Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	Basis of Presentation and Significant Accounting Policies Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared by Equinix, Inc. ("Equinix" or the "Company") and reflect all adjustments, consisting only of normal recurring adjustments, which in the opinion of management are necessary to fairly state the financial position and the results of operations for the interim periods presented. The condensed consolidated balance sheet data as of December 31, 2019 has been derived from audited consolidated financial statements as of that date. The condensed consolidated financial statements have been prepared in accordance with the regulations of the Securities and Exchange Commission ("SEC"), but omit certain information and footnote disclosure necessary to present the statements in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP"). For further information, refer to the Consolidated Financial Statements and Notes thereto included in Equinix's Form 10-K as filed with the SEC on February 21, 2020. Results for the interim periods are not necessarily indicative of results for the entire fiscal year. Consolidation The accompanying unaudited condensed consolidated financial statements include the accounts of Equinix and its subsidiaries, including the acquisitions of Packet Host, Inc. from March 2, 2020, three data centers in Mexico acquired from Axtel S.A.B. de C.V from January 8, 2020, and Switch Datacenters' AMS1 data center business in Amsterdam, Netherlands from April 18, 2019. All intercompany accounts and transactions have been eliminated in consolidation. Income Taxes The Company elected to be taxed as a real estate investment trust for U.S. federal income tax purposes ("REIT") beginning with its 2015 taxable year. As a result, the Company may deduct the distributions made to its stockholders from taxable income generated by the Company and its qualified REIT subsidiaries ("QRSs"). The Company's dividends paid deduction generally eliminates the U.S. federal taxable income of the Company and its QRSs, resulting in no U.S. federal income tax due. However, the Company's domestic taxable REIT subsidiaries ("TRSs") are subject to U.S. corporate income taxes on any taxable income generated by them. In addition, the foreign operations of the Company are subject to local income taxes regardless of whether the foreign operations are operated as QRSs or TRSs. The Company provides for income taxes during interim periods based on the estimated effective tax rate for the year. The effective tax rate is subject to change in the future due to various factors such as the operating performance of the Company, tax law changes and future business acquisitions. The Company's effective tax rates were 20.2% and 26.6% for the three months ended March 31, 2020 and 2019 , respectively. Coronavirus (COVID-19) Update In December 2019, a novel strain of coronavirus, referred to as Coronavirus disease 2019, or COVID-19, emerged. On February 29, 2020, the World Health Organization (“WHO”) raised the COVID-19 threat from high to very high, and on March 11, 2020, the WHO characterized COVID-19 as a global pandemic. The extent to which the Company’s operations will be impacted by COVID-19 will depend largely on future developments, which are highly uncertain and cannot be accurately predicted, including new information which may emerge concerning the severity of the outbreak and actions by government authorities to contain the outbreak or treat its impact, among other things. As of the date of issuance of the financial statements, the Company is not aware of any specific event or circumstance that would require it to update its estimates, judgments or revise the carrying value of its assets or liabilities. These estimates may change, as new events occur and additional information is obtained, and will be recognized in the condensed consolidated financial statements as soon as they become known. Actual results could differ from these estimates. Recent Accounting Pronouncements Accounting Standards Not Yet Adopted In December 2019, Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2019-12, Income Taxes ("Topic 740"): Simplifying the Accounting for Income T axes. The ASU simplifies accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The ASU also improves consistent application of and simplifies generally accepted accounting principles ("GAAP") for other areas of Topic 740 by clarifying and amending existing guidance. For public entities, the ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted including adoption in any interim period for periods for which financial statements have not yet been issued. The Company is currently evaluating the extent of the impact that the adoption of this standard will have on its condensed consolidated financial statements. Accounting Standards Adopted In March 2020, FASB issued ASU 2020-04, Reference Rate Reform ("Topic 848"): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The ASU provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The ASU is effective for all entities as of March 12, 2020 through December 31, 2022. The Company adopted the ASU upon its issuance and there was no impact on the Company's condensed consolidated financial statements for the three months ended March 31, 2020 as a result of adopting this standard. The Company will evaluate its debt, derivative and lease contracts that are eligible for modification relief and may apply the elections prospectively as needed. In June 2016, FASB issued ASU 2016-13, Financial Instruments - Credit Losses ("Topic 326"): Measurement of Credit Losses on Financial Instruments. The ASU requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. The ASU requires enhanced qualitative and quantitative disclosures to help investors and other financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization's portfolio. