	Summary of Significant Accounting Policies
	Basis of Presentation
	The accompanying unaudited interim consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. They do not include all of the information and footnotes required by U.S. generally accepted accounting principles (U.S. GAAP) for complete financial statements. Such interim financial information is unaudited but reflects all adjustments that, in the opinion of management, are necessary for the fair presentation of the interim periods presented. All such adjustments are, in the opinion of management, of a normal recurring nature. The results of operations presented in this quarterly report on Form 10-Q are not necessarily indicative of the results that may be expected for the year ending December 31, 2014 or for any future periods. This quarterly report on Form 10-Q should be read in conjunction with the Company’s audited financial statements and footnotes included in its annual report on Form 10-K for the fiscal year ended December 31, 2013.
	The consolidated financial statements include accounts of the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated. In addition, certain other reclassifications have been made to prior year amounts to conform to the current year presentation.
	During the three months ended September 30, 2014, the Company recorded an immaterial error correction of approximately $1,100 relating to previous over billings by a co-location provider.  This correction was recorded as a reduction of costs of revenues.
	Revision of Previously Issued Financial Statements
	As previously disclosed in our 2013 Form 10-K, the consolidated statement of operations was revised to reclassify certain amounts to cost of revenues that were previously reported in general and administrative expenses for the three and nine months ended September 30, 2013.
	The following table summarizes the reclassifications by line item within the unaudited consolidated statement of operations for the three months ended September 30, 2013:
		For the Three Months Ended September 30, 2013
		As					As
		Reported		Reclassifications			Revised
	Cost of services	$	21,773	$	365		$	22,138
	Total cost of revenue	27,051		365			27,416
	Gross profit	15,605		(365		)	15,240
	General and administrative	8,609		(365		)	8,244
	Total operating expenses	25,828		(365		)	25,463
	The following table summarizes the reclassifications by line item within the unaudited consolidated statement of operations for the nine months ended September 30, 2013:
		For the Nine Months Ended September 30, 2013
		As					As
		Reported		Reclassifications			Revised
	Cost of services	$	65,696	$	1,025		$	66,721
	Total cost of revenue	83,774		1,025			84,799
	Gross profit	47,458		(1,025		)	46,433
	General and administrative	25,047		(1,025		)	24,022
	Total operating expenses	77,731		(1,025		)	76,706
	Use of Estimates
	The preparation of the consolidated financial statements and related disclosures in conformity with U.S. GAAP requires management to make judgments, assumptions, and estimates that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results and outcomes may differ from those estimates. The results of operations presented in this quarterly report on Form 10-Q are not necessarily indicative of the results that may be expected for the year ending December 31, 2014 or for any other future periods.
	Recent Accounting Standards
	Recently Issued Accounting Pronouncements
	In April 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-08, which includes amendments that change the requirements for reporting discontinued operations and require additional disclosures about discontinued operations. Under the new guidance, only disposals representing a strategic shift in operations - that is, a major effect on the organization's operations and financial results - should be presented as discontinued operations. Examples include a disposal of a major geographic area, a major line of business, or a major equity method investment. Additionally, this ASU requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income, and expenses of discontinued operations. This update is effective for the Company in the first quarter of 2015. The new guidance would only impact the Company upon the disposal of a business.
	In May 2014, the FASB issued ASU 2014-09, which provides guidance for revenue recognition. The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In doing so, companies will need to use more judgment and make more estimates than under today’s guidance. These may include identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. This guidance will be effective for the Company in the first quarter of 2017. Early adoption is not permitted. The Company is currently in the process of evaluating the impact of adoption of this ASU on its consolidated financial statements.
	In August 2014, the FASB issued ASU 2014-15, which provides guidance for disclosure of uncertainties about an entity’s ability to continue as a going concern. ASU 2014-15 defines management's responsibility to assess an entity's ability to continue as a going concern, and to provide related footnote disclosures in certain circumstances. This guidance will be effective for the Company in the first annual period ending after December 15, 2016; however, early adoption is permitted. The Company does not expect the adoption of this guidance to have a material impact on its consolidated financial statements.

	At September 30, 2014, the Company evaluated its marketable securities and determined unrealized losses were due primarily to fluctuations in interest rates. Management does not believe any of the unrealized losses represented an other-than-temporary impairment based on its evaluation of available evidence as of September 30, 2014. The Company’s intent is to hold these investments to such time as these assets are no longer impaired. The Company views its available-for-sale securities as available for current operations.

