participant. Persons who are not participants may beneficially own securities held by or on behalf of DTC only through the participants or the indirect participants. The ownership interests in, and transfers of ownership interests in, each security held by or on behalf of DTC are recorded on the records of the participants and indirect participants.

Table of Contents

DTC has also advised us that, pursuant to procedures established by it:

(1): upon deposit of the global notes, DTC will credit the accounts of participants with portions of the principal amount of the global notes; and
(2): ownership of these interests in global notes will be shown on, and the transfer of ownership of these interests will be effected only through, records maintained by DTC (with respect to the participants) or by the participants and the indirect participants (with respect to other owners of beneficial interests in the global notes).

All interests in a global note may be subject to the procedures and requirements of DTC. Interests in a global note held through Euroclear or Clearstream also may be subject to the procedures and requirements of those systems. The laws of some states require that certain persons take physical delivery in definitive form of securities that they own. Consequently, the ability to transfer beneficial interests in a global note to persons that are subject to those requirements will be limited to that extent. Because DTC may act only on behalf of participants, which in turn act on behalf of indirect participants, the ability of a person having beneficial interests in a global note to pledge those interests to persons that do not participate in the DTC system, or otherwise take actions in respect of those interests, may be affected by the lack of a physical certificate evidencing such interests.

Except as described below, owners of interests in the global notes will not have Notes registered in their names, will not receive physical delivery of Notes in registered, certificated form, and will not be considered the registered owners or holders thereof under the Indenture for any purpose.

Payments in respect of the principal of and premium, interest and special interest, if any, on a global note registered in the name of DTC or its nominee will be payable to DTC in its capacity as the registered holder under the Indenture. Under the terms of the Indenture, we and the Trustee will treat the persons in whose names Notes, including global notes, are registered as the owners of such Notes for the purpose of receiving payments and for all other purposes. Consequently, neither we, the Trustee nor any agent of us or the Trustee has or will have any responsibility or liability for:

(1): any aspect or accuracy of DTC's records or any participant's or indirect participant's records relating to, or payments made on account of, beneficial ownership interests in global notes, or for maintaining, supervising or reviewing any of DTC's records or any participant's or indirect participant's records relating to the beneficial ownership interests in global notes; or
(2): any other matter relating to the actions and practices of DTC or any of its participants or indirect participants.

DTC has advised us that its current practice, upon receipt of any payment in respect of securities such as the Notes (including payments of principal and interest), is to credit the accounts of the relevant participants with the payment on the payment date in amounts proportionate to their respective ownership interests in the relevant security as shown on DTC's records. Payments by the participants and the indirect participants to the beneficial owners of Notes will be governed by standing instructions and customary practices and will be the responsibility of the participants or the indirect participants and will not be the responsibility of DTC, the Trustee or us. Neither we nor the Trustee will be liable for any delay by DTC or any of its participants in identifying the beneficial owners of any Notes, and we and the Trustee may conclusively rely on and will be protected in relying on instructions from DTC or its nominee as the registered owner of the Notes for all purposes.

DTC has advised us that it will take any action permitted to be taken by a holder of the Notes only at the direction of one or more participants to whose account DTC has credited the interests in the global notes and only in respect of the portion of the aggregate principal amount of the Notes as to which such participant or participants has or have given such direction. If there has occurred and is continuing an Event of Default under the Notes, DTC reserves the right to exchange the applicable

Table of Contents

global notes for Notes in registered, certificated form, and to distribute such certificated forms of Notes to its participants.

Exchange of Global Notes for Certificated Notes

A global note is exchangeable for definitive notes in registered, certificated form if:

•: DTC (a) notifies us that it is unwilling or unable to continue as depositary for the applicable global notes and we thereupon fail to appoint a successor depositary within 90 days or (b) has ceased to be a clearing agency registered under the Exchange Act;
•: we, at our option, notify the Trustee in writing that we elect to cause the issuance of the Notes in certificated form; or
•: there has occurred and is continuing an Event of Default with respect to the Notes.

In addition, beneficial interests in a global note may be exchanged for certificated Notes upon prior written notice given to the Trustee by DTC on behalf of its direct or indirect participants in accordance with the Indenture.

In all cases, certificated Notes delivered in exchange for any global note or beneficial interests in a global note will be registered in the names, and issued in any approved denominations, requested by DTC on behalf of its direct or indirect participants (in accordance with DTC's customary procedures).