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted. The Company adopted this new ASU on January 1, 2020 using the modified retrospective approach and recorded a net decrease to retained earnings of $ 0.9 million and a corresponding increase to allowance for doubtful accounts. The adoption did not have any significant impact on other financial assets within the scope of ASC 326, such as contract asset. Accounts Receivable Accounts receivables are recorded at invoice amount and are generally due in less than one year. Allowance for doubtful accounts are estimated losses resulting from the inability of customers making payments. An estimate of uncollectible amounts is made based on historical bad debts, age of customer receivable balances, customers' financial conditions and current economic trends. As of March 31, 2020, our allowance for doubtful accounts considered the current and potential future impacts caused by the COVID-19 pandemic based on information available to such date. Accounts receivable, net, consisted of the following as of March 31, 2020 and December 31, 2019 (in thousands): March 31, December 31, Accounts receivable $ 701,946 $ 702,160 Allowance for doubtful accounts (14,793 ) (13,026 ) Accounts receivable, net $ 687,153 $ 689,134 The following table summarizes the activity of the Company's allowance for doubtful accounts (in thousands): Balance at December 31, 2019 $ 13,026 Adjustments due to adoption of ASU 2016-13 900 Provision for allowance for doubtful accounts 3,934 Net write-offs and recoveries (2,688 ) Impact of foreign currency exchange and others (379 ) Balance at March 31, 2020 $ 14,793

The amounts of revenue recognized during the three months ended March 31, 2020 from the opening deferred revenue balance as of January 1, 2020 was $38.1 million . Remaining performance obligations As of March 31, 2020 , approximately $7.2 billion of total revenues including deferred installation revenues are expected to be recognized in future periods, the majority of which will be recognized over the next 24 months . While initial contract terms vary in length, substantially all contracts thereafter automatically renew in one-year increments. Included in the remaining performance obligations is either 1) remaining performance obligations under the initial contract terms or 2) remaining performance obligations related to contracts in the renewal period once the initial terms have lapsed. The remaining performance obligations do not include variable consideration related to unsatisfied performance obligations such as the usage of metered power, service fees from xScale TM data centers, which are calculated based on future events or actual costs incurred in the future, or any contracts that could be terminated without any significant penalties such as the majority of interconnection revenues. The remaining performance obligations above include revenues to be recognized in the future related to arrangements where the Company is considered the lessor.

Business Combinations [Abstract]
Acquisitions	Acquisitions 2020 Acquisitions On March 2, 2020, the Company acquired all outstanding shares and equity awards of Packet Host, Inc. (“Packet”), a leading bare metal automation platform for a total purchase consideration of approximately $290.3 million in cash. In addition, the Company paid $16.1 million in cash to accelerate the vesting of unvested Packet equity awards for certain Packet employees, which was recorded as stock-based compensation expense during the three months ended March 31, 2020. In connection with the acquisition, the Company also issued restricted stock awards with an aggregated fair value of $30.2 million and a three -year vesting period, which will be recognized as stock-based compensation costs over the vesting period. The acquisition, combined with the Company’s o wn organic bare metal service in development, is expected to accelerate Equinix's strategy to help enterprises deploy hybrid multicloud architectures on Equinix's data center platform. On January 8, 2020, the Company completed the acquisition of three data centers in Mexico from Axtel S.A.B. de C.V. (“Axtel”) for a total purchase consideration of approximately $189.0 million , including $175.0 million in cash and $14.0 million the Company paid to the seller for recoverable value-added taxes ("VAT") incurred prior to the acquisition, which related to a corresponding VAT receivable acquired upon acquisition. The acquisition supports the Company’s ongoing expansion to meet customer demand in the Americas region. Both acquisitions constitute a business under the accounting standard for business combinations and, therefore, were accounted for as business combinations using the acquisition method of accounting. Under the acquisition method of accounting, the total purchase price is allocated to the assets acquired and liabilities assumed measured at fair value on the date of acquisition. As of March 31, 2020, the Company had not completed the detailed valuation analysis to derive the fair value of assets acquired and liabilities assumed, including property, plant and equipment, intangible assets and the related tax impacts; therefore, the purchase price allocation is based on provisional estimates and subject to continuing management analysis. A summary of the preliminary allocation of total purchase consideration is presented as follows (in thousands): Packet Axtel Cash and cash equivalents $ 1,029 $ — Accounts receivable 5,148 — Other current assets 108 14,048 Property, plant and equipment 28,980 76,407 Operating lease right-of-use assets 1,445 1,646 Intangible assets 68,600 22,750 Goodwill 223,117 78,902 Other assets 138 — Total assets acquired 328,565 193,753 Accounts payable and accrued liabilities (987 ) (238 ) Other current liabilities (826 ) — Operating lease liabilities (1,445 ) (1,586 ) Finance lease liabilities (28,980 ) — Other liabilities — (162 ) Deferred tax liabilities (6,029 ) (2,749 ) Net assets acquired $ 290,298 $ 189,018 The following table presents certain information on the acquired intangible assets (in thousands): Intangible Assets Fair Value Estimated Useful Lives (Years) Weighted-average Estimated Useful Lives (Years) Packet: Trade names $ 1,600 3.0 3.0 Existing technology 5,100 3.0 3.0 Customer relationships 61,900 10.0 10.0 Axtel: Customer relationships 22,750 15.0 15.0 The fair value of the Packet trade name was estimated using the relief from royalty method under the income approach. The Company applied a relief from royalty rate of 1.0% and a discount rate of 8.0% . The fair value of existing technology was estimated under the cost approach by projecting the cost to recreate a new asset with an equivalent utility of the existing technology. The key assumptions of the cost approach include total cost, time to recreate and functional obsolescence. The fair value of customer relationships acquired from Packet and Axtel was estimated by applying an income approach, by calculating