NATURE OF OPERATIONS AND BASIS OF PRESENTATION	NATURE OF OPERATIONS AND BASIS OF PRESENTATION Internap Corporation (“we,” “us,” “our,” “INAP,” or “the Company”) provides high-performance data center services including colocation, managed hosting, cloud and network services. INAP partners with its customers, who range from the Fortune 500 to emerging start-ups, to create secure, scalable and reliable IT infrastructure solutions that meet the customer’s unique business requirements. INAP operates in 57 primarily Tier 3 data centers in 21 metropolitan markets and has 98 POPs around the world. INAP has over 1 million gross square feet under lease, with over 500,000 square feet of data center space. We have prepared the accompanying unaudited condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information. These financial statements include all of our accounts and those of our wholly-owned subsidiaries. We have eliminated all intercompany transactions and balances in the accompanying financial statements. In the opinion of management, all adjustments necessary for a fair presentation of the interim results have been reflected therein. All such adjustments were of a normal and recurring nature, with the exception of those related to the adoption of Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASC 606”). Prior year amounts have been reclassified in some cases to conform to the current year presentation. We have condensed or omitted certain information and note disclosures normally included in annual financial statements prepared in accordance with GAAP. The accompanying financial statements reflect all adjustments, which consist of normal recurring adjustments unless otherwise disclosed, necessary for a fair statement of our financial position as of March 31, 2018 and our operating results and cash flows for the interim periods presented. The balance sheet at December 31, 2017 was derived from our audited financial statements, but does not include all disclosures required by GAAP. You should read the accompanying financial statements and the related notes in conjunction with our financial statements and notes thereto contained in our Annual Report on Form 10-K for the year ended December 31, 2017 filed with the Securities and Exchange Commission (“SEC”). The preparation of financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. Actual results may differ materially from these estimates. The results of operations for the three months ended March 31, 2018 are not necessarily indicative of the results that may be expected for the 2018 fiscal year or any future periods.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
RECENT ACCOUNTING PRONOUNCEMENTS	RECENT ACCOUNTING PRONOUNCEMENTS Adoption of New Accounting Standards On August 26, 2016, the Financial Accounting Standard Board (the "FASB") issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments ("ASU 2016-15"), a consensus of the FASB’s Emerging Issues Task Force. The new guidance is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. We adopted ASU 2016-15 in the first quarter of 2018 and it did not impact our consolidated financial statements. On November 17, 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash ("ASU 2016-18"), a consensus of the FASB’s Emerging Issues Task Force. The new standard requires that the statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Entities will also be required to reconcile such total to amounts on the balance sheet and disclose the nature of the restrictions. We adopted ASU 2016-18 in the first quarter of 2018 and it did not impact our consolidated financial statements. On January 5, 2017, the FASB issued final guidance that revises the definition of a business, ASU No. 2017-01: Clarifying the Definition of a Business (Topic 805) ("ASU 2017-01"). The definition of a business affects many areas of accounting (e.g., acquisitions, disposals, goodwill impairment, consolidation). The guidance requires an entity to evaluate if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets; if so, the set of transferred assets and activities is not a business. The guidance also requires a business to include at least one substantive process and narrows the definition of outputs by more closely aligning it with how outputs are described in ASC 606. We adopted ASU 2017-01 in the first quarter of 2018 and it did not impact our consolidated financial statements. On May 10, 2017, the FASB issued guidance ASU No. 2017-09: Scope of Modification Accounting (Topic 718) ("ASU 2017-09"), to clarify when to account for a change to the terms or conditions of a share-based payment award as a modification. Under the new guidance, modification accounting is required only if the fair value, the vesting conditions, or the classification of the award (as equity or liability) changes as a result of the change in terms or conditions. We adopted ASU 2017-9 in the first quarter of 2018 and it did not impact our consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09") to clarify the principles of recognizing revenue. Under this ASU, revenue is recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, ASU 2014-09 requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The Company adopted ASU 2014-09 on January 1, 2018, using the modified retrospective method. Following the adoption of ASU 2014-09, the revenue recognition for our sales arrangements remained materially consistent with our historical practice. Together with the