Same Day Settlement and Payment

Except for trades involving only Euroclear and Clearstream participants, interests in the global notes will trade in DTC's same-day funds settlement system and secondary market trading activity in such interests will therefore settle in immediately available funds, subject in all cases to the rules and procedures of DTC and the participants. Transfers between participants in Euroclear and Clearstream will be effected in the ordinary way in accordance with their respective rules and operating procedures.

Cross-market transfers between DTC participants, on the one hand, and Euroclear or Clearstream participants, on the other hand, will be effected through DTC in accordance with DTC's rules on behalf of Euroclear or Clearstream, as the case may be, by its respective depositary. Such cross-market transactions will require delivery of instructions to Euroclear or Clearstream, as the case may be, by the counterparty in such system in accordance with the rules and procedures and within the established deadlines (Brussels time) of such system. Euroclear or Clearstream, as the case may be, will, if the transaction meets its settlement requirements, deliver instructions to its respective depositary to take action to effect final settlement on its behalf by delivering or receiving interests in the relevant global note from DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Euroclear participants and Clearstream participants may not deliver instructions directly to the depositories for Euroclear or Clearstream.

Because of time zone differences, the securities account of a Euroclear or Clearstream participant purchasing an interest in a global note from a DTC participant will be credited, and any such crediting will be reported to the relevant Euroclear or Clearstream participant, during the securities settlement processing day (which must be a business day for Euroclear and Clearstream) immediately following the settlement date of DTC. DTC has advised us that cash received in Euroclear or Clearstream as a result of sales of interests in a global note by or through a Euroclear or Clearstream participant to a DTC participant will be received with value on the settlement date of DTC but will be available in the relevant Euroclear or Clearstream cash account only as of the business day for Euroclear or Clearstream following DTC's settlement date.

Although DTC, Euroclear and Clearstream have agreed to the foregoing procedures in order to facilitate transfers of interests in global notes among participants, they are under no obligation to

100

Table of Contents

perform or to continue to perform those procedures, and may discontinue or change those procedures at any time. Neither we, the Trustee nor any agent of us or the Trustee will have any responsibility for the performance by DTC, Euroclear, Clearstream or their respective participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

ERISA CONSIDERATIONS

The Employee Retirement Income Security Act of 1974, as amended, or "ERISA," imposes certain requirements on "employee benefit plans" (as defined in ERISA) subject to Title I of ERISA, including entities such as collective investment funds and separate accounts whose underlying assets include the assets of such plans, which we refer to collectively as "ERISA Plans," and on those persons who are fiduciaries with respect to ERISA Plans.

Section 406 of ERISA and Section 4975 of the Code prohibit certain transactions involving the assets of an ERISA Plan (Section 4975 of the Code also imposes prohibitions for certain plans that are not subject to Title I of ERISA but which are subject to Section 4975 of the Code, such as individual retirement accounts, which we refer to together with ERISA Plans as the "Plans") and certain persons (referred to as "parties in interest" or "disqualified persons") having certain relationships to such Plans, unless a statutory or administrative exemption is applicable to the transaction. A party in interest or disqualified person who engages in a prohibited transaction may be subject to excise taxes and other penalties and liabilities under ERISA and Section 4975 of the Code. Accordingly, each original or subsequent purchaser or transferee of a note that is or may become a Plan is responsible for determining that its purchase and holding of such note will not constitute a prohibited transaction under ERISA or Section 4975 of the Code.

THE PRECEDING DISCUSSION IS ONLY A SUMMARY OF CERTAIN ERISA IMPLICATIONS OF AN INVESTMENT IN THE NOTES AND DOES NOT PURPORT TO BE COMPLETE. NOTE HOLDERS SHOULD CONSULT WITH THEIR OWN LEGAL, TAX, FINANCIAL AND OTHER ADVISORS TO REVIEW THESE IMPLICATIONS IN LIGHT OF SUCH NOTE HOLDERS' PARTICULAR CIRCUMSTANCES.

CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following is a summary of certain U.S. federal income tax considerations of the ownership and disposition of the notes. This summary is based upon provisions of the Internal Revenue Code of 1986, as amended (the "Code"), applicable regulations, administrative rulings and judicial decisions in effect as of the date of this offering memorandum, any of which may subsequently be changed, possibly retroactively, or interpreted differently by the Internal Revenue Service(the "IRS") so as to result in U.S. federal income tax consequences different from those discussed below. This summary does not address any U.S. federal tax considerations other than U.S. federal income tax considerations (such as estate or gift tax considerations), or considerations under the tax laws of any state, local or foreign jurisdiction.