the present value of estimated future operating cash flows generated from existing customers less costs to realize the revenue. The Company applied a discount rate of 8.0% for Packet and 13.3% for Axtel, which reflects the nature of the assets as they relate to the risk and uncertainty of the estimated future operating cash flows, as well as the risk of the country within which the acquired business operates. The fair value of property, plant and equipment was estimated by applying the cost approach, with the exception of land, which was estimated by applying the market approach. The key assumptions of the cost approach include replacement cost new, physical deterioration, functional and economic obsolescence, economic useful life, remaining useful life, age and effective age. Goodwill represents the excess of the purchase price over the fair value of the net tangible and intangible assets acquired and liabilities assumed. Goodwill is attributable to the workforce of the acquired business and the projected revenue increase expected to arise from future customers after the Packet and Axtel acquisitions. Goodwill from both acquisitions is not amortizable for local tax purposes and is attributable to the Company's Americas region. The Company incurred transaction costs of approximately $9.6 million during the three months ended March 31, 2020 for both acquisitions combined. The operating results of both acquisitions are report ed in the Americas region following the date of acquisition. During the three months ended March 31, 2020 , the Company's results of operations include $8.1 million of revenues and $13.6 million of net loss from operations from the combined operations of Packet and Axtel. The net loss was primarily attributable to the $16.1 million stock-based compensation expense incurred to accelerate the vesting of certain Packet employees’ unvested Packet equity awards at the close of the Packet acquisition. 2019 Acquisition On April 18, 2019, the Company completed the acquisition of Switch Datacenters' AMS1 data center business in Amsterdam, Netherlands, for a cash purchase price of approximately €30.6 million or approximately $34.3 million

Equity Method Investments	Equity Method Investments On October 8, 2019, the Company entered into a joint venture in the form of a limited liability partnership with GIC, Singapore's sovereign wealth fund (the "EMEA Joint Venture"), to develop and operate xScale TM data centers in Europe. xScale data centers are engineered to meet the technical and operational requirements and price points of core hyperscale workload deployments and also offer access to Equinix's comprehensive suite of interconnection and edge services. Upon closing, GIC contributed €152.6 million in cash, or $167.4 million at the exchange rate in effect on October 8, 2019, for an 80% partnership interest in the EMEA Joint Venture. Equinix sold certain xScale data center facilities to the EMEA Joint Venture in exchange for net cash proceeds of $351.8 million , as well as a 20% partnership interest in the EMEA Joint Venture with a fair value of $41.9 million . The Company accounts for its investments in the EMEA Joint Venture using the equity method of accounting, whereby the investments were recorded initially at fair value, which equals to the cost of the Company's initial equity contribution, and subsequently adjusted for cash contributions and the Company's share of the income and losses of the investees. During the three months ended March 31, 2020, the Company made an additional equity contribution of $5.1 million to the EMEA Joint Venture. As of March 31, 2020 and December 31, 2019, the Company's equity method investments were $72.7 million and $59.7 million , respectively, and were included within other assets on the consolidated balance sheet. The Company's share of the income and losses of the equity method investments was not significant for the three months ended March 31, 2020, and was included in other income on the condensed consolidated statement of operations. As part of the sale of its xScale data center facilities to the EMEA Joint Venture, the Company also received a contingent consideration receivable upon completion of certain performance milestones. The milestone payments are primarily contingent on the receipt of local regulatory approval for certain sites. The contingent consideration is considered a derivative and is remeasured at its fair value each reporting period using inputs such as probabilities of payment, discount rates, foreign currency forward rates and projected payment dates. The fair value measurements were based on significant inputs that are not observable in the market and thus represent Level 3 measurements. As of March 31, 2020 and December 31, 2019, the fair value of the contingent consideration was $38.9 million and $40.1 million

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	Derivatives and Hedging Activities Derivatives Designated as Hedging Instruments Net Investment Hedges. The Company is exposed to the impact of foreign exchange rate fluctuations on the value of investments in its foreign subsidiaries whose functional currencies are other than the U.S. Dollar. In order to mitigate the impact of foreign currency exchange rates, the Company has entered into various foreign currency debt obligations, which are designated as hedges against the Company's net investments in foreign subsidiaries. As of March 31, 2020 and December 31, 2019 , the total principal amounts of foreign currency debt obligations designated as net investment hedges were $4,245.1 million and $4,078.7 million , respectively. The Company also uses cross-currency interest rate swaps to hedge a portion of its net investment in its European operations. As of both March 31, 2020 and December 31, 2019 , U.S. Dollar to Euro cross-currency interest rate swap contracts with a total notional amount of $750.0 million were outstanding, with maturity dates in April 2022, January 2024 and January 2025. At maturity of each outstanding contract, the Company will receive U.S. Dollars from and pay Euros to the contract counterparty. During the term of each contract, the Company receives interest payments in U.S. Dollars and makes interest payments in Euros based on a notional amount and fixed interest rates determined at contract inception. The effect of net investment hedges on accumulated other comprehensive income and the condensed consolidated