ASU No. 2014-09, we also adopted ASU No. 2016-10, Revenue from Contracts with Customers : Identifying Performance Obligations and Licensing (Topic 606) ("ASU 2016-10") , that amended the above new revenue recognition guidance on accounting for licenses of intellectual property and identifying performance obligations. In addition, we adopted Accounting Standard Update 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients ("ASU 2016-12"). The amendment clarified that, for a contract to be considered completed at transition, all (or substantially all) of the revenue must have been recognized under legacy GAAP. It also clarified how an entity should evaluate the collectability threshold and when an entity can recognize nonrefundable consideration received as revenue if an arrangement does not meet the standard’s contract criteria. Accounting Pronouncements Issued But Not Yet Effective In February 2016, the FASB issued ASU No. 2016-02, Leases ("ASU 2016-02"), which requires all leases in excess of 12 months to be recognized on the balance sheet as lease assets and lease liabilities. For operating leases, a lessee is required to recognize a right-of-use asset and lease liability, initially measured at the present value of the lease payment; recognize a single lease cost over the lease term generally on a straight-line basis; and classify all cash payments within operating activities on the cash flow statement. The guidance is effective for annual and interim periods beginning after December 15, 2018. Earlier adoption is permitted. The Company has identified a project team and commenced an initial impact assessment process for ASU 2016-02. We are continuing to work towards establishing policies, updating our processes and implementing necessary changes to data and processes to be able to comply with the new requirements. Based on the results of our assessment to date, we anticipate this standard will have an impact, which could be significant, on our consolidated financial statements. While we are continuing to assess all potential impacts of the standard, we currently believe the most significant impact relates to recognition of a right-of-use asset and lease liability. The lease liability will be initially measured at the present value of the lease payment; the asset will be based on the liability, subject to adjustment, such as for initial direct costs. Consistent with current guidance, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification. For income statement purposes, operating leases will result in a straight line expense while finance leases will result in a front-loaded expense pattern. The Company currently plans to adopt this standard using the modified retrospective transition approach with optional practical expedients. The Company is continuing to assess all potential impacts of the standard, the impact of the standard on current accounting policies, practices and system of internal controls, in order to identify material differences, if any, that would result from applying the new requirements.

Revenue from Contract with Customer [Abstract]
REVENUES	REVENUES Upon adoption of ASC 606, the Company applied certain transition practical expedients available for modified retrospective adoption. The Company adopted the practical expedient for the portfolio approach of contracts with similar characteristics in which the company reasonably expects that the effects on the financial statements of applying this practical expedient to the portfolio would not differ materially from applying this guidance to the individual contracts (or performance obligations) within that portfolio. The Company also adopted the practical expedient to not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less, (ii) contracts for which INAP recognizes revenue at the amount to which the Company has the right to invoice for services performed, and (iii) the value for variable consideration that is applied to individual performance obligations in a series. The Company elected to exclude from the measurement of the transaction price all taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected by the entity from a customer (for example, sales, use, and value added taxes). Changes in Accounting Policies The most significant impact of the adoption of the new standard is the requirement for incremental costs to obtain a customer, such as commissions, which previously were expensed as incurred, to be deferred and amortized over the period of contract performance or a longer period if renewals are expected and the renewal commission is not commensurate with the initial commission. In addition, installation revenues are recognized over the initial contract life rather than over the estimated customer life, as they are not significant to the total contract and therefore do not represent a material right. Most performance obligations, with the exception of certain sales of equipment or hardware, are satisfied over time as the customer consumes the benefits as we perform. For equipment and hardware sales, the performance obligation is satisfied when control transfers to the customer. The Company exercised more judgment in deferring installation revenue as well as expense fulfillment and commission costs over the appropriate life. With the exception of the revenues noted above, revenue recognition remains materially consistent with historical practice. However, neither caused a material difference in the financial statement.