Except where noted, this summary deals only with a note held as a capital asset (within the meaning of Section 1221 of the Code) by a beneficial owner who purchases the note on original issuance at the first price, which we refer to as the "issue price," at which a substantial portion of the notes are sold for cash to persons other than bond houses, brokers, or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers. This summary does not address all aspects of U.S. federal income taxation and does not deal with all tax consequences that may be relevant to holders in light of their personal circumstances or with special categories of holders, such as:

•: dealers in securities or currencies, financial institutions, regulated investment companies, real estate investment trusts, tax-exempt entities, insurance companies and traders in securities that elect to use a mark-to-market method of accounting for their securities;
•: persons holding notes as a part of a hedging, integrated, conversion or constructive sale transaction or a straddle;
•: U.S. holders, as defined below, whose "functional currency" is not the U.S. dollar;
•: entities treated as partnerships for U.S. federal income tax purposes and investors therein;
•: certain former citizens or residents of the United States;
•: persons subject to alternative minimum tax;

In this discussion, we use the term "U.S. holder" to refer to a beneficial owner of notes that is, for U.S. federal income tax purposes:

•: an individual who is a citizen or resident of the United States;
•: a corporation (or any other entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia;
•: an estate the income of which is subject to U.S. federal income taxation regardless of its source; or
•: a trust, if it (1) is subject to the primary supervision of a court within the United States and one or more U.S. persons have the authority to control all substantial decisions of the trust, or (2) has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

We use the term "non-U.S. holder" to describe a beneficial owner of notes that, for U.S. federal income tax purposes, is an individual, corporation, estate or trust and is not a U.S. holder.

If any entity treated as a partnership for U.S. federal income tax purposes holds notes, the tax treatment of a partner or member generally will depend upon the status of the partner or member and

124

Table of Contents

the activities of the entity. If you are a partner or member in such an entity considering an investment in the notes, you should consult your own tax advisors.

As a holder of the notes, you should consult your own tax advisors concerning the U.S. federal income, estate and gift tax consequences to you in light of your own specific situation, as well as consequences arising under the laws of any other taxing jurisdiction.

Treatment of the Exchange

The exchange of an old note for a new note pursuant to the exchange offer will not constitute a "significant modification" of the old note for U.S. federal income tax purposes and, accordingly, the new note received will be treated as a continuation of the old note in the hands of such holder. As a result, there will be no U.S. federal income tax consequences to a holder who exchanges an old note for a new note pursuant to the exchange offer, any such holder will have the same adjusted tax basis and holding period in the new note as it had in the old note immediately before the exchange and payments on the new notes will be treated in the same manner as such payments were treated with respect to the old notes. A holder who does not exchange its old notes for new notes pursuant to the exchange offer will not recognize any gain or loss, for U.S. federal income tax purposes, upon consummation of the exchange offer.

Effect of Certain Contingencies

In certain circumstances (see, for example "Description of the Notes—Optional Redemption" and "Description of the Notes—Certain Covenants—Repurchase of Notes Upon Change of Control" and "Exchange Offer; Registration Rights."), we may be obligated to pay amounts in excess of stated interest or principal on the new notes. Under the applicable Treasury Regulations, such contingencies should not cause the new notes to be subject to special rules applicable to contingent payment debt instruments if, based on all the facts and circumstances as of the date on which the new notes are issued, there is only a remote likelihood that any such contingencies will occur, or if such contingencies, in the aggregate, are considered incidental. We believe that the foregoing contingencies are remote and/or incidental and, therefore, that such contingencies should not cause the new notes to be treated as contingent payment debt instruments. Our determination is binding on a holder unless such holder discloses its contrary position in the manner required by applicable Treasury Regulations. Our determination, however, is not binding on the IRS, and if the IRS were to challenge this determination, a holder subject to U.S. federal income taxation may be required to accrue additional income on the new notes in excess of cash received, and to treat as ordinary income rather than capital gain any income realized on the taxable disposition of such notes. Holders should consult their own tax advisors regarding the potential application to the notes of the contingent payment debt regulations and the consequences thereof.

The remainder of this discussion assumes that the new notes will not be treated as contingent payment debt instruments.

Consequences to U.S. Holders

Payment of Stated Interest

Subject to the discussion of original issue discount, or OID, below, stated interest on a note generally will be taxable to a U.S. holder as ordinary income at the time it is received or accrued in accordance with the U.S. holder's usual method of accounting for U.S. federal income tax purposes.