statements of operations for the three months ended March 31, 2020 and 2019 was as follows (in thousands): Amount of gain or (loss) recognized in accumulated other comprehensive income: Three Months Ended 2020 2019 Foreign currency debt $ 99,102 $ 63,914 Cross-currency interest rate swaps (included component) (1) 14,140 15,515 Cross-currency interest rate swaps (excluded component) (2) 31,704 (2,590 ) Total $ 144,946 $ 76,839 Amount of gain or (loss) recognized in earnings: Location of gain or (loss) Three Months Ended 2020 2019 Cross-currency interest rate swaps (excluded component) (2) Interest expense $ 5,089 $ 4,163 Total $ 5,089 $ 4,163 (1) Included component represents foreign exchange spot rates. (2) Excluded component represents cross-currency basis spread and interest rates. Cash Flow Hedges . The Company hedges its foreign currency translation exposure for forecasted revenues and expenses in its EMEA region between the U.S. Dollar and the British Pound, Euro, Swedish Krona and Swiss Franc. The foreign currency forward and option contracts that the Company uses to hedge this exposure are designated as cash flow hedges. As of March 31, 2020 and December 31, 2019 , the total notional amounts of these foreign exchange contracts were $985.7 million and $824.8 million , respectively. As of March 31, 2020, the Company's foreign exchange contracts had maturity dates ranging from April 2020 to March 2022 and the Company recorded a net gain of $33.0 million within accumulated other comprehensive income (loss) relating to cash flow hedges that will be reclassified to revenues and expenses as they mature in the next 12 months. As of December 31, 2019, the Company's foreign exchange contracts had maturity dates ranging from January 2020 to December 2021 and the Company recorded a net gain of $16.3 million within accumulated other comprehensive income (loss) relating to cash flow hedges that will be reclassified to revenues and expenses as they mature in the next 12 months. The Company hedges the interest rate exposure created by anticipated fixed rate debt issuances through the use of treasury locks and forward starting swaps (collectively, interest rate locks), which are designated as cash flow hedges. As of March 31, 2020 , the total notional amount of interest rate locks was approximately $1.2 billion . As of December 31, 2019, the Company had no interest rate cash flow hedges outstanding. When interest rate locks are settled, any accumulated gain or loss included as a component of other comprehensive income (loss) will be amortized to interest expense over the life of the related debt. As of March 31, 2020 and December 31, 2019 , the net loss and gain in accumulated other comprehensive income (loss) to be reclassified to interest expense in the next 12 months for interest rate locks is not significant. The Company enters into intercompany hedging instruments ("intercompany derivatives") with wholly-owned subsidiaries of the Company in order to hedge certain forecasted revenues and expenses denominated in currencies other than the U.S. Dollar. Simultaneously, the Company enters into derivative contracts with unrelated third parties to externally hedge the net exposure created by such intercompany derivatives. The effect of cash flow hedges on accumulated other comprehensive income and the condensed consolidated statements of operations for the three months ended March 31, 2020 and 2019 was as follows (in thousands): Amount of gain or (loss) recognized in accumulated other comprehensive income: Three Months Ended 2020 2019 Foreign currency forward and option contracts (included component) (1) $ 28,025 $ 10,965 Foreign currency option contracts (excluded component) (2) 1,318 — Interest rate locks (26,232 ) — Total $ 3,111 $ 10,965 Amount of gain or (loss) reclassified from accumulated other comprehensive income to income: Three Months Ended Location of gain or (loss) 2020 2019 Foreign currency forward contracts Revenues $ 21,219 $ 9,861 Foreign currency forward contracts Costs and operating expenses (11,000 ) (5,329 ) Interest rate locks Interest Expense 168 — Total $ 10,387 $ 4,532 Amount of gain or (loss) excluded from effectiveness testing included in income: Three Months Ended Location of gain or (loss) 2020 2019 Foreign currency forward contracts Other income (expense) $ — $ 88 Foreign currency option contracts (excluded component) (2) Revenues (521 ) — Total $ (521 ) $ 88 (1) Included component represents foreign exchange spot rates. (2) Excluded component represents option's time value. Derivatives Not Designated as Hedging Instruments Embedded Derivatives . The Company is deemed to have foreign currency forward contracts embedded in certain of the Company's customer agreements that are priced in currencies different from the functional or local currencies of the parties involved. These embedded derivatives are separated from their host contracts and carried on the Company's balance sheet at their fair value. The majority of these embedded derivatives arise as a result of the Company's foreign subsidiaries pricing their customer contracts in U.S. Dollars. Economic Hedges of Embedded Derivatives . The Company uses foreign currency forward contracts to manage the foreign exchange risk associated with the Company's customer agreements that are priced in currencies different from the functional or local currencies of the parties involved ("economic hedges of embedded derivatives"). Foreign currency forward contracts represent agreements to exchange the currency of one country for the currency of another country at an agreed-upon price on an agreed-upon settlement date. Foreign Currency Forward Contracts . The Company also uses foreign currency forward contracts to manage the foreign exchange risk associated with certain foreign currency-denominated monetary assets and liabilities. As a result of foreign currency fluctuations, the U.S. Dollar equivalent values of its foreign currency-denominated monetary assets and liabilities change. Gains and losses on these contracts are included in other income (expense), on a net basis, along with the foreign currency gains and losses of the related foreign currency-denominated monetary assets and liabilities associated with these foreign currency forward contracts. As of March 31, 2020 and December 31, 2019 , the total notional amounts of these foreign currency contracts were $4.2 billion and $2.5 billion , respectively.