The Company accounts for revenue in accordance with ASC 606. Revenue is recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company enters into contracts that can include various combinations of products and services, which are generally capable of being distinct and accounted for as separate performance obligations. The Company’s contracts with customers often include performance obligations to transfer multiple products and services to a customer. Common performance obligations of the Company include delivery of services, which are discussed in more detail below. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together requires significant judgment by the Company. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account in ASC 606. A contracts transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. Total transaction price is estimated for impact of variable consideration, such as INAP’s service level arrangements ("SLA"), additional usage and late fees, discounts and promotions, and customer care credits. The majority of our contracts have multiple performance obligations, as the promise to transfer individual goods or services is separately identifiable from other promises in the contracts and, therefore, is distinct. For contracts with multiple performance obligations, we allocate the contracts transaction price to each performance obligation based on its relative standalone selling price. The stand-alone selling price (“SSP”) is determined based on observable price. In instances where the SSP is not directly observable, such as when the Company does not sell the product or service separately, INAP determines the SSP using information that may include market conditions and other observable inputs. The Company typically has more than one SSP for individual products and services due to the stratification of those products and services by customers and circumstances. In these instances, the Company may use information such as the size of the customer and geographic region in determining the SSP. Revenue by source, with sales and usage-based taxes excluded, is as follows (in thousands, unaudited): Three Months Ended March 31, 2018 INAP US INAP INTL Colocation $ 30,936 $ 1,517 Network services 13,820 2,971 Cloud 12,320 12,637 $ 57,076 $ 17,125 Revenue by geography is as follows (in thousands, unaudited): Three Months Ended March 31, 2018 INAP US INAP INTL United States $ 57,076 $ — Canada — 9,291 Other countries — 7,834 $ 57,076 $ 17,125 For the three months ended March 31, 2018, revenue recognized that was included in the contract liability balance at the beginning of each year was $0.5 million . Management expects that fulfillment costs and commission fees paid to sales representative as a result of obtaining service contracts and contract renewals are recoverable and therefore the Company capitalized them as contract costs in the amount of $26.3 million at March 31, 2018. Capitalized fulfillment and commission fees are amortized on a straight-line basis over the determined life, which vary based on the customer segment. For the three months ended March 31, 2018, amortization recognized was $2.9 million . There was no impairment loss in relation to the costs capitalized. Applying the practical expedient pertaining to contract costs, the Company recognizes the incremental costs of obtaining contracts as an expense when incurred if the amortization period of the assets that the Company otherwise would have recognized is one year or less. These costs are included in selling, general and administrative expenses.

Change In Organizational Structure And Realignment Of Expenses [Abstract]
CHANGE IN ORGANIZATIONAL STRUCTURE	CHANGE IN ORGANIZATIONAL STRUCTURE During the three months ended March 31, 2018 , we changed our organizational structure in an effort to create more effective and efficient operations and to improve customer and product focus. In that regard, we revised the information that our chief executive officer, who is also our Chief Operating Decision Maker (“CODM”), regularly reviews for purposes of allocating resources and assessing performance. As a result, we report our financial performance based on our revised segment structure, described in more detail note 11 “Operating Segments.” We have reclassified prior period amounts to conform to the current presentation.

