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. (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. In the preparation of our condensed consolidated financial statements, we have considered potential impacts of the COVID-19 pandemic on our critical and significant accounting estimates. There was no significant impact to our condensed consolidated financial statements. We will continue to evaluate the nature and extent of the potential impacts to our business and our condensed consolidated financial statements. Our condensed consolidated balance sheet data as of December 31, 2020 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"). 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 19, 2021. 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 our acquisitions of two data centers in Mumbai, India from India operations of GPX Global Systems, Inc. ("GPX India") from September 1, 2021, 12 data center sites across Canada from BCE Inc. ("Bell") from October 1, 2020 and one additional data center site from November 2, 2020, Packet Host, Inc. (“Packet”) from March 2, 2020, and three data centers in Mexico acquired from Axtel S.A.B. de C.V ("Axtel") from January 8, 2020. All intercompany accounts and transactions have been eliminated in consolidation. 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 distributions made 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. Our effective tax rates were 15.2% and 24.7% for the nine months ended September 30, 2021 and 2020, respectively. The decrease in the effective tax rate for the nine months ended September 30, 2021 as compared to the same period in 2020 is primarily due to the favorable resolution of uncertain tax positions of approximately $70.0 million resulting from the settlement of various tax audits in the United Kingdom ("UK"), Germany, and Australia, partially offset by $10.9 million resulting from the revaluation of our deferred tax liabilities due to the UK corporate tax rate increase from 19% to 25% enacted in the current period. Of the unrecognized tax benefits being realized in the nine months ended September 30, 2021, $32.3 million is related to the uncertain tax position inherited from the Metronode acquisition closed in 2018. The uncertain tax position was covered by an indemnification agreement with the Seller. The realization of the unrecognized tax benefits resulted in an impairment of the indemnification asset for the same amount, which has been included in Other Income (Expense) on the Condensed Consolidated Statements of Operations for the nine months ended September 30, 2021. Recent Accounting Pronouncements Accounting Standards Not Yet Adopted In October 2021, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2021-08 Business Combinations ("Topic 805"): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. The ASU requires contract assets and contract liabilities acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with ASC 606, Revenue from Contracts with Customers, as if it had originated the contracts. Under the current business combinations guidance, such assets and liabilities were recognized by the acquirer at fair value on the acquisition date. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022, with early adoption permitted. We are currently evaluating the extent of the impact of this ASU, but do not expect the adoption of this standard to have a significant impact on our condensed consolidated financial statements. In August 2020, FASB issued ASU 2020-06: Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40). The ASU simplifies the accounting for convertible instruments by reducing the number of accounting models for convertible debt instruments and convertible preferred stock and modifies the disclosure requirement for the convertible instruments. Additionally, this ASU improves the consistency of EPS calculations by eliminating the use of the treasury stock method to calculate diluted EPS for convertible instruments and clarifies certain areas under the current EPS guidance. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2021, with early adoption permitted at the beginning of the fiscal year after December 15, 2020. We are currently evaluating the extent of the impact of this ASU, but do not expect the adoption of this standard to have a significant impact on our condensed consolidated financial statements. Accounting Standards Adopted In December 2019, FASB issued 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. 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. On January 1, 2021, we adopted this ASU on a prospective basis and the adoption of this standard did not have an impact on our condensed consolidated financial statements. In March 2020, FASB issued ASU 2020-04, Reference Rate Reform ("Topic 848"): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. In addition, FASB issued ASU 2021-01, Reference Rate Reform ("Topic 848"), which clarifies the scope of Topic 848. Collectively, the guidance 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. ASU 2020-04 was effective for all entities as of March 12, 2020 through December 31, 2022 and ASU 2021-01 is effective upon issuance. We adopted these ASUs upon their respective issuances and there was no impact on our condensed consolidated financial statements as a result of adopting the guidance. We will evaluate our debt, derivative and lease contracts that may become eligible for modification relief and may apply the elections prospectively as needed.