(2) As presented in the Company's condensed consolidated balance sheets within other current liabilities and other liabilities. Offsetting Derivative Assets and Liabilities The Company presents its derivative instruments and the accrued interest related to cross-currency interest rate swaps at gross fair values in the condensed consolidated balance sheets. The Company enters into master netting agreements with its counterparties for transactions other than embedded derivatives to mitigate credit risk exposure to any single counterparty. Master netting agreements allow for individual derivative contracts with a single counterparty to offset in the event of default. For presentation on the condensed consolidated balance sheets, the Company does not offset fair value amounts recognized for derivative instruments or the accrued interest related to cross-currency interest rate swaps under master netting arrangements. The following table presents information related to these offsetting arrangements as of March 31, 2020 and December 31, 2019 (in thousands): Gross Amounts Offset in Consolidated Balance Sheet Gross Amounts Gross Amounts Offset in the Balance Sheet Net Amounts Gross Amounts not Offset in the Balance Sheet Net March 31, 2020 Derivative assets $ 224,453 $ — $ 224,453 $ (85,190 ) $ 139,263 Derivative liabilities 88,477 — 88,477 (85,190 ) 3,287 December 31, 2019 Derivative assets $ 76,640 $ — $ 76,640 $ (37,820 ) $ 38,820 Derivative liabilities 45,832 — 45,832 (37,820 ) 8,012

Fair Value Measurements

Fair Value Measurements	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Valuation Methods Fair value estimates are made as of a specific point in time based on methods using the market approach valuation method which uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities or other valuation techniques. These techniques involve uncertainties and are affected by the assumptions used and the judgments made regarding risk characteristics of various financial instruments, discount rates, estimates of future cash flows, future expected loss experience and other factors. Cash Equivalents and Investments. The fair value of the Company's investments in money market funds approximates their face value. Such instruments are included in cash equivalents. The Company's money market funds and publicly traded equity securities are classified within Level 1 of the fair value hierarchy because they are valued using quoted prices for identical instruments in active markets. The fair value of the Company's other investments, including certificates of deposit, approximates their face value. The fair value of these investments is priced based on the quoted market price for similar instruments or nonbinding market prices that are corroborated by observable market data. Such instruments are classified within Level 2 of the fair value hierarchy. The Company determines the fair values of its Level 2 investments by using inputs such as actual trade data, benchmark yields, broker/dealer quotes and other similar data, which are obtained from quoted market prices, custody bank, third-party pricing vendors or other sources. The Company uses such pricing data as the primary input to make its assessments and determinations as to the ultimate valuation of its investment portfolio and has not made, during the periods presented, any material adjustments to such inputs. The Company is responsible for its consolidated financial statements and underlying estimates. The Company uses the specific identification method in computing realized gains and losses. Realized gains and losses from the sale of investments are included within other income (expense) in the Company's consolidated statements of operations. The Company's investments in publicly traded equity securities are carried at fair value. Unrealized gains and losses on publicly traded equity securities are reported within other income (expense) in the Company's consolidated statements of operations. Derivative Assets and Liabilities . Inputs used for valuations of derivatives are based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant inputs are observable in the market or can be corroborated by observable market data. The significant inputs used include spot currency rates and forward points, interest rate curves, and published credit default swap rates of its foreign exchange trading counterparties and other comparable companies. The Company has determined that the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, therefore the derivatives are categorized as Level 2. The Company did not have any nonfinancial assets or liabilities measured at fair value on a recurring basis as of March 31, 2020 and December 31, 2019 . The Company's financial assets and liabilities measured at fair value on a recurring basis as of March 31, 2020 were as follows (in thousands): Fair Value at Fair Value Measurement Using Level 1 Level 2 Assets: Money market and deposit accounts $ 453,349 $ 453,349 $ — Publicly traded equity securities 2,664 2,664 — Certificates of deposit 23,169 — 23,169 Derivative instruments (1) 212,191 — 212,191 Total $ 691,373 $ 456,013 $ 235,360 Liabilities: Derivative instruments (1) $ 82,190 $ — $ 82,190 (1) Amounts are included within other current assets, other assets, others current liabilities and other liabilities in the Company's accompanying condensed consolidated balance sheet.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Purchase Commitments As a result of the Company's various IBX data center expansion projects, as of March 31, 2020 , the Company was contractually committed for approximately $0.9 billion of unaccrued capital expenditures, primarily for IBX infrastructure equipment not yet delivered and labor not yet provided, in connection with the work necessary to open these IBX data centers and make them available to customers for installation. The Company also had numerous other, non-capital purchase commitments in place as of March 31, 2020 , such as commitments to purchase power in select locations through the remainder of 2020 and thereafter, and other open purchase orders for goods or services to be delivered or provided during the remainder of 2020 and thereafter. Such other miscellaneous purchase commitments totaled approximately $1.1 billion as of March 31, 2020 . In addition, the Company entered into lease agreements in various locations that have not yet commenced as of March 31, 2020 . For further information on lease commitments, see Note 8 above. Equity Contribution