	On December 23, 2013, the Company sold 100% of the outstanding common stock of its Web Content Management (WCM) business for $12,341 in cash, net of preliminary working capital adjustments. After allocating goodwill of $3,799 to WCM, the sale resulted in a gain of $3,836, which was included in Other, net in the consolidated statement of operations for the year ended December 31, 2013. During the three months ended March 31, 2014, the Company recorded a working capital adjustment of $(62) (expense), related to new information subsequent to the closing of the acquisition, which is included in Other, net in the consolidated statement of operations for the nine months ended September 30, 2014. This sale was not treated as a discontinued operation because the operations and cash flows of the WCM business cannot be clearly distinguished, operationally or for financial reporting purposes, from the rest of the Company.

	The $10,854 receivable from DG was determined by the Company based on estimated future cash payments equal to the excess of certain current assets over certain current liabilities as of August 30, 2011. During 2013, the Company wrote-off the remaining receivable balance of $412 from DG as it believed the balance was no longer collectible.
	During the three months ended June 30, 2014, the Company received $414 from DG as final settlement for the previously written-off receivable. The Company recorded $269, ($414 cash received, net of tax of $145), as income from discontinued operations during the second quarter of 2014.
	During the three months ended September 30, 2014, the Company incurred $4 (net of tax) in expense related to discontinued operations which is recorded in the accompanying consolidated statements of operations for the three and nine months ended September 30, 2014.

Goodwill and Intangible Assets Disclosure [Abstract]	'
Goodwill and Other Intangible Assets	'
	Goodwill and Other Intangible Assets
	The Company has recorded goodwill and other intangible assets as a result of its business acquisitions. Goodwill is recorded when the purchase price paid for an acquisition exceeds the estimated fair value of the net identified tangible and intangible assets acquired. In each of the Company’s acquisitions, the objective of the acquisition was to expand the Company’s product offerings and customer base and to achieve synergies related to cross selling opportunities, all of which contributed to the recognition of goodwill.
	The Company tests goodwill for impairment on an annual basis or more frequently if events or changes in circumstances indicate that goodwill might be impaired. The Company concluded that it has one reporting unit and assigned the entire balance of goodwill to that reporting unit. The fair value of the reporting unit is determined using the Company’s market capitalization as of its annual impairment assessment date or each reporting date if circumstances indicate the goodwill might be impaired. Items that could reasonably be expected to negatively affect key assumptions used in estimating fair value include but are not limited to:
	•	sustained decline in the Company’s stock price due to a decline in its financial performance due to the loss of key customers, loss of key personnel, emergence of new technologies or new competitors;
	•	decline in overall market or economic conditions leading to a decline in its stock price; and
	•	decline in observed control premiums paid in business combinations involving comparable companies.
	The estimated fair value of the reporting unit is determined using a market capitalization approach. The Company’s market capitalization is adjusted for a control premium based on the estimated average and median control premiums of transactions involving companies comparable to the Company. As of the annual impairment testing date of October 31, 2013 and as of December 31, 2013, the Company determined that goodwill was not impaired. As of September 30, 2014, the Company determined that the estimated fair value of its reporting unit exceeded carrying value by approximately $103,500 or 47%, using the market capitalization of the Company plus an estimated control premium of 40%. Based on this analysis, management believes goodwill is not impaired as of September 30, 2014; however, adverse changes to certain key assumptions as described above could result in a future charge to earnings.
	Foreign currency translation adjustments decreased the carrying amount of goodwill for the three and nine months ended September 30, 2014 by $581 and $452, respectively.
	Other intangible assets that are subject to amortization consisted of the following:

