Accounting Policies [Abstract]
Basis of Presentation	The accompanying unaudited condensed consolidated financial statements have been prepared by Equinix, Inc. (collectively with its consolidated subsidiaries referred to as "Equinix," the "Company," "we," "our," or "us") 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. Our condensed consolidated balance sheet data as of December 31, 2024 has been derived from audited consolidated financial statements as of that date. Our 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" or "GAAP"). For further information, refer to the Consolidated Financial Statements and Notes thereto included in our Form 10-K as filed with the SEC on February 12, 2025. Results for the interim periods are not necessarily indicative of results for the entire fiscal year.
Consolidation	All intercompany accounts and transactions have been eliminated in consolidation.
Income Taxes	Income Taxes We elected to be taxed as a real estate investment trust for U.S. federal income tax purposes ("REIT") beginning with our 2015 taxable year. As a result, we may deduct the dividends paid to our stockholders from taxable income generated by our REIT and qualified REIT subsidiaries ("QRSs"). Our dividends paid deduction generally eliminates the U.S. federal taxable income of our REIT and QRSs, resulting in no U.S. federal income tax due. However, our domestic taxable REIT subsidiaries ("TRSs") are subject to U.S. corporate income taxes on any taxable income generated by them. In addition, our foreign operations are subject to local income taxes regardless of whether the foreign operations are operated as QRSs or TRSs. We accrue 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 our operating performance, tax law changes and future business acquisitions.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Accounting Standards Not Yet Adopted In November 2024, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2024-03: Disaggregation of Income Statement Expenses ("DISE"). The ASU requires additional disclosure of the nature of expenses included in the income statement. The ASU is effective for annual reporting periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027. The requirements will be applied prospectively with the option for retrospective application. Early adoption is permitted. We are currently evaluating the extent of the impact of this ASU on disclosures in our condensed consolidated financial statements. In December 2023, FASB issued ASU 2023-09, Income Taxes ("Topic 740"): Improvements to Income Tax Disclosures. This ASU is intended to enhance the transparency and decision usefulness of income tax disclosures by requiring (i) consistent categories and greater disaggregation of information in the rate reconciliation and (ii) income taxes paid disaggregated by jurisdiction. The ASU is effective for annual reporting periods beginning after December 15, 2024 and should be applied prospectively, with retrospective application and early adoption both permitted. We are currently evaluating the extent of the impact of this ASU on disclosures in our condensed consolidated financial statements. Accounting Standards Adopted Segment Reporting In November 2023, FASB issued ASU 2023-07, Segment Reporting ("Topic 280"): Improvements to Reportable Segment Disclosure. The ASU is intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The ASU is effective for annual reporting periods beginning after December 15, 2023, and interim reporting periods within fiscal years beginning after December 15, 2024, with early adoption permitted and retrospective adoption required. We adopted this ASU for the 2024 annual reporting period and the 2025 interim reporting periods. Refer to Note 13 for disclosures required by this ASU.
Remaining performance obligations	Remaining performance obligations As of March 31, 2025, approximately $11.3 billion of total revenues, including deferred installation revenues, are expected to be recognized in future periods. Most of our revenue contracts have an initial term varying from one to five years, and thereafter, automatically renew in one-year increments. Included in the remaining performance obligations are contracts that are either under the initial term or under one-year renewal periods. We expect to recognize approximately 65% of our remaining performance obligations as revenues over the next two years, with more revenues expected to be recognized in the first year due to the impact of contract renewals. The remainder of the balance is generally expected to be recognized over the next three to five years. We estimate our remaining performance obligations at a point in time. Actual amounts and timing of revenue recognition may differ from these estimates due to changes in actual deployment dates, contract modifications, renewals and/or terminations. 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® data centers that are based on future events or actual costs incurred in the future, or any contracts that could be terminated without any significant penalties including the majority of interconnection revenues. The remaining performance obligations above include revenues to be recognized in the future related to arrangements where we are considered the lessor.