Revenue from Contract with Customer [Abstract]
Revenue	Revenue Contract Balances The following table summarizes the opening and closing balances of our accounts receivable, net; contract assets, current; contract assets, non-current; deferred revenue, current; and deferred revenue, non-current (in thousands): Accounts receivable, net (1) Contract assets, current Contract assets, non-current Deferred revenue, current Deferred revenue, non-current Beginning balances as of January 1, 2021 $ 676,738 $ 13,534 $ 54,050 $ 101,258 $ 71,242 Closing balances as of September 30, 2021 792,101 49,793 51,452 112,952 66,318 Increase (Decrease) $ 115,363 $ 36,259 $ (2,598) $ 11,694 $ (4,924) (1) The net change in our allowance for credit losses was insignificant during the nine months ended September 30, 2021. The difference between the opening and closing balances of our accounts receivable, net, contract assets and deferred revenues primarily results from revenue growth and the timing difference between the satisfaction of our performance obligation and the customer's payment. The amount of revenue recognized during the nine months ended September 30, 2021 from the opening deferred revenue balance as of January 1, 2021 was $72.0 million. Remaining performance obligations As of September 30, 2021, approximately $8.5 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 three 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 70% 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 contracts renewal. 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 deployments 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 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 we are considered the lessor.

In addition, we 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, we 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 Equinix Metal TM , is expected to accelerate our strategy to help enterprises deploy hybrid multicloud architectures on our data center platform. Acquisition of data centers from Axtel (the "Axtel Acquisition") On January 8, 2020, we 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 we 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 our ongoing expansion to meet customer demand in our Americas region. Purchase Price Allocation Each of these 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 this method, the total purchase price is allocated to the assets acquired and liabilities assumed measured at fair value on the date of acquisition. As of September 30, 2021, we had not completed the detailed valuation analysis to derive the fair value of assets acquired and liabilities assumed from the GPX India Acquisition, 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 allocation of total purchase consideration is presented as follows (in thousands): GPX India Bell Packet Axtel Provisional Final Cash and cash equivalents $ 9,406 $ — $ 1,068 $ — Accounts receivable 4,399 — 5,098 — Other current assets 8,771 696 299 14,048 Property, plant and equipment 88,108 538,717 27,945 76,407 Operating lease right-of-use assets 62 14,359 1,519 1,646 Intangible assets 15,472 75,857 58,500 22,750 Goodwill 77,296 172,387 230,620 78,902 Deferred tax and other assets 20 722 138 — Total assets acquired 203,534 802,738 325,187 193,753 Accounts payable and accrued liabilities (1,591) (895) (1,275) (238) Other current liabilities (478) — (860) — Operating lease liabilities (62) (13,340) (1,519) (1,586) Finance lease liabilities (20,565) (80,026) (27,945) — Deferred tax and other liabilities (10,373) (4,495) (3,290) (2,911) Net assets acquired $ 170,465 $ 703,982 $ 290,298 $ 189,018 Property, plant and equipment - The fair values of property, plant and equipment acquired from these four acquisitions were estimated by applying the cost approach, with the exception of land, which we 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. Intangible assets - 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) GPX India: Customer relationships $ 15,472 15.0 15.0 Bell: Customer relationships 75,857 15.0 15.0 Packet: Trade names 1,300 3.0 3.0 Existing technology 5,100 3.0 3.0 Customer relationships 52,100 10.0 10.0 Axtel: Customer relationships 22,750 15.0 15.0 The fair values of customer relationships acquired from these acquisitions were estimated from 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. We applied a discount rate of 11.0% for GPX India, 8.0% for Bell, 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 the Packet trade name was estimated using the relief from royalty method under the income approach. We 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. Goodwill 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 these acquisitions. Goodwill from the Bell, Packet, and Axtel acquisitions is attributable to our Americas region and goodwill from the GPX India Acquisition is attributable to the Asia-Pacific region. Goodwill from the Bell Acquisition is expected to be deductible for local tax purposes while goodwill from the GPX India, Packet and Axtel Acquisitions are not deductible for local tax purposes. Revenues and net income and loss from operations The operating results of the GPX India Acquisition are reported in the Asia-Pacific region following the date of acquisition. During the three and nine months ended September 30, 2021, our results of operations from the GPX India Acquisition were insignificant. Transaction costs During the nine months ended September 30, 2021, the transaction costs for the GPX India Acquisition were insignificant.