ACQUISITION	ACQUISITION On February 28, 2018, the Company acquired SingleHop LLC ("SingleHop"), a provider of high-performance data center services including colocation, managed hosting, cloud and network services for $132.0 million net of working capital adjustments, liabilities assumed, and net of cash acquired. The transaction was funded with an incremental term loan and cash from the balance sheet. As part of the financing, INAP obtained an amendment to its credit agreement to allow for the incremental term loan and to provide further operational flexibility under the credit agreement covenants. The amendments to the credit agreement are described in more detail in note 8, "Debt". SingleHop is a recognized leader in the Managed Hosting and Infrastructure as a Service (IaaS) business segment, offering highly automated and on-demand IT infrastructure. This strategic combination allows INAP to immediately offer its customers advanced products and expertise. SingleHop’s enterprise and business customers will also benefit from INAP’s North America and global presence, providing a more expansive integrated footprint. The Company determined the preliminary fair value of the net assets acquired as follows (in thousands): Purchase price allocation Cash $ 2,857 Prepaid expenses and other assets 1,683 Property, plant and equipment 14,885 Other long term assets 39 Intangible assets: Weighted Average Noncompete Agreements 4,000 4 years Trade name 1,700 8 years Technology 15,100 7 years Customer relationship 34,100 10 years Goodwill 67,868 Total assets acquired 142,232 Accounts payable and accrued liabilities 5,098 Deferred revenue 1,600 Long term liabilities 534 Net assets acquired $ 135,000 The goodwill recorded in connection with this acquisition was based on operating synergies and other benefits expected to result from the combined operations and the assembled workforce acquired. The goodwill acquired is deductible for tax purposes. Acquisition-related costs recognized during the three months ended March 31, 2018 including transaction costs such as legal, accounting, valuation and other professional services, were $2.5 million and are included in "Sales, general and administrative" expenses on the accompanying unaudited condensed consolidated statements of operations and comprehensive loss.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS We account for certain assets and liabilities at fair value. The hierarchy below lists three levels of fair value based on the extent to which inputs used in measuring fair value are observable in the market. We categorize each of our fair value measurements in one of these three levels based on the lowest level input that is significant to the fair value measurement in its entirety. These levels are: • Level 1: Quoted prices in active markets for identical assets or liabilities; • Level 2: Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and • Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Assets and liabilities measured at fair value on a recurring basis are summarized as follows (in thousands): Level 1 Level 2 Level 3 Total March 31, 2018 Cash and cash equivalents $ 16,159 $ — $ — $ 16,159 Asset retirement obligations (1) — — 1,729 1,729 December 31, 2017 Cash and cash equivalents 14,603 — — 14,603 Asset retirement obligations (1) — — 1,936 1,936 (1) We calculate the fair value of asset retirement obligations by discounting the estimated amount using the current Treasury bill rate adjusted for our credit risk. At March 31, 2018, the balance is included in “Other long-term liabilities,” in the accompanying unaudited consolidated balance sheets. At December 31, 2017, $0.2 million and $1.7 million were included in "Other current liabilities" and "Other long-term liabilities," respectively, in the accompanying unaudited consolidated balance sheets.

GOODWILL AND OTHER INTANGIBLE ASSETS	GOODWILL AND OTHER INTANGIBLE ASSETS Goodwill During the three months ended March 31, 2018 , we changed our operating segments, as discussed in note 4 “Change in Organizational Structure,” and, subsequently, our reporting units. We now have seven reporting units: US Colocation, US Cloud, US Network, INT Colocation, INT Cloud, INT Network, and Ubersmith. We allocated goodwill to our new reporting units using a relative fair value approach. In addition, we completed an assessment of any potential goodwill impairment for all reporting units immediately prior to and after the reallocation and determined that no impairment existed.

DEBT

Debt Disclosure [Abstract]