125

Table of Contents

Original Issue Discount

Because the stated principal amount of the original notes exceeded the issue price of the original notes by more than ade minimis amount, the original notes were treated as issued with OID for U.S. federal income tax purposes. Accordingly, the new notes will continue to be treated as being issued with OID for U.S. federal income tax purposes.

A U.S. Holder will be required to include the OID on the notes in gross income (as ordinary income) for U.S. federal income tax purposes as it accrues on a constant "yield to maturity" basis, before the receipt of cash payments attributable to the OID and regardless of such U.S. holder's regular method of accounting for U.S. federal income tax purposes.

The amount of OID includible in income by a U.S. Holder generally will be the sum of the "daily portions" of OID with respect to the notes for each day during the taxable year or portion of the taxable year in which a U.S. holder holds the notes ("accrued OID"). The daily portion is determined by allocating to each day in any "accrual period" a pro rata portion of the OID allocable to that accrual period. The "accrual period" of a note may vary in length over the term of the note, provided that each accrual period is no longer than one year and each scheduled payment of principal or interest occurs on either the first or last day of an accrual period. The amount of OID allocable to any accrual period is an amount equal to the excess, if any, of (i) the product of the note's adjusted issue price at the beginning of such accrual period and its yield to maturity (determined on the basis of compounding at the close of each accrual period and properly adjusted for the length of the accrual period) over (ii) the amount of any stated interest on the note allocable to the accrual period. The adjusted issue price of the notes at the beginning of any accrual period generally is equal to their issue price increased by the accrued OID for each prior accrual period previously includible in gross income).

When required and if applicable, we will furnish annually to the IRS and to U.S. holders of the notes information with respect to the OID accruing while the notes are held. The issue price, amount of OID and the yield to maturity of the notes may be obtained by writing to EarthLink, Inc., 1375 Peachtree Street, Atlanta, Georgia 30309, Attention: Louis Alterman, Vice President, Investor Relations, Telephone: (404)748-7650, Facsimile: (678)472-3252; E-mail: altermanlo@corp.earthlink.net.

Sale, Redemption or Other Taxable Disposition of Notes

A U.S. holder generally will recognize gain or loss upon the sale, redemption or other taxable disposition of a new note equal to the difference between the amount realized (less any portion attributable to accrued but unpaid stated interest, which amount will be taxable as ordinary income, to the extent not previously so taxed) upon the sale, redemption or other taxable disposition and the U.S. holder's adjusted tax basis in the new note. A U.S. holder's adjusted tax basis in a new note generally will be equal to the amount that such U.S. holder paid for the original note, increased by the amount of OID previously included in income by the U.S. holder with respect to the notes. Any gain or loss recognized on a sale, redemption or other taxable disposition of the note generally will be capital gain or loss. If, at the time of the sale, redemption or other taxable disposition of the note, a U.S. holder is treated as holding the note for more than one year, this capital gain or loss will be long-term capital gain or loss. Otherwise, this capital gain or loss will be short-term capital gain or loss. In the case of certain non-corporate U.S. holders (including individuals), long-term capital gain generally will be subject to a maximum U.S. federal income tax rate of 15%, which maximum tax rate currently is scheduled to increase to 20% for dispositions occurring during the taxable years beginning on or after January 1, 2013. A U.S. holder's ability to deduct capital losses may be limited.

Information Reporting and Backup Withholding

Information reporting requirements generally will apply to payments of interest and accruals of OID on the notes and the proceeds of a sale, redemption or other taxable disposition of a note paid to

126

Table of Contents

a U.S. holder unless the U.S. holder is an exempt recipient. Backup withholding (currently at the rate of 28%, and currently scheduled to increase to 31% for payments made after December 31, 2012) will apply to those payments if the U.S. holder fails to provide its correct taxpayer identification number, or certification of exempt status, if the U.S. holder is notified by the IRS that it has become subject to backup withholding due to a prior failure to report in full payments of interest and dividend income, or otherwise fails to comply with applicable requirements of the backup withholding rules.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against a U.S. holder's U.S. federal income tax liability if the required information is furnished in a timely manner to the IRS.

Medicare Tax on Unearned Income

Recently enacted legislation requires certain U.S. holders that are individuals, estates or trusts to pay an additional 3.8% tax on, among other things, interest (including OID) on and gains from the sale or other disposition of notes for taxable years beginning after December 31, 2012. U.S. holders that are individuals, estates or trusts should consult their tax advisors regarding the effect, if any, of this legislation on their ownership and disposition of the notes.