Assets Held for Sale	Assets Held for Sale In October 2021, we entered into an agreement to form a joint venture in the form of a limited liability partnership with PGIM Real Estate ("PGIM"), to develop and operate xScale TM data centers in Asia-Pacific (the "Asia-Pacific 2 Joint Venture"). 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 our comprehensive suite of interconnection and edge services. Upon closing, PGIM will contribute cash in exchange for an 80% partnership interest in the Asia-Pacific 2 Joint Venture. We agreed to sell the Sydney 9 ("SY9") data center site in exchange for a 20% partnership interest in the Asia-Pacific 2 Joint Venture and cash proceeds. The assets and liabilities of the SY9 data center, which are currently included within our Asia-Pacific region, were classified as held for sale as of September 30, 2021. In June 2021, we entered into an agreement to form another joint venture in the form of a limited liability partnership with GIC, Singapore's sovereign wealth fund ("GIC"), to develop and operate additional xScale data centers in Europe and the Americas (the “EMEA 2 Joint Venture”). The assets and liabilities of the data center sites expected to be sold to the EMEA 2 Joint Venture within a year were classified as held for sale as of June 30, 2021. The transaction is structured to close in phases over the course of two years, pending regulatory approval and other closing conditions. The first phase of the transaction, comprised of data center sites located in Frankfurt, Helsinki, Madrid, Milan and Paris, closed in September 2021. Upon closing, we sold these data center sites in exchange for a total consideration of $144.0 million, which is comprised of $106.4 million of net cash proceeds, a 20% partnership interest in the EMEA 2 Joint Venture with a fair value of $30.4 million, and $7.2 million of receivables. During the three months ended September 30, 2021, we recognized an insignificant gain on the sale of the xScale data center facilities. The assets and liabilities of Warsaw 4 ("WA4") and Sao Paulo 5 ("SP5") data center sites, which are currently included within our EMEA and Americas regions respectively, were expected to be sold to the EMEA 2 Joint Venture in the next phases and remained classified as held for sale as of September 30, 2021. The sale of the SP5 data center closed in October 2021 (see Note 14 below). Additionally, we entered negotiations to sell the Mexico 3 ("MX3") data center site in connection with the formation of a new joint venture with GIC. Given that the key terms of the sale had been substantially agreed upon as of September 30, 2021, the assets and liabilities of the MX3 data center, which are currently included within our Americas region, were classified as held for sale as of September 30, 2021. In May 2021, we entered into an agreement to sell the Dublin 5 ("DB5") data center site to the EMEA 1 Joint Venture (as defined in note 6 below). The assets and liabilities of the DB5 data center, which were included within our EMEA region, were classified as held for sale as of June 30, 2021. In July 2021, we sold the DB5 data center in exchange for a total consideration of $77.9 million. During the three months ended September 30, 2021, we recognized a total gain of $15.8 million on the sale of the DB5 data center. All assets and liabilities classified as held for sale are reported at the lower of their carrying amounts or fair values less costs to sell. The following table summarizes the assets and liabilities that were classified as assets and liabilities held for sale in the condensed consolidated balance sheet as of September 30, 2021 (in thousands): September 30, Operating lease right-of-use assets $ 10,990 Property, plant and equipment 223,318 Other assets 1,022 Total assets held for sale $ 235,330 Accrued property, plant and equipment $ 24,085 Total liabilities held for sale (1) $ 24,085 (1) Liabilities held for sale were included within other current liabilities on the condensed consolidated balance sheet.