DEBT	DEBT Credit Agreement On April 6, 2017, we entered into a new Credit Agreement (the “2017 Credit Agreement”), which provides for a $300 million term loan facility ("2017 term loan") and a $25 million revolving credit facility (the "2017 revolving credit facility"). The proceeds of the term loan were used to refinance the Company’s existing credit facility and to pay costs and expenses associated with the 2017 Credit Agreement. Certain portions of refinancing transaction were considered an extinguishment of debt and certain portions were considered a modification. A total of $5.7 million was paid for debt issuance costs related to the 2017 Credit Agreement. Of the $5.7 million in costs paid, $1.9 million related to the exchange of debt and was expensed, $3.3 million related to term loan third party costs and will be amortized over the term of the loan and $0.4 million are prepaid debt issuance costs related to the revolving credit facility and will be amortized over the term of the revolving credit facility. In addition, $4.8 million of debt discount and debt issuance costs related to the previous credit facility were expensed due to the extinguishment of that credit facility. The maturity date of the term loan is April 6, 2022 and the maturity date of the 2017 revolving credit facility is October 6, 2021. As of March 31, 2018, the balance of the term loan and the revolver was $432.4 million and $16.0 million , respectively. As of March 31, 2018, the interest rate on the 2017 term loan and the revolver was 8.72% and 8.88% , respectively. Borrowings under the amended credit agreement bear interest at a rate per annum equal to an applicable margin plus, at our option, a base rate or an adjusted LIBOR rate. The applicable margin for loans under the revolving credit facility is 4.5% for loans bearing interest calculated using the base rate (“Base Rate Loans”) and 5.50% for loans bearing interest calculated using the adjusted LIBOR rate (“Adjusted LIBOR Loans”). The applicable margin for loans under the term loan is 5.00% for Base Rate Loans and 6.00% for Adjusted LIBOR Rate loans. The base rate is equal to the highest of (a) the adjusted U.S. Prime Lending Rate as published in the Wall Street Journal, (b) with respect to term loans issued on the closing date, 2.00% , (c) the federal funds effective rate from time to time, plus 0.50% , and (d) the adjusted LIBOR rate, as defined below, for a one-month interest period, plus 1.00% . The adjusted LIBOR rate is equal to the rate per annum (adjusted for statutory reserve requirements for Eurocurrency liabilities) at which Eurodollar deposits are offered in the interbank Eurodollar market for the applicable interest period (one, two, three or six months), as quoted on Reuters screen LIBOR (or any successor page or service). The financing commitments of the Lenders extending the revolving credit facility are subject to various conditions, as set forth in the credit agreement. First Amendment On June 28, 2017, the Company entered into an amendment to the 2017 Credit Agreement (“First Amendment”), by and among the Company, each of the lenders party thereto, and Jefferies Finance LLC, as Administrative Agent. The First Amendment clarified that for all purposes the Company’s liabilities pursuant to any lease that was treated as rental and lease expense, and not as a capital lease obligation or indebtedness on the closing date of the 2017 Credit Agreement, would continue to be treated as a rental and lease expense, and not as a capital lease obligations or indebtedness, for all purposes of the 2017 Credit Agreement, notwithstanding any amendment of the lease that results in the treatment of such lease as a capital lease obligation or indebtedness for financial reporting purposes. Second Amendment On February 6, 2018, the Company, the Lenders party thereto and Jefferies Finance LLC, as Administrative Agent, entered into a Second Amendment to Credit Agreement (the “Second Amendment”) that amended the 2017 Credit Agreement. The Second Amendment, among other things, amends the 2017 Credit Agreement (i) to permit the Company to incur incremental term loans under the 2017 Credit Agreement of up to $135 million to finance the Company’s acquisition of SingleHop and to pay related fees, costs and expenses and (ii) to revise the maximum total net leverage ratio and minimum consolidated interest coverage ratio covenants. The financial covenant amendments became effective upon the consummation of the SingleHop acquisition, while the other provisions of the 2018 Second Amendment became effective upon the execution and delivery of the Second Amendment. At March 31, 2018, the Company has been in compliance with the covenants. A total of $1.0 million was paid for debt issuance costs related to the Second Amendment. Of the $1.0 million in costs paid, $0.2 million related to the payment of legal and professional which were expensed, $0.8 million related to term loan lender fees and will be amortized over the term of the loan. Third Amendment On February 28, 2018, INAP entered into the Incremental and Third Amendment to the Credit Agreement among the Company, the Lenders party thereto and Jefferies Finance LLC, as Administrative Agent (the “Third Amendment”). The Third Amendment provides for a new incremental term loan facility under the 2017 Credit Agreement of $135 million (the “Incremental Term Loan”). The Incremental Term Loan has terms and conditions identical to the existing loans under the 2017 Credit Agreement, as amended. Proceeds of the Incremental Term Loan were used to complete the acquisition of SingleHop and to pay fees, costs and expenses related to the acquisition, the Third Amendment and the Incremental Term Loan. This transaction was considered a modification. A total of $5.0 million was paid for debt issuance costs related to the First Amendment. Of the $5.0 million in costs paid, $0.1 million related to the payment of legal and professional which were expensed, $4.9 million related to term loan lender fees and will be amortized over the term of the loan.