Consequences to Non-U.S. Holders

Payment of Interest

Subject to the discussion below concerning backup withholding, U.S. federal withholding tax will not apply to any payment of interest (which, for purposes of this discussion of non-U.S. holders, includes OID) on a note to a non-U.S. holder provided that:

•: interest paid on the note is not effectively connected with the non-U.S. holder's conduct of a trade or business within the United States;
•: the non-U.S. holder does not actually or constructively own 10% or more of the total combined voting power of all classes of our stock that are entitled to vote within the meaning of section 871(h)(3) of the Code;
•: the non-U.S. holder is not a bank whose receipt of interest on a note is described in section 881(c)(3)(A) of the Code;
•: the non-U.S. holder is not a controlled foreign corporation that is related to us (actually or constructively) through stock ownership; and
•: (1) the non-U.S. holder provides its name and address, and certifies, under penalties of perjury, that it is not a U.S. person (which certification may be made on an IRS Form W-8BEN or other applicable form) or (2) the non-U.S. holder holds the notes through certain foreign intermediaries or certain foreign partnerships, and the non-U.S. holder and the foreign intermediary or foreign partnership satisfies the certification requirements of applicable U.S. Treasury regulations.

If a non-U.S. holder cannot satisfy the requirements described above, payments of interest will be subject to the 30% U.S. federal withholding tax, unless the non-U.S. holder provides us with a properly executed (1) IRS Form W-8BEN (or other applicable form) claiming an exemption from or reduction in withholding under the benefit of an applicable income tax treaty or (2) IRS Form W-8ECI (or other applicable form) stating that interest paid on the notes is not subject to withholding tax because it is effectively connected with the non-U.S. holder's conduct of a trade or business within the United States. Effectively connected interest will be subject to U.S. federal income taxon a net income basis in generally the same manner as a U.S. holder is taxed (unless any applicable income tax treaty provides otherwise). If a non-U.S. holder is a foreign corporation, it also may be subject to a branch profits tax

127

Table of Contents

equal to 30% (or lesser rate under an applicable income tax treaty) of its earnings and profits for the taxable year, subject to adjustments, that are effectively connected with its conduct of a trade or business within the United States.

Sale, Redemption or Other Taxable Disposition of Notes

Any gain realized by a non-U.S. holder on the sale, redemption or other taxable disposition of a note generally will not be subject to U.S. federal income tax unless:

(1) that gain is effectively connected with a non-U.S. holder's conduct of a trade or business within the United States; or

(2) the non-U.S. holder is an individual who was present in the United States for 183 days or more in the taxable year of that disposition and certain other conditions are met.

If a non-U.S. holder is described in clause (1) above, it will be subject to tax on the net gain derived from the sale, redemption or other taxable disposition in the same manner as if the non-U.S. holder were a U.S. holder. If a non-U.S. holder is a foreign corporation that falls under clause (1) above, it also may be subject to the branch profits tax equal to 30% (or lesser rate as may be specified under an applicable income tax treaty) of its effectively connected earnings and profits. If a non-U.S. holder is an individual described in clause (2) above, such holder will be subject to a flat 30% tax on the gain derived from the sale, redemption or other taxable disposition, which may be offset by certain U.S. source capital losses.

Information Reporting and Backup Withholding

Generally, we must report annually to the IRS and to non-U.S. holders the amount of interestpaid to non-U.S. holders and the amount of tax, if any, withheld with respect to those payments. Copies of the information returns reporting such interest and withholding also may be made available to the tax authorities in the country in which a non-U.S. holder resides under the provisions of an applicable income tax treaty.

In general, a non-U.S. holder will not be subject to backup withholding with respect to payments of interestthat we make, provided the statement described above in the last bullet point under "—Consequences to Non-U.S. Holders—Payment of Interest" has been received and we do not have actual knowledge or reason to know that the holder is a U.S. person, as defined under the Code who is not an exempt recipient.

A non-U.S. holder will be subject to information reporting and, depending on the circumstances, backup withholding with respect to payments of the proceeds of the sale, redemption or other taxable disposition of a note within the United States or conducted through certain U.S.-related financial intermediaries, unless the statement described above has been received, and we do not have actual knowledge or reason to know that a holder is a U.S. person, as defined under the Code, who is not an exempt recipient, or the non-U.S. holder otherwise establishes an exemption.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against a non-U.S. holder's U.S. federal income tax liability if the required information is furnished in a timely manner to the IRS.