The EMEA 1 Joint Venture is not a variable interest entity ("VIE") given that both equity investors' interests have the characteristics of a controlling financial interest and it is sufficiently capitalized to sustain its operations, requiring additional funding from its partners only when expanding operations. Our share of income and losses of equity method investments from this joint venture was insignificant for the three and nine months ended September 30, 2021 and 2020 and was included in other income (expense) on the condensed consolidated statement of operations. We committed to make future equity contributions to the EMEA 1 Joint Venture for funding its future development. As of September 30, 2021, we had future equity contribution commitments of $43.6 million. VIE Joint Ventures Asia-Pacific 1 and EMEA 2 Joint Ventures In 2020, we entered into a second joint venture in the form of a limited liability partnership with GIC (the "Asia-Pacific 1 Joint Venture") to develop and operate xScale data centers in Asia-Pacific. In 2021, we entered into another joint venture in the form of a limited liability partnership with GIC (the "EMEA 2 Joint Venture") to develop and operate additional xScale data centers in Europe and the Americas (see Note 5 above). For both the Asia-Pacific 1 Joint Venture and the EMEA 2 Joint Venture, we provide certain management services to their operations and earn fees for the performance of such services. Both joint ventures do not have sufficient funds from operations to be self-sustaining, thus are considered VIEs. The power to direct the activities of these joint ventures that most significantly impact economic performance is shared equally between GIC and us. These activities include data center construction and operations, sales and marketing, financing, and real estate purchases or sales. Decisions about these activities require the consent of both GIC and us. We concluded that neither party is deemed to have predominant control over the Asia-Pacific 1 Joint Venture and EMEA 2 Joint Venture and neither party is considered to be the primary beneficiary. During the three and nine months ended September 30, 2021, our share of income and losses of equity method investments from these joint ventures was insignificant both individually and in aggregate, and was included in other income (expense) on the condensed consolidated statement of operations. The following table summarizes our maximum exposure to loss related to the Asia-Pacific 1 Joint Venture and EMEA 2 Joint Venture as of September 30, 2021 (in thousands): Asia-Pacific 1 Joint Venture EMEA 2 Joint Venture Equity Investment $ 56,566 $ 30,386 Outstanding Receivables 3,844 11,451 Future Equity Contribution Commitments 1 1,098 57,662 Maximum Future Payments under Debt Guarantees 2 N/A 3 30,389 Total $ 61,508 $ 129,888 (1) The joint ventures' partners are required to make additional equity contributions proportionately upon certain occurrences, such as a shortfall in capital necessary to complete certain construction phases or make interest payments on their outstanding debt. (2) In connection with our 20% equity investment in the EMEA 2 Joint Venture, we provided the lenders with our guarantees covering 20% of all payments of principal and interest due under EMEA 2 Joint Venture's credit facility agreements (see Note 11). (3) The Asia-Pacific 1 Joint Venture’s debt is secured by the net assets of the Asia-Pacific 1 Joint Venture without recourse to its partners. Other Related Party Transactions We have lease arrangements and provide various services to the EMEA 1 Joint Venture, Asia-Pacific 1 Joint Venture and EMEA 2 Joint Venture (the "Joint Ventures") through multiple agreements, including sales and marketing, development management, facilities management, and asset management services. These transactions are generally considered to have been negotiated at arm's length.

(2) A portion of the contract asset balance relates to commitments to the EMEA 1 Joint Venture to complete a residual portion of the PA9 data center sold to the EMEA 1 Joint Venture, which is reimbursable in full upon completion. The remaining balance represents contract assets recorded under our commercial service agreements. (3) Balances pertain to the LD10-2 data center sub-lease as described above. (4) We have an agreement to lease to the EMEA 1 Joint Venture a portion of land for the Frankfurt 9 xScale data center and a new building that is under construction on the land. As of September 30, 2021, the lease has not commenced yet. Balance primarily consists of liabilities recorded in connection with the construction of the Frankfurt 9 xScale data center. The remaining balance pertains to meter and power charge accruals under the LD 10-2 sublease. We received contingent consideration from the sales of xScale data centers to the EMEA 1 Joint Venture, which become receivable upon completion of certain performance milestones, primarily contingent on the local regulatory approvals for certain sites. The contingent consideration are considered derivatives and are remeasured at 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. The contingencies were partially met during the nine months ended September 30, 2021 upon achieving the performance milestone for one of the sites. As of September 30, 2021 and December 31, 2020, the total fair value of the remaining contingent consideration was $15.2 million and $44.2 million, respectively, which was included in other current assets on the condensed consolidated balance sheets. Changes in the fair value of the contingent consideration were recorded in gain (loss) on asset sales on the condensed consolidated statement of operations.