Segment Reporting [Abstract]
OPERATING SEGMENTS	OPERATING SEGMENTS The Company has two reportable segments: INAP US and INAP INTL. These segments are comprised of strategic businesses that are defined by the location of the service offerings. Our INAP US segment consists of US Colocation, US Cloud, and US Network services based in the United States. Our INAP INTL segment consists of these same services based in countries other than the United States, and Ubersmith. Each segment is managed as an operation with well-established strategic directions and performance requirements. Each segment is led by a separate General Manager who reports directly to the Company’s CODM. The CODM evaluates segment performance using business unit contribution which is defined as business unit revenues less direct costs of sales and services, customer support, and sales and marketing, exclusive of depreciation and amortization. Our services, which are included within both our reportable segments, are described as follows: Colocation Colocation involves providing physical space within data centers and associated services such as power, interconnection, environmental controls, monitoring and security while allowing our customers to deploy and manage their servers, storage and other equipment in our secure data centers. We design the data center infrastructure, procure the capital equipment, deploy the infrastructure and are responsible for the operation and maintenance of the facility. Cloud Cloud services involve providing compute resources and storage services on demand via an integrated platform that includes our automated bare metal solutions. We offer our next generation cloud platforms in our high density colocation facilities and utilize the INAP performance IP for low latency connectivity. Network Network services includes our patented Performance IP™ service, content delivery network services, IP routing hardware and software platform. By intelligently routing traffic with redundant, high-speed connections over multiple, major Internet backbones, our IP connectivity provides high-performance and highly-reliable delivery of content, applications and communications to end users globally. We deliver our IP connectivity through 97 POPs around the world.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Basis of Presentation	We have prepared the accompanying unaudited condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information. These financial statements include all of our accounts and those of our wholly-owned subsidiaries. We have eliminated all intercompany transactions and balances in the accompanying financial statements. In the opinion of management, all adjustments necessary for a fair presentation of the interim results have been reflected therein. All such adjustments were of a normal and recurring nature, with the exception of those related to the adoption of Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASC 606”). Prior year amounts have been reclassified in some cases to conform to the current year presentation. We have condensed or omitted certain information and note disclosures normally included in annual financial statements prepared in accordance with GAAP. The accompanying financial statements reflect all adjustments, which consist of normal recurring adjustments unless otherwise disclosed, necessary for a fair statement of our financial position as of March 31, 2018 and our operating results and cash flows for the interim periods presented. The balance sheet at December 31, 2017 was derived from our audited financial statements, but does not include all disclosures required by GAAP. You should read the accompanying financial statements and the related notes in conjunction with our financial statements and notes thereto contained in our Annual Report on Form 10-K for the year ended December 31, 2017 filed with the Securities and Exchange Commission (“SEC”).
Use of Estimates	The preparation of financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. Actual results may differ materially from these estimates. The results of operations for the three months ended March 31, 2018 are not necessarily indicative of the results that may be expected for the 2018 fiscal year or any future periods.
Recent Accounting Pronouncements	Adoption of New Accounting Standards On August 26, 2016, the Financial Accounting Standard Board (the "FASB") issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments ("ASU 2016-15"), a consensus of the FASB’s Emerging Issues Task Force. The new guidance is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. We adopted ASU 2016-15 in the first quarter of 2018 and it did not impact our consolidated financial statements. On November 17, 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash ("ASU 2016-18"), a consensus of the FASB’s Emerging Issues Task Force. The new standard requires that the statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Entities will also be required to reconcile such total to amounts on the balance sheet and disclose the nature of the restrictions. We adopted ASU 2016-18 in the first quarter of 2018 and it did not impact our consolidated financial statements. On January 5, 2017, the FASB issued final guidance that revises the definition of a business, ASU No. 2017-01: Clarifying the Definition of a Business (Topic 805) ("ASU 2017-01"). The definition of a business affects many areas of accounting (e.g., acquisitions, disposals, goodwill impairment, consolidation). The guidance requires an entity to evaluate if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets; if so, the set of transferred assets and activities is not a business. The guidance also requires a business to include at least one substantive process and narrows the definition of outputs by more closely aligning it with how outputs are described in ASC 606. We adopted ASU 2017-01 in the first quarter of 2018 and it did not impact our consolidated