This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of new notes received in exchange for original notes where such original notes were acquired as a result of market-making activities or other trading activities. We have agreed in the registration rights agreement that, for a period beginning on the date the exchange offer is consummated and ending on the earlier of 180 days after the effective date of the registration statement of which this prospectus forms a part (which is the date of this prospectus) and the date on which a broker-dealer is no longer required to deliver a prospectus in connection with market-making activities or other trading activities, we will make this prospectus, as amended or supplemented, available to any broker-dealer for use in connection with any such resale.

•: We will not receive any proceeds from any sale of new notes by broker-dealers.
•: New notes received by broker-dealers for their own account pursuant to the exchange offer may be sold from time to time in one or more transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the new notes or a combination of such methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market prices, or at negotiated prices.
•: Any resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any such broker-dealer or the purchasers of any of the new notes.
•: Any broker-dealer that resells new notes that were received by it for its own account pursuant to the exchange offer and any broker or dealer that participates in a distribution of the new notes may be deemed to be an "underwriter" within the meaning of the Securities Act, and any profit on any such resale of new notes and any commissions or concessions received by any such persons may be deemed to be underwriting compensation under the Securities Act.
•: The letter of transmittal states that, by acknowledging that it will deliver a prospectus and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act.

A broker-dealer that acquired original notes directly from us cannot exchange the original notes in the exchange offer. Any holder who tenders in the exchange offer for the purpose of participating in a distribution of the new notes cannot rely on the no-action letters of the staff of the SEC and must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale transaction.

For the period described above, we will promptly send additional copies of this prospectus and any amendment or supplement to this prospectus to any broker-dealer that requests these documents.

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers.

Indemnification of the Officers and Directors of EarthLink, Inc.

EarthLink, Inc. is a corporation organized under the laws of the State of Delaware.

Under Section 145 of the DGCL, a corporation may indemnify its directors, officers, employees and agents and its former directors, officers, employees and agents and those who serve, at the corporation's request, in such capacities with another enterprise, against expenses (including attorneys' fees), as well as judgments, fines and settlements in nonderivative lawsuits, actually and reasonably incurred in connection with the defense of any action, suit or proceeding in which they or any of them were or are made parties or are threatened to be made parties by reason of their serving or having served in such capacity. The DGCL provides, however, that such person must have acted in good faith and in a manner such person reasonably believed to be in (or not opposed to) the best interests of the corporation and, in the case of a criminal action, such person must have had no reasonable cause to believe his or her conduct was unlawful. In addition, the DGCL does not permit indemnification in any action or suit by or in the right of the corporation, where such person has been adjudged liable to the corporation, unless, and only to the extent that, a court determines that such person fairly and reasonably is entitled to indemnity for costs the court deems proper in light of liability adjudication. Indemnity is mandatory to the extent a claim, issue or matter has been successfully defended.

The second restated certificate of incorporation of EarthLink, as amended, contains provisions that provide that no director of EarthLink shall be personally liable to EarthLink or its stockholders for monetary damages for breach of fiduciary duty as a director except for (a) any breach of the director's duty of loyalty to EarthLink or its stockholders; (b) acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of the law; (c) liability under Section 174 of the DGCL; or (d) any transaction from which the director derived an improper personal benefit. EarthLink's second restated certificate of incorporation contains provisions that further provide for the indemnification of directors and officers to the fullest extent applicable law permits. Under the amended and restated bylaws of EarthLink, EarthLink is required to advance expenses an officer or director incurs in defending any such action if the director or officer undertakes to repay such amount if it is determined that the director or officer is not entitled to indemnification.

The third amended and restated bylaws of EarthLink state that EarthLink shall, to the fullest extent permitted or required by the DGCL or other applicable law, as the same exists or may be amended, indemnify and hold harmless any person who is or was a director or officer of EarthLink and who is or was involved in any manner (including, without limitation, as a party or a witness) or is threatened to be made so involved in any threatened, pending or completed investigation, claim, action, suit or proceeding, whether civil, criminal, administrative or investigative (including, without limitation, any action, suit or proceedings by or in the right of EarthLink to procure a judgment in its favor) (a "Proceeding") by reason of the fact that such person is or was a director or officer of EarthLink, or, while a director or officer of EarthLink, is or was serving at the request of EarthLink as a director, officer, employee or agent of another corporation, partnership, limited liability company, joint venture, trust or other entity or enterprise (including, without limitation, any employee benefit plan) (a "Covered Entity") against all liability and loss suffered and expenses (including attorneys' fees), actually and reasonably incurred by such person in connection with such Proceeding; provided, however, that the foregoing shall not apply (i) to a director or officer of EarthLink with respect to a Proceeding that was commenced by such director or officer unless the proceeding was commenced after either (x) the Indemnitee has obtained the approval thereof by the Board, or (y) a Change in Control (as hereinafter defined in Section 12.5(e) has occurred), or (ii) under circumstances in which such indemnification is

prohibited by the DGCL or other applicable law. Any right of an Indemnitee to indemnification under the bylaws shall be a contract right.