Commitments In connection with the EMEA Joint Venture closed in October 2019, the Company agreed to make future equity contributions to the EMEA Joint Venture. As of March 31, 2020 , the Company had future equity contribution commitments of €16.1 million and £13.1 million , or $33.9 million in total at the exchange rate in effect on March 31, 2020 . Contingent Liabilities The Company estimates exposure on certain liabilities, such as indirect and property taxes, based on the best information available at the time of determination. With respect to real and personal property taxes, the Company records what it can reasonably estimate based on prior payment history, assessed value by the assessor's office, current landlord estimates or estimates based on current or changing fixed asset values in each specific municipality, as applicable. However, there are circumstances beyond the Company's control whereby the underlying value of the property or basis for which the tax is calculated on the property may change, such as a landlord selling the underlying property of one of the Company's IBX data center leases or a municipality changing the assessment value in a jurisdiction and, as a result, the Company's property tax obligations may vary from period to period. Based upon the most current facts and circumstances, the Company makes the necessary property tax accruals for each of its reporting periods. However, revisions in the Company's estimates of the potential or actual liability could materially impact the financial position, results of operations or cash flows of the Company. The Company's indirect and property tax filings in various jurisdictions are subject to examination by local tax authorities. Although we believe that we have adequately assessed and accounted for our potential tax liabilities, and that our tax estimates are reasonable, there can be no certainty that additional taxes will not be due upon audit of our tax returns or as a result of further changes to the tax laws and interpretations thereof. For example, we are currently undergoing audits and appealing the tentative assessments in a number of jurisdictions where we operate, such as France and Brazil. The final results of these audits and the outcomes of the appeals are uncertain and may not be resolved in our favor. The Company regularly assesses the likelihood of adverse outcomes resulting from these examinations and appeals that would affect the adequacy of its tax accruals for each of the reporting periods. If any issues arising from the tax examinations and appeals are resolved in a manner inconsistent with the Company's expectations, the revision of the estimates of the potential or actual liabilities could materially impact the financial position, results of operations, or cash flows of the Company.

(2) The Company has a defined benefit pension plan covering all employees in one country where such plan is mandated by law. The Company does not have any defined benefit plans in any other countries. The unamortized gain (loss) on defined benefit plans includes gains or losses resulting from a change in the value of either the projected benefit obligation or the plan assets resulting from a change in an actuarial assumption, net of amortization. Changes in foreign currencies can have a significant impact to the Company's consolidated balance sheets (as evidenced above in the Company's foreign currency translation loss), as well as its consolidated results of operations, as amounts in foreign currencies are generally translated into more U.S. Dollars when the U.S. Dollar weakens or fewer U.S. Dollars when the U.S. Dollar strengthens. As of March 31, 2020 , the U.S. Dollar was generally stronger relative to certain of the currencies of the foreign countries in which the Company operates as compared to December 31, 2019. This overall strengthening of the U.S. Dollar had an overall unfavorable impact on the Company's condensed consolidated financial position because the foreign denominations translated into fewer U.S. Dollars as evidenced by an increase in foreign currency translation loss for the three months ended March 31, 2020 as reflected in the above table. The volatility of the U.S. Dollar as compared to the other currencies in which the Company operates could have a significant impact on its condensed consolidated financial position and results of operations including the amount of revenue that the Company reports in future periods. Common Stock In March 2019, the Company issued and sold 2,985,575 shares of common stock in a public offering pursuant to a registration statement and a related prospectus and prospectus supplement. The Company received net proceeds of approximately $1,213.4 million , net of underwriting discounts, commissions and offering expenses. In December 2018, the Company launched an ATM program, under which it may offer and sell from time to time up to an aggregate of $750.0 million of its common stock in "at the market" transactions (the "ATM Program"). For the three months ended March 31, 2020 , the Company sold 162,530 shares under the ATM Program, for approximately $101.8 million , net of payment of commissions to sales agents and other offering expenses. During the quarter ended March 31, 2019, no sales were made under the ATM Program. Stock-Based Compensation For the three months ended March 31, 2020 , the Compensation Committee and/or the Stock Award Committee of the Company's Board of Directors, as the case may be, approved the issuance of an aggregate of 653,281 shares of restricted stock units to certain employees, including executive officers, pursuant to the 2000 Equity Incentive Plan. These equity awards are subject to vesting provisions and have a weighted-average grant date fair value of $579.24 and a weighted-average requisite service period of 3.31 years. The valuation of restricted stock units with only a service condition or a service and performance condition requires no significant assumptions as the fair value for these types of equity awards is based solely on the fair value of the Company's stock price on the date of grant. The Company used revenues and adjusted funds from operations ("AFFO") per share as the performance measurements in the restricted stock units with both service and performance conditions that were granted in the three months ended March 31, 2020 . The Company uses a Monte Carlo simulation option-pricing model to determine the fair value of restricted stock units with a service and market condition. The Company used total shareholder return ("TSR") as the performance measurement in the restricted stock units with a service and market condition that were granted in the three months ended March 31, 2020 . There were no significant changes in the assumptions used to determine the fair value of restricted stock units with a service and market condition that were granted in 2020 compared to the prior year. The following table presents, by operating expense category, the Company's stock-based compensation expense recognized in the Company's condensed consolidated statements of operations (in thousands): Three Months Ended 2020 2019 Cost of revenues $ 9,343 $ 5,012 Sales and marketing 18,545 13,301 General and administrative 52,678 30,710 Total $ 80,566 $ 49,023