	Akamai Litigation
	In June 2006, Akamai Technologies, Inc., or Akamai, and the Massachusetts Institute of Technology, or MIT, filed a lawsuit against the Company in the United States District Court for the District of Massachusetts alleging that the Company was infringing two patents assigned to MIT and exclusively licensed by MIT to Akamai, United States Patent No. 6,553,413 (the ’413 patent) and United States Patent No. 6,108,703 (the ’703 patent). In September 2006, Akamai and MIT expanded their claims to assert infringement of a third patent United States Patent No. 7,103,645 (the ’645 patent). Before trial, Akamai waived by stipulation its claims of indirect or induced infringement and proceeded to trial only on the theory of direct infringement. In February 2008, a jury returned a verdict in this lawsuit, finding that the Company infringed four claims of the ’703 patent at issue and rejecting the Company’s invalidity defenses. The jury awarded an aggregate of approximately $45,500 which includes lost profits, reasonable royalties and price erosion damages for the period April 2005 through December 31, 2007. In addition, the jury awarded prejudgment interest which the Company estimated to be $2,600 at December 31, 2007. The Company recorded an aggregate $48,100 as a provision for litigation as of December 31, 2007. During 2008, the Company recorded a potential additional provision of approximately $17,500 for potential additional infringement damages and interest. The total provision for litigation at December 31, 2008 was $65,600.
	On July 1, 2008, the court denied the Company’s Motions for Judgment as a Matter of Law (JMOL), Obviousness, and a New Trial. The court also denied Akamai’s Motion for Permanent Injunction as premature and its Motions for Summary Judgment regarding the Company’s equitable defenses. The court conducted a bench trial in November 2008 regarding the Company’s equitable defenses. The Company also filed a motion for reconsideration of the court’s earlier denial of the Company’s motion for JMOL. The Company’s motion for JMOL was based largely upon a clarification in the standard for a finding of joint infringement articulated by the Federal Circuit in the case of Muniauction, Inc. v. Thomson Corp., released after the court denied the Company’s initial motion for JMOL. On April 24, 2009, the court issued its order and memorandum setting aside the adverse jury verdict and ruling that the Company did not infringe Akamai’s ’703 patent and that the Company was entitled to JMOL. Based upon the court’s April 24, 2009 order, the Company reversed the $65,600 provision for litigation previously recorded for this lawsuit as the Company no longer believed that payment of any amounts represented by the litigation provision was probable. The court entered final judgment in favor of the Company on May 22, 2009, and Akamai filed its notice of appeal of the court’s decision on May 26, 2009. On December 20, 2010, the Court of Appeals for the Federal Circuit issued its opinion affirming the trial court’s entry of judgment in the Company’s favor. On February 18, 2011, Akamai filed a motion with the Court of Appeals for the Federal Circuit seeking a rehearing and rehearing en banc. On April 21, 2011, the Court of Appeals for the Federal Circuit issued an order denying the petition for rehearing, granting the petition for rehearing en banc, vacating the December 20, 2010 opinion affirming the trial court’s entry of judgment in the Company’s favor, and reinstated the appeal.
	On August 31, 2012, the Court of Appeals for the Federal Circuit issued its opinion in the case. The Court of Appeals stated that the trial court correctly determined that the Company did not directly infringe Akamai’s ’703 patent and upheld the trial court’s decision to vacate the original jury’s damages award. The Court of Appeals also held that the Company did not infringe Akamai’s ’413 or ’645 patents. A slim majority in this three-way divided opinion also announced a revised legal theory of induced infringement, remanded the case to the trial court, and gave Akamai an opportunity for a new trial to attempt to prove that the Company induced its customers to infringe Akamai’s patent under the Court of Appeals’ new legal standard. On December 28, 2012, the Company filed a petition for writ of certiorari to the United States Supreme Court to appeal this sharply divided Court of Appeals decision. Akamai then filed a cross petition for consideration of the Court of Appeals standard for direct infringement followed by an opposition to the Company’s petition. On January 10, 2014, the Supreme Court granted our petition for writ of certiorari and did not act on Akamai's cross petition. On April 30, 2014, the Supreme Court heard oral argument in our case. On June 2, 2014, the Supreme Court issued its decision and reversed the Federal Circuit's decision, remanding the case back to that court. On July 24, 2014, the Federal Circuit issued an order vacating its prior judgment, reinstating the appeals, dissolving its en banc status, and referring the case back to the original Court of Appeals panel for further proceedings. The Federal Circuit heard arguments on September 11, 2014. The Company does not believe an ultimate loss is probable; therefore, no provision for this lawsuit is recorded in the consolidated financial statements.
	In light of the status of the litigation, the Company believes that there is a reasonable possibility that it has incurred a loss related to the Akamai litigation. While the Company believes that there is a reasonable possibility that a loss has been incurred, the Company is not able to estimate a range of the loss due to the complexity and procedural status of the case. The Company will continue to vigorously defend against the allegation.
	Legal and other expenses associated with this case have been significant. The Company includes these litigation expenses in general and administrative expenses as incurred, as reported in the consolidated statement of operations.
	Other Litigation
	The Company is subject to various other legal proceedings and claims, either asserted or unasserted, arising in the ordinary course of business. While the outcome of these claims cannot be predicted with certainty, management does not believe the outcome of any of these matters will have a material adverse effect on the Company’s business, financial position, results of operations, or cash flows. Litigation relating to the content delivery services industry is not uncommon, and the Company is, and from time to time has been, subject to such litigation. No assurances can be given with respect to the extent or outcome of any such litigation in the future.
	Other Matters
	The Company is subject to indirect taxation in various states and foreign jurisdictions. Laws and regulations that apply to communications and commerce conducted over the Internet are becoming more prevalent, both in the United States and internationally, and may impose additional burdens on the Company conducting business online or providing Internet-related services. Increased regulation could negatively affect the Company’s business directly, as well as the businesses of its customers, which could reduce their demand for the Company’s services. For example, tax authorities in various states and abroad may impose taxes on the Internet-related revenue the Company generates based on regulations currently being applied to similar but not directly comparable industries.
	There are many transactions and calculations where the ultimate tax determination is uncertain. In addition, domestic and international taxation laws are subject to change. In the future, the Company may come under audit, which could result in changes to its tax estimates. The Company believes it maintains adequate tax reserves to offset potential liabilities that may arise upon audit. Although the Company believes its tax estimates and associated reserves are reasonable, the final determination of tax audits and any related litigation could be materially different than the amounts established for tax contingencies. To the extent these estimates ultimately prove to be inaccurate, the associated reserves would be adjusted, resulting in the recording of a benefit or expense in the period in which a change in estimate or a final determination is made.