EarthLink has in effect directors' and officers' liability insurance that may cover liabilities under the Securities Act.

A corporation may indemnify any person made, or threatened to be made a party to an action by or in the right of the corporation to procure a judgment in its favor if such director or officer acted, in good faith, for a purpose which he reasonably believed to be in, or, in the case of service for any other corporation or any partnership, joint venture, trust, employee benefit plan or other enterprise, not opposed to, the best interests of the corporation, except that no indemnification shall be made in respect of (1) a threatened action, or a pending action which is settled or otherwise disposed of, or (2) any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation, unless and only to the extent that the court in which the action was brought, or, if no action was brought, any court of competent jurisdiction, determines upon application that, in view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnity for such portion of the settlement amount and expenses as the court deems proper.

The certificate of incorporation of LogicalSolutions.net, Inc. states that no director of the corporation shall be personally liable to the corporation or its shareholders for damages for breach of his or her duties in such capacity unless a judgment or other final adjudication adverse to that director establishes that his or her act or omission was committed prior to the filing of the certificate of incorporation or committed in bad faith or involved intentional misconduct or a knowing violation of law, or that he or she personally gained in fact a financial profit or other advantage to which he or she is not legally entitled, or that his or her acts violated Section 719 of the NYBCL.

The certificate of incorporation of LogicalSolutions.net, Inc. further states that the corporation shall, to the fullest extent permitted by Article 7 of the NYBCL as the same may be amended or supplemented, indemnify any and all persons whom it shall have power to indemnify under said Article from and against any and all of his expenses, liabilities or other matters referred to in or covered by said Article, and the indemnification provided herein shall not be deemed exclusive of any other rights to which any person may be entitled under any bylaw, resolution of shareholders, resolution of directors, agreement or otherwise, as permitted by said Article.

The bylaws of LogicalSolutions.net, Inc. state that each person who was or is made a party or is threatened to be made a party to or is otherwise involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (hereinafter a "Proceeding"), by reason of the fact that he or his testator or intestate (a) is or was a director or officer of the corporation or (b) is or was a director or officer of the corporation who serves or served, in any capacity, any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise at the request of the corporation (hereinafter an "Indemnitee"), shall be indemnified and held harmless by the corporation

against all expense, liability and loss [including ERISA excise taxes or penalties, judgments, fines, penalties, amounts paid in settlement (provided the corporation shall have given its prior consent to such settlement, which consent shall not be unreasonably withheld by it) and reasonable expenses, including attorneys' fees] suffered or incurred by such Indemnitee in connection therewith and such indemnification shall continue as to an Indemnitee who has ceased to be a director or officer and shall inure to the benefit of the Indemnitee's heirs and fiduciaries; provided, however, that no indemnification may be made to or on behalf of any director or officer if his acts were committed in bad faith or were the result of active and deliberate dishonesty and were material to the cause of action so adjudicated or otherwise disposed of, or he personally gained in fact a financial profit or other advantage to which he was not legally entitled. Notwithstanding the foregoing, the corporation shall indemnify any such Indemnitee in connection with a Proceeding (or part thereof) initiated by such Indemnitee only if such Proceeding (or part thereof) was authorized by the board of directors of the corporation.

The bylaws of LogicalSolutions.net, Inc. further state that all expenses reasonably incurred by an Indemnitee in connection with a threatened or actual Proceeding with respect to which any such Indemnitee is or may be entitled to indemnification under the bylaws shall be advanced to him or promptly reimbursed by the corporation in advance of the final disposition of such Proceeding, upon receipt of an undertaking by him or on his behalf to repay the amount of such advances, if any, as to which he is ultimately found not to be entitled to indemnification or, where indemnification is granted, to the extent such advances exceed the indemnification to which he is entitled. Such person shall cooperate in good faith with any request by the corporation that common counsel be used by the parties to an action or Proceeding who are similarly situated unless to do so would be inappropriate due to an actual or potential conflict of interest.

The bylaws of LogicalSolutions.net, Inc. state that the corporation may maintain insurance, at its expense, to protect itself and any director or officer of the corporation or another corporation, partnership, joint venture, trust or other enterprise against any expense, liability or loss, whether or not the corporation would have the power to indemnify such person against such expense, liability or loss under the bylaws or applicable law.