financial statements. On May 10, 2017, the FASB issued guidance ASU No. 2017-09: Scope of Modification Accounting (Topic 718) ("ASU 2017-09"), to clarify when to account for a change to the terms or conditions of a share-based payment award as a modification. Under the new guidance, modification accounting is required only if the fair value, the vesting conditions, or the classification of the award (as equity or liability) changes as a result of the change in terms or conditions. We adopted ASU 2017-9 in the first quarter of 2018 and it did not impact our consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09") to clarify the principles of recognizing revenue. Under this ASU, revenue is recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, ASU 2014-09 requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The Company adopted ASU 2014-09 on January 1, 2018, using the modified retrospective method. Following the adoption of ASU 2014-09, the revenue recognition for our sales arrangements remained materially consistent with our historical practice. Together with the ASU No. 2014-09, we also adopted ASU No. 2016-10, Revenue from Contracts with Customers : Identifying Performance Obligations and Licensing (Topic 606) ("ASU 2016-10") , that amended the above new revenue recognition guidance on accounting for licenses of intellectual property and identifying performance obligations. In addition, we adopted Accounting Standard Update 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients ("ASU 2016-12"). The amendment clarified that, for a contract to be considered completed at transition, all (or substantially all) of the revenue must have been recognized under legacy GAAP. It also clarified how an entity should evaluate the collectability threshold and when an entity can recognize nonrefundable consideration received as revenue if an arrangement does not meet the standard’s contract criteria. Accounting Pronouncements Issued But Not Yet Effective In February 2016, the FASB issued ASU No. 2016-02, Leases ("ASU 2016-02"), which requires all leases in excess of 12 months to be recognized on the balance sheet as lease assets and lease liabilities. For operating leases, a lessee is required to recognize a right-of-use asset and lease liability, initially measured at the present value of the lease payment; recognize a single lease cost over the lease term generally on a straight-line basis; and classify all cash payments within operating activities on the cash flow statement. The guidance is effective for annual and interim periods beginning after December 15, 2018. Earlier adoption is permitted. The Company has identified a project team and commenced an initial impact assessment process for ASU 2016-02. We are continuing to work towards establishing policies, updating our processes and implementing necessary changes to data and processes to be able to comply with the new requirements. Based on the results of our assessment to date, we anticipate this standard will have an impact, which could be significant, on our consolidated financial statements. While we are continuing to assess all potential impacts of the standard, we currently believe the most significant impact relates to recognition of a right-of-use asset and lease liability. The lease liability will be initially measured at the present value of the lease payment; the asset will be based on the liability, subject to adjustment, such as for initial direct costs. Consistent with current guidance, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification. For income statement purposes, operating leases will result in a straight line expense while finance leases will result in a front-loaded expense pattern. The Company currently plans to adopt this standard using the modified retrospective transition approach with optional practical expedients. The Company is continuing to assess all potential impacts of the standard, the impact of the standard on current accounting policies, practices and system of internal controls, in order to identify material differences, if any, that would result from applying the new requirements.
Fair Value Measurements	We account for certain assets and liabilities at fair value. The hierarchy below lists three levels of fair value based on the extent to which inputs used in measuring fair value are observable in the market. We categorize each of our fair value measurements in one of these three levels based on the lowest level input that is significant to the fair value measurement in its entirety. These levels are: • Level 1: Quoted prices in active markets for identical assets or liabilities; • Level 2: Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and • Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
Operating Segments	The Company has two reportable segments: INAP US and INAP INTL. These segments are comprised of strategic businesses that are defined by the location of the service offerings. Our INAP US segment consists of US Colocation, US Cloud, and US Network services based in the United States. Our INAP INTL segment consists of these same services based in countries other than the United States, and Ubersmith. Each segment is managed as an operation with well-established strategic directions and performance requirements. Each segment is led by a separate General Manager who reports directly to the Company’s CODM. The CODM evaluates segment performance using business unit contribution which is defined as business unit revenues less direct costs of sales and services, customer support, and sales and marketing, exclusive of depreciation and amortization.
Net Loss Per Share	We compute basic net loss per share by dividing net loss attributable to our common stockholders by the weighted average number of shares of common stock outstanding during the period. We exclude all outstanding options and unvested restricted stock as such securities are anti-dilutive for all periods presented.