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	Derivatives and Hedging Activities Derivatives Designated as Hedging Instruments Net Investment Hedges. 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 September 30, 2021 and December 31, 2020, the total principal amounts of foreign currency debt obligations designated as net investment hedges were $1.5 billion and $1.9 billion, respectively. We also use cross-currency interest rate swaps, 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. As of September 30, 2021 and December 31, 2020, we had cross-currency interest rate swaps outstanding with notional amounts of $4.0 billion and $3.3 billion respectively, with maturity dates ranging through 2026. From time to time, we use foreign currency forward contracts to hedge against the effect of foreign exchange rate fluctuations on our net investment in our foreign subsidiaries. As of September 30, 2021 and December 31, 2020, the total notional amount of foreign currency forward contracts designated as net investment hedges were $375.7 million and $355.6 million respectively. The effect of net investment hedges on accumulated other comprehensive income and the condensed consolidated statements of operations for the three and nine months ended September 30, 2021 and 2020 was as follows (in thousands): Amount of gain or (loss) recognized in accumulated other comprehensive income: Three Months Ended Nine Months Ended 2021 2020 2021 2020 Foreign currency debt $ 36,308 $ (130,774) $ 81,290 $ (116,887) Cross-currency interest rate swaps (included component) (1) 89,494 (78,226) 207,598 (74,419) Cross-currency interest rate swaps (excluded component) (2) (2,527) (16,588) (27,944) 13,606 Foreign currency forward contracts (included component) (1) 7,858 (1,485) 3,302 (1,485) Foreign currency forward contracts (excluded component) (3) (53) (28) (27) (28) Total $ 131,080 $ (227,101) $ 264,219 $ (179,213) Amount of gain or (loss) recognized in earnings: Location of gain or (loss) Three Months Ended Nine Months Ended 2021 2020 2021 2020 Cross-currency interest rate swaps (excluded component) (2) Interest expense $ 11,863 $ 6,613 $ 32,478 $ 17,161 Foreign currency forward contracts (excluded component) (3) Interest expense 38 1 242 1 Total $ 11,901 $ 6,614 $ 32,720 $ 17,162 (1) Included component represents foreign exchange spot rates. (2) Excluded component represents cross-currency basis spread and interest rates. (3) Excluded component represents foreign currency forward points. Cash Flow Hedges . We hedge our foreign currency transaction exposure for forecasted revenues and expenses in our 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 we use to hedge this exposure are designated as cash flow hedges. As of September 30, 2021 and December 31, 2020, the total notional amounts of these foreign exchange contracts were $898.5 million and $912.9 million, respectively. As of September 30, 2021, our foreign currency cash flow hedge instruments had maturity dates ranging from October 2021 to September 2023 and we had a net gain of $1.6 million recorded within accumulated other comprehensive income (loss) to be reclassified to revenues and expenses relating to these cash flow hedges as they mature in the next 12 months. As of December 31, 2020, our foreign currency cash flow hedge instruments had maturity dates ranging from January 2021 to December 2022 and we had a net loss of $35.4 million recorded within accumulated other comprehensive income (loss) to be reclassified to revenues and expenses relating to these cash flow hedges as they mature in the next 12 months. We enter into intercompany hedging instruments ("intercompany derivatives") with our wholly-owned subsidiaries in order to hedge certain forecasted revenues and expenses denominated in currencies other than the U.S. Dollar. Simultaneously, we enter into derivative contracts with unrelated third parties to externally hedge the net exposure created by such intercompany derivatives. We hedge the interest rate exposure created by anticipated fixed rate debt issuances through the use of treasury locks and swap locks (collectively, interest rate locks), which are designated as cash flow hedges. As of September 30, 2021, the total notional amount of interest rate locks outstanding was $350.0 million. As of December 31, 2020, we had no interest rate locks outstanding. During the nine months ended September 30, 2021, interest rate locks with a combined aggregate notional amount of $1.3 billion were settled related to the issuance of senior notes during the year. When interest rate locks are settled, any gain or loss from the transactions is deferred and included as a component of other comprehensive income (loss) and is amortized to interest expense over the term of the forecasted hedged transaction which is equivalent to the term of the interest rate locks. As of September 30, 2021 and December 31, 2020, we had a net loss of $4.2 million and $4.1 million, respectively, recorded within accumulated other comprehensive income (loss) to be reclassified to interest expense