On April 18, 2020, the Company entered into an agreement to form a second joint venture in the form of a limited liability partnership with GIC to develop and operate xScale data centers in Asia-Pacific (the “Asia-Pacific Joint Venture”). Upon closing, GIC will contribute cash in exchange for an 80% partnership interest in the Asia-Pacific Joint Venture. The Company will contribute three development sites in Japan to the Asia-Pacific Joint Venture in exchange for a 20% partnership interest in the Asia-Pacific Joint Venture and cash proceeds. The completion of the Asia-Pacific Joint Venture is subject to closing conditions.

Basis of Presentation and Sig_2

Basis of Presentation and Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2020
Accounting Policies [Abstract]
Basis of Presentation	The accompanying unaudited condensed consolidated financial statements have been prepared by Equinix, Inc. ("Equinix" or the "Company") and reflect all adjustments, consisting only of normal recurring adjustments, which in the opinion of management are necessary to fairly state the financial position and the results of operations for the interim periods presented. The condensed consolidated balance sheet data as of December 31, 2019 has been derived from audited consolidated financial statements as of that date. The condensed consolidated financial statements have been prepared in accordance with the regulations of the Securities and Exchange Commission ("SEC"), but omit certain information and footnote disclosure necessary to present the statements in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP"). For further information, refer to the Consolidated Financial Statements and Notes thereto included in Equinix's Form 10-K as filed with the SEC on February 21, 2020. Results for the interim periods are not necessarily indicative of results for the entire fiscal year.
Consolidation	The accompanying unaudited condensed consolidated financial statements include the accounts of Equinix and its subsidiaries, including the acquisitions of Packet Host, Inc. from March 2, 2020, three data centers in Mexico acquired from Axtel S.A.B. de C.V from January 8, 2020, and Switch Datacenters' AMS1 data center business in Amsterdam, Netherlands from April 18, 2019. All intercompany accounts and transactions have been eliminated in consolidation.
Income Taxes	The Company elected to be taxed as a real estate investment trust for U.S. federal income tax purposes ("REIT") beginning with its 2015 taxable year. As a result, the Company may deduct the distributions made to its stockholders from taxable income generated by the Company and its qualified REIT subsidiaries ("QRSs"). The Company's dividends paid deduction generally eliminates the U.S. federal taxable income of the Company and its QRSs, resulting in no U.S. federal income tax due. However, the Company's domestic taxable REIT subsidiaries ("TRSs") are subject to U.S. corporate income taxes on any taxable income generated by them. In addition, the foreign operations of the Company are subject to local income taxes regardless of whether the foreign operations are operated as QRSs or TRSs. The Company provides for income taxes during interim periods based on the estimated effective tax rate for the year. The effective tax rate is subject to change in the future due to various factors such as the operating performance of the Company, tax law changes and future business acquisitions.
Recent Accounting Pronouncements	Accounting Standards Not Yet Adopted In December 2019, Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2019-12, Income Taxes ("Topic 740"): Simplifying the Accounting for Income T axes. The ASU simplifies accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The ASU also improves consistent application of and simplifies generally accepted accounting principles ("GAAP") for other areas of Topic 740 by clarifying and amending existing guidance. For public entities, the ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted including adoption in any interim period for periods for which financial statements have not yet been issued. The Company is currently evaluating the extent of the impact that the adoption of this standard will have on its condensed consolidated financial statements. Accounting Standards Adopted In March 2020, FASB issued ASU 2020-04, Reference Rate Reform ("Topic 848"): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The ASU provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The ASU is effective for all entities as of March 12, 2020 through December 31, 2022. The Company adopted the ASU upon its issuance and there was no impact on the Company's condensed consolidated financial statements for the three months ended March 31, 2020 as a result of adopting this standard. The Company will evaluate its debt, derivative and lease contracts that are eligible for modification relief and may apply the elections prospectively as needed. In June 2016, FASB issued ASU 2016-13, Financial Instruments - Credit Losses ("Topic 326"): Measurement of Credit Losses on Financial Instruments. The ASU requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. The ASU requires enhanced qualitative and quantitative disclosures to help investors and other financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization's portfolio. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted. The Company adopted this new ASU on January 1, 2020 using the modified retrospective approach and recorded a net decrease to retained earnings of $ 0.9 million and a corresponding increase to allowance for doubtful accounts. The adoption did not have any significant impact on other financial assets within the scope of ASC 326, such as contract asset.