Indemnification of the Officers and Directors of Intelecom Data Systems, Inc.

Intelecom Data Systems, Inc. is a corporation organized under the laws of the State of Rhode Island. The Rhode Island Business Corporation Act (the "RIBCA") generally permits a corporation to indemnify a director or officer for expenses incurred by them by reason of their position with the corporation if the person has acted in good faith and with the reasonable belief (i) in the case of conduct in his or her official capacity that his or her conduct was in the best interests of the corporation and, (ii) in all other cases, that his or her conduct was at least not opposed to the best interests of the corporation, and with respect to any criminal action or proceeding, he or she had no reasonable cause to believe his or her conduct was unlawful. Unless limited by the corporation's charter, the RIBCA also permits indemnification if a court of appropriate jurisdiction, upon application of a director or officer and such notice as the court shall require, determines that the individual is fairly and reasonably entitled to indemnification in view of all the relevant circumstances, whether or not he or she has met the standard of conduct referred to above. However, the RIBCA does not permit a corporation to indemnify persons (1) in actions brought by or in the right of the corporation if the person is adjudged to be liable to the corporation or (2) in actions in which the director is adjudged to be liable on the basis that personal benefit was improperly received by him or her, although, in both cases, it does permit indemnification, but only of expenses, if, and only to the extent, approved by a court of appropriate jurisdiction. The RIBCA permits the right to indemnification to include the right to be paid by the corporation for expenses the indemnified person incurs in defending the proceeding in advance of its final disposition; provided, that the indemnified party delivers to the corporation a written affirmation of a good faith belief that he or she has met the applicable standards of conduct and that he or she undertakes to repay all amounts advanced if it is ultimately determined that he or she is not entitled to be indemnified under the charter or otherwise. However, under the RIBCA, except where indemnification is ordered by a court of appropriate jurisdiction upon application of any director, officer, employee or agent, no indemnification will be made unless authorized in the specific case after a determination has been made, by the board of directors, special legal counsel or the shareholders that indemnification is permissible in the circumstances because the director, officer, employee or agent has met the standard of conduct for indemnification described above.

The articles of incorporation of Intelecom Data Systems, Inc. provide that no director of the corporation shall be personally liable to the corporation or its stockholders for monetary damages for breach of the director's duty as a director; provided that the foregoing shall not eliminate or limit the

II-16

liability of a director (i) for any breach of the director's duty of loyalty to the corporation or its stockholders; (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; (iii) imposed pursuant to the provisions of Rhode Island General Laws Section 7-1.1-43 or (iv) for any transaction from which the director derived an improper personal benefit (unless said transaction is permitted by Rhode Island General Laws Section 7-1.1-37.1).

The bylaws of Intelecom Data Systems, Inc. provide that each person who at any time is, or shall have been, a director or officer of the corporation, and is threatened to be or is made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he or she is, or was, a director or officer of the corporation, or is or has served at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, shall be indemnified against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred in connection with any such action, suit or proceeding to the fullest extent permitted under Section 7-1.1-4.1 of the RIBCA, as from time to time amended. The foregoing right of indemnification shall in no way be exclusive of any other rights of indemnification to which such director or officer may be entitled, under any bylaw, agreement, vote of shareholders or disinterested directors or otherwise, and shall continue as to a person who has ceased to be a director or officer and shall inure to the benefit of the heirs, executors and administrators of such a person.

Under Section 7-16-8 of the RILLCA, the articles of organization or operating agreement of a limited liability company may eliminate or limit the personal liability of a manager to the limited liability company or to its members for monetary damages for breach of any duty provided for in Section 7-16-17. However, no provision may limit or eliminate the liability of a manager for (1) breach of the manager's duty of loyalty to the limited liability company or its members; (2) acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; (3) the liability imposed pursuant to the provisions of Section 7-16-32 or (4) any transaction from which the manager derived an improper personal benefit, unless the transaction was with the informed consent of the members or a majority of the disinterested managers.

Item 22. Undertakings.

(a) The undersigned registrant hereby undertakes:

1. To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and

(iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

Provided, however, that paragraphs (i), (ii) and (iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

2. That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

3. To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

4. That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(i) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time

shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

5. That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser: (i) any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424; (ii) any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant; (iii) the portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and (iv) any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initialbona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is therefore unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933, and will be governed by the final adjudication of such issue.

(d) The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Item 4, 10(b), 11, or 13 of this form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

(e) The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.