Derivatives and Other Instruments Designated as Hedging Instruments	Derivatives and Other Instruments Designated as Hedging Instruments Net Investment Hedges Foreign Currency Debt: We are exposed to the impact of foreign exchange rate fluctuations on the value of investments in our foreign subsidiaries whose functional currencies are other than the U.S. dollar. In order to mitigate the impact of foreign currency exchange rates, we have entered into various foreign currency debt obligations, which are designated as hedges against our net investments in foreign subsidiaries. As of March 31, 2025 and December 31, 2024, the total principal amounts of foreign currency debt obligations designated as net investment hedges were $1.1 billion and $1.0 billion, respectively. Foreign Currency Forward Contracts: We use foreign currency forward contracts, designated as net investment hedges, to hedge against the effect of foreign exchange rate fluctuations on our net investment in our foreign subsidiaries. We use the spot method to assess hedge effectiveness and recognize fair value changes from spot rates in other comprehensive income (loss). We exclude forward points from the assessment of hedge effectiveness and amortize the initial value of the excluded component through interest expense. The difference between fair value changes from the excluded component and the amount amortized is recognized in other comprehensive income (loss). Embedded Derivatives: Certain of our customer agreements that are priced in currencies different from the functional or local currencies of the parties involved are deemed to have foreign currency forward contracts embedded in them. These embedded derivatives are separated from their host contracts and carried on our balance sheet at their fair value. The majority of these embedded derivatives arise as a result of our foreign subsidiaries pricing their customer contracts in U.S. dollars. We use these forward contracts embedded within our customer agreements to hedge against the effect of foreign exchange rate fluctuations on our net investment in our foreign subsidiaries. As of both March 31, 2025 and December 31, 2024, the total remaining contract value of such customer agreements outstanding under this hedging program was $191 million and $213 million, respectively. Cross-currency Interest Rate Swaps: We also use cross-currency interest rate swaps, designated as net investment hedges, which effectively convert a portion of our U.S. dollar-denominated fixed-rate debt to foreign currency-denominated fixed-rate debt, to hedge the currency exposure associated with our net investment in our foreign subsidiaries. We use the spot method to assess hedge effectiveness and recognize fair value changes from spot rates in other comprehensive income (loss). Cash Flow Hedges Foreign Currency Forward Contracts: We enter into intercompany foreign currency forward contracts ("intercompany derivatives") with our wholly-owned subsidiaries in our EMEA region in order to hedge certain forecasted revenues and expenses denominated in currencies other than the U.S. Dollar (primarily the British Pound and the Euro). Simultaneously, we enter into foreign currency forward contracts with unrelated third parties to externally hedge the net exposure created by such intercompany derivatives. We designate the intercompany derivatives as cash flow hedges. We do not exclude any components from the assessment of hedge effectiveness and the change in fair value of these derivatives is recognized in other comprehensive income (loss) until the hedged transaction occurs.
Fair Value Measurements	We perform fair value measurements in accordance with ASC 820, Fair Value Measurement, which establishes three levels of inputs that we use to measure fair value: •Level 1: quoted prices in active markets for identical assets or liabilities. •Level 2: observable inputs (e.g., spot rates and other data from the third-party pricing vendors for our derivative instruments, credit rating and current prices of similar debt instruments that are publicly traded for our debt instruments) other than quoted market prices included within Level 1 that are observable, either directly or indirectly, for the assets or liabilities. •Level 3: unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of assets or liabilities, including indicative pricing from third parties for similar instruments and asset-specific yield adjustments for elements such as credit risk.

Fair Value Measurements

We perform fair value measurements in accordance with ASC 820, Fair Value Measurement, which establishes three levels of inputs that we use to measure fair value:

•Level 1: quoted prices in active markets for identical assets or liabilities.

•Level 2: observable inputs (e.g., spot rates and other data from the third-party pricing vendors for our derivative instruments, credit rating and current prices of similar debt instruments that are publicly traded for our debt instruments) other than quoted market prices included within Level 1 that are observable, either directly or indirectly, for the assets or liabilities.

•Level 3: unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of assets or liabilities, including indicative pricing from third parties for similar instruments and asset-specific yield adjustments for elements such as credit risk.

- Definition

Disclosure of accounting policy for income taxes, which may include its accounting policies for recognizing and measuring deferred tax assets and liabilities and related valuation allowances, recognizing investment tax credits, operating loss carryforwards, tax credit carryforwards, and other carryforwards, methodologies for determining its effective income tax rate and the characterization of interest and penalties in the financial statements.