	Net Loss per Share
	The Company calculates basic and diluted earnings per weighted average share based on net income (loss). The Company uses the weighted-average number of shares of common stock outstanding during the period for the computation of basic earnings per share. Diluted earnings per share include the dilutive effect of convertible stock options and restricted stock units in the weighted-average number of shares of common stock outstanding.
	The following table sets forth the components used in the computation of basic and diluted net loss per share for the periods indicated:

	Basic and diluted net loss per share	$	(0.05	)	$	(0.11	)	$	(0.20	)	$	(0.31	)
	For the three months ended September 30, 2014 and 2013, outstanding options and restricted stock units of 2,593 and 1,415, respectively, were excluded from the computation of diluted net loss per share because including them would have been anti-dilutive.
	For the nine months ended September 30, 2014 and 2013, outstanding options and restricted stock units of 2,323 and 1,689, respectively, were excluded from the computation of diluted net loss per share because including them would have been anti-dilutive.

	During the nine months ended September 30, 2013, the Company purchased and canceled approximately 2,300 shares for approximately $5,512, including commissions and expenses under a previously authorized share repurchase program. All repurchased shares were canceled and returned to authorized but unissued status.
	In June 2013, the Company’s stockholders approved the Company’s 2013 Employee Stock Purchase Plan (ESPP). The ESPP allows participants to purchase the Company’s common stock at a 15% discount of the lower of the beginning or end of the offering period using the closing price on that day. During the nine months ended September 30, 2014, the Company issued 141 shares under the ESPP. Total cash proceeds from the purchase of shares under the ESPP were approximately $235. As of September 30, 2014, shares reserved for issuance to employees under this plan totaled 4,000 and the Company held employee contributions of $210, (included in other current liabilities) for future purchases under the ESPP. The ESPP is considered compensatory. The Company recorded compensation expense of $41 and $128 during the three and nine months ended September 30, 2014, respectively, related to the ESPP.

	Income Taxes
	Income taxes for the interim periods presented have been included in the accompanying consolidated financial statements on the basis of an estimated annual effective tax rate. Based on an estimated annual effective tax rate and discrete items, the income tax expense for the three and nine months ended September 30, 2014 was $98 and $181, respectively. Income tax expense on the loss from continuing operations before taxes was different than the statutory income tax rate primarily due to the Company providing for a valuation allowance on deferred tax assets in certain jurisdictions, and the recording of state and foreign tax expense for the three and nine month periods.
	The Company files income tax returns in jurisdictions with varying statues of limitations. Tax years 2010 through 2013 generally remain subject to examination by federal and most state tax authorities. As of September 30, 2014, the Company is not under any federal or state examination.
	On September 13, 2013, the Internal Revenue Service released final tangible property regulations under Sections 162(a) and 263(a) of the Internal Revenue Code of 1986 (Code), regarding the deduction and capitalization of expenditures related to tangible property. The final regulations replace temporary regulations that were issued in December 2011. Also released were proposed regulations under Section 168 of the Code regarding dispositions of tangible property. Early adoption was available; however, the Company did not elect to early adopt the regulations. The Company adopted the regulations on January 1, 2014, and does not believe there has been or will be a material impact on its consolidated financial statements.