Accounts Receivable	Accounts receivables are recorded at invoice amount and are generally due in less than one year. Allowance for doubtful accounts are estimated losses resulting from the inability of customers making payments. An estimate of uncollectible amounts is made based on historical bad debts, age of customer receivable balances, customers' financial conditions and current economic trends.

Derivatives Designated as Hedging Instruments	Cash Flow Hedges . Derivatives Designated as Hedging Instruments Net Investment Hedges. The Company is exposed to the impact of foreign exchange rate fluctuations on the value of investments in its foreign subsidiaries whose functional currencies are other than the U.S. Dollar. In order to mitigate the impact of foreign currency exchange rates, the Company has entered into various foreign currency debt obligations, which are designated as hedges against the Company's net investments in foreign subsidiaries. As of March 31, 2020 and December 31, 2019 , the total principal amounts of foreign currency debt obligations designated as net investment hedges were $4,245.1 million and $4,078.7 million , respectively. The Company also uses cross-currency interest rate swaps to hedge a portion of its net investment in its European operations. As of both March 31, 2020 and December 31, 2019 , U.S. Dollar to Euro cross-currency interest rate swap contracts with a total notional amount of $750.0 million were outstanding, with maturity dates in April 2022, January 2024 and January 2025. At maturity of each outstanding contract, the Company will receive U.S. Dollars from and pay Euros to the contract counterparty. During the term of each contract, the Company receives interest payments in U.S. Dollars and makes interest payments in Euros based on a notional amount and fixed interest rates determined at contract inception.
Derivatives Not Designated as Hedging Instruments	Derivatives Not Designated as Hedging Instruments Embedded Derivatives . The Company is deemed to have foreign currency forward contracts embedded in certain of the Company's customer agreements that are priced in currencies different from the functional or local currencies of the parties involved. These embedded derivatives are separated from their host contracts and carried on the Company's balance sheet at their fair value. The majority of these embedded derivatives arise as a result of the Company's foreign subsidiaries pricing their customer contracts in U.S. Dollars. Economic Hedges of Embedded Derivatives . The Company uses foreign currency forward contracts to manage the foreign exchange risk associated with the Company's customer agreements that are priced in currencies different from the functional or local currencies of the parties involved ("economic hedges of embedded derivatives"). Foreign currency forward contracts represent agreements to exchange the currency of one country for the currency of another country at an agreed-upon price on an agreed-upon settlement date. Foreign Currency Forward Contracts .
Fair Value Measurements	Valuation Methods Fair value estimates are made as of a specific point in time based on methods using the market approach valuation method which uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities or other valuation techniques. These techniques involve uncertainties and are affected by the assumptions used and the judgments made regarding risk characteristics of various financial instruments, discount rates, estimates of future cash flows, future expected loss experience and other factors. Cash Equivalents and Investments. The fair value of the Company's investments in money market funds approximates their face value. Such instruments are included in cash equivalents. The Company's money market funds and publicly traded equity securities are classified within Level 1 of the fair value hierarchy because they are valued using quoted prices for identical instruments in active markets. The fair value of the Company's other investments, including certificates of deposit, approximates their face value. The fair value of these investments is priced based on the quoted market price for similar instruments or nonbinding market prices that are corroborated by observable market data. Such instruments are classified within Level 2 of the fair value hierarchy. The Company determines the fair values of its Level 2 investments by using inputs such as actual trade data, benchmark yields, broker/dealer quotes and other similar data, which are obtained from quoted market prices, custody bank, third-party pricing vendors or other sources. The Company uses such pricing data as the primary input to make its assessments and determinations as to the ultimate valuation of its investment portfolio and has not made, during the periods presented, any material adjustments to such inputs. The Company is responsible for its consolidated financial statements and underlying estimates. The Company uses the specific identification method in computing realized gains and losses. Realized gains and losses from the sale of investments are included within other income (expense) in the Company's consolidated statements of operations. The Company's investments in publicly traded equity securities are carried at fair value. Unrealized gains and losses on publicly traded equity securities are reported within other income (expense) in the Company's consolidated statements of operations. Derivative Assets and Liabilities . Inputs used for valuations of derivatives are based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant inputs are observable in the market or can be corroborated by observable market data. The significant inputs used include spot currency rates and forward points, interest rate curves, and published credit default swap rates of its foreign exchange trading counterparties and other comparable companies. The Company has determined that the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, therefore the derivatives are categorized as Level 2.