in the next 12 months for interest rate locks. The effect of cash flow hedges on accumulated other comprehensive income and the condensed consolidated statements of operations for the three and nine months ended September 30, 2021 and 2020 was as follows (in thousands): Amount of gain or (loss) recognized in accumulated other comprehensive income: Three Months Ended Nine Months Ended 2021 2020 2021 2020 Foreign currency forward and option contracts (included component) (1) $ 27,860 $ (40,770) $ 61,067 $ (35,092) Foreign currency option contracts (excluded component) (2) — 639 151 2,315 Interest rate locks 7,374 (2,420) 6,135 (29,302) Total $ 35,234 $ (42,551) $ 67,353 $ (62,079) Amount of gain or (loss) reclassified from accumulated other comprehensive income to income: Three Months Ended Nine Months Ended Location of gain or (loss) 2021 2020 2021 2020 Foreign currency forward contracts Revenues $ (11,863) $ 2,904 $ (41,397) $ 44,681 Foreign currency forward contracts Costs and operating expenses 5,872 (1,951) 21,659 (23,449) Interest rate locks Interest Expense (1,101) (731) (2,955) (473) Total $ (7,092) $ 222 $ (22,693) $ 20,759 Amount of gain or (loss) excluded from effectiveness testing included in income: Three Months Ended Nine Months Ended Location of gain or (loss) 2021 2020 2021 2020 Foreign currency option contracts (excluded component) (2) Revenues $ — $ (430) $ (244) $ (1,454) Total $ — $ (430) $ (244) $ (1,454) (1) Included component represents foreign exchange spot rates. (2) Excluded component represents option's time value. Derivatives Not Designated as Hedging Instruments Embedded Derivatives . We are deemed to have foreign currency forward contracts embedded in certain of our 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 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. Economic Hedges of Embedded Derivatives . We use foreign currency forward contracts to manage the foreign exchange risk associated with our 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 . We also use 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 our 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 both September 30, 2021 and December 31, 2020, the total notional amounts of these foreign currency contracts was $3.4 billion.

(2) As presented in our condensed consolidated balance sheets within other current liabilities and other liabilities. Offsetting Derivative Assets and Liabilities We enter into master netting agreements with our 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, we do 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 September 30, 2021 and December 31, 2020 (in thousands): Gross Amounts Offset in Gross Amounts Gross Amounts Offset in the Balance Sheet Net Amounts Gross Amounts not Offset in the Balance Sheet Net September 30, 2021 Derivative assets $ 190,938 $ — $ 190,938 $ (88,534) $ 102,404 Derivative liabilities 93,401 — 93,401 (88,534) 4,867 December 31, 2020 Derivative assets $ 38,447 $ — $ 38,447 $ (35,100) $ 3,347 Derivative liabilities 415,628 — 415,628 (35,100) 380,528

Fair Value Measurements	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) 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. Our financial assets and liabilities measured at fair value on a recurring basis as of September 30, 2021 and December 31, 2020 were as follows (in thousands): As of September 30, 2021 As of December 31, 2020 Fair Value Fair Value Fair Value Fair Value Level 1 Level 2 Level 1 Level 2 Assets: Money market and deposit accounts $ 390,997 $ 390,997 $ — $ 611,071 $ 611,071 $ — Publicly traded equity securities — — — 159 159 — Certificates of deposit — — — 4,373 — 4,373 Derivative instruments (1) 159,595 — 159,595 11,699 — 11,699 Total $ 550,592 $ 390,997 $ 159,595 $ 627,302 $ 611,230 $ 16,072 Liabilities: Derivative instruments (1) $ 75,780 $ — $ 75,780 $ 400,459 $ — $ 400,459 (1) Amounts are included within other current assets, other assets, others current liabilities and other liabilities in the condensed consolidated balance sheets. We did not have any nonfinancial assets or liabilities measured at fair value on a recurring basis as of September 30, 2021 and December 31, 2020. Other than the contingent consideration related to the EMEA 1 Joint Venture as described in Note 6 above, we did not have any Level 3 financial assets or financial liabilities measured at fair value on a recurring basis as of September 30, 2021 and December 31, 2020.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Purchase and Other Commitments As a result of our various IBX data center expansion projects, as of September 30, 2021, we were contractually committed for approximately $1.0 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 our customers for installation. We also had numerous other, non-capital purchase commitments in place as of September 30, 2021, such as commitments to purchase power in select locations through the remainder of 2021 and thereafter, and other open purchase orders for goods or services to be delivered or provided during the remainder of 2021 and thereafter. Such other miscellaneous purchase commitments totaled approximately $1.2 billion as of September 30, 2021. For further information on equity contribution commitments and lease commitments, see Note 6 and Note 9, respectively, above. Contingent Liabilities We estimate our 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, we