These include money market funds, commercial paper, corporate notes and bonds, U.S. government agency bonds, and publicly traded stocks, which are classified as either cash and cash equivalents or marketable securities.
	The Company’s financial assets are valued using market prices on both active markets (level 1) and less active markets (level 2). Level 1 instrument valuations are obtained from real-time quotes for transactions in active exchange markets involving identical assets. Level 2 instrument valuations are obtained from readily available pricing sources for comparable instruments or identical instruments in less active markets. Level 3 inputs are valued using models that take into account the terms of the arrangement as well as multiple inputs where applicable, such as estimated units sold and other customer utilization metrics.

	The carrying amount of cash equivalents approximates fair value because their maturity is less than three months. The carrying amount of short-term and long-term marketable securities approximates fair value as the securities are marked to market as of each balance sheet date with any unrealized gains and losses reported in stockholders’ equity. The carrying amount of accounts receivable, accounts payable and accrued liabilities approximates fair value due to the short-term maturity of the amounts.

Accounting Policies [Abstract]	'
Basis of Presentation	'
	Basis of Presentation
	The accompanying unaudited interim consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. They do not include all of the information and footnotes required by U.S. generally accepted accounting principles (U.S. GAAP) for complete financial statements. Such interim financial information is unaudited but reflects all adjustments that, in the opinion of management, are necessary for the fair presentation of the interim periods presented. All such adjustments are, in the opinion of management, of a normal recurring nature. The results of operations presented in this quarterly report on Form 10-Q are not necessarily indicative of the results that may be expected for the year ending December 31, 2014 or for any future periods. This quarterly report on Form 10-Q should be read in conjunction with the Company’s audited financial statements and footnotes included in its annual report on Form 10-K for the fiscal year ended December 31, 2013.
	The consolidated financial statements include accounts of the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated. In addition, certain other reclassifications have been made to prior year amounts to conform to the current year presentation.
	During the three months ended September 30, 2014, the Company recorded an immaterial error correction of approximately $1,100 relating to previous over billings by a co-location provider.  This correction was recorded as a reduction of costs of revenues.
Revision of Previously Issued Financial Statements	'
	Revision of Previously Issued Financial Statements
	As previously disclosed in our 2013 Form 10-K, the consolidated statement of operations was revised to reclassify certain amounts to cost of revenues that were previously reported in general and administrative expenses for the three and nine months ended September 30, 2013.
Use of Estimates	'
	Use of Estimates
	The preparation of the consolidated financial statements and related disclosures in conformity with U.S. GAAP requires management to make judgments, assumptions, and estimates that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results and outcomes may differ from those estimates. The results of operations presented in this quarterly report on Form 10-Q are not necessarily indicative of the results that may be expected for the year ending December 31, 2014 or for any other future periods.
Recent Accounting Pronouncements	'
	Recent Accounting Standards
	Recently Issued Accounting Pronouncements
	In April 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-08, which includes amendments that change the requirements for reporting discontinued operations and require additional disclosures about discontinued operations. Under the new guidance, only disposals representing a strategic shift in operations - that is, a major effect on the organization's operations and financial results - should be presented as discontinued operations. Examples include a disposal of a major geographic area, a major line of business, or a major equity method investment. Additionally, this ASU requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income, and expenses of discontinued operations. This update is effective for the Company in the first quarter of 2015. The new guidance would only impact the Company upon the disposal of a business.
	In May 2014, the FASB issued ASU 2014-09, which provides guidance for revenue recognition. The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In doing so, companies will need to use more judgment and make more estimates than under today’s guidance. These may include identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. This guidance will be effective for the Company in the first quarter of 2017. Early adoption is not permitted. The Company is currently in the process of evaluating the impact of adoption of this ASU on its consolidated financial statements.
	In August 2014, the FASB issued ASU 2014-15, which provides guidance for disclosure of uncertainties about an entity’s ability to continue as a going concern. ASU 2014-15 defines management's responsibility to assess an entity's ability to continue as a going concern, and to provide related footnote disclosures in certain circumstances. This guidance will be effective for the Company in the first annual period ending after December 15, 2016; however, early adoption is permitted. The Company does not expect the adoption of this guidance to have a material impact on its consolidated financial statements.