record what we 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 our 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 our IBX data center leases or a municipality changing the assessment value in a jurisdiction and, as a result, our property tax obligations may vary from period to period. Based upon the most current facts and circumstances, we make the necessary property tax accruals for each of our reporting periods. However, revisions in our estimates of the potential or actual liability could materially impact our financial position, results of operations or cash flows. Our 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 an audit and appealing the tentative assessment in Brazil. The final settlement of the audit and the outcome of the appeal are uncertain and may not be resolved in our favor. We regularly assess the likelihood of adverse outcomes resulting from these examinations and appeals that would affect the adequacy of our 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 our expectations, the revision of the estimates of the potential or actual liabilities could materially impact our financial position, results of operations, or cash flows. Indemnification and Guarantor Arrangements As permitted under Delaware law, we have agreements whereby we indemnify our officers and directors for certain events or occurrences while the officer or director is, or was serving, at our request in such capacity. The term of the indemnification period is for the officer's or director's lifetime. The maximum potential amount of future payments we could be required to make under these indemnification agreements is unlimited; however, we have a director and officer insurance policy that could limit our exposure and enable us to recover a portion of any future amounts paid. As a result of our insurance policy that could limit our exposure and enable us to recover some or all of amounts paid, our estimated fair value of these indemnification agreements is minimal. We have no liabilities recorded for these agreements as of September 30, 2021. We enter into standard indemnification agreements in the ordinary course of business. Pursuant to these agreements, we indemnify, hold harmless, and agree to reimburse the indemnified party for losses suffered or incurred by the indemnified party, generally our business partners or customers, in connection with any U.S. patent, or any copyright or other intellectual property infringement claim by any third party with respect to our offerings. The term of these indemnification agreements is generally perpetual any time after execution of the agreement. The maximum potential amount of future payments we could be required to make under these indemnification agreements is unlimited; however, we have never incurred material costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, our estimated fair value of these agreements is minimal. We have no liabilities recorded for these agreements as of September 30, 2021. We enter into arrangements with our business partners, whereby the business partner agrees to provide services as a subcontractor for our installations. Accordingly, we enter into standard indemnification agreements with our customers, whereby we indemnify them for other acts, such as personal property damage, of our subcontractors. The maximum potential amount of future payments we could be required to make under these indemnification agreements is unlimited; however, we have general and umbrella insurance policies that could enable us to recover a portion of any amounts paid. We have never incurred material costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, our estimated fair value of these agreements is minimal. We have no liabilities recorded for these agreements as of September 30, 2021. We have service level commitment obligations to certain of our customers. As a result, service interruptions or significant equipment damage in our IBX data centers, whether or not within our control, could result in service level commitments to these customers. Our liability insurance may not be adequate to cover those expenses. In addition, any loss of services, equipment damage or inability to meet our service level commitment obligations could reduce the confidence of our customers and could consequently impair our ability to obtain and retain customers, which would adversely affect both our ability to generate revenues and our operating results. We generally have the ability to determine such service level credits prior to the associated revenue being recognized. We do not have significant liabilities in connection with service level credits as of September 30, 2021.

loss to net income. (2) We have two defined benefit pension plans covering all employees in two countries where such plan is mandated by law. Changes in foreign currencies can have a significant impact to our condensed consolidated balance sheets (as evidenced above in our foreign currency translation loss), as well as our 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 September 30, 2021, the U.S. Dollar was generally stronger relative to certain of the currencies of the foreign countries in which we operate as compared to December 31, 2020. Because of this, the U.S. Dollar had an overall unfavorable impact on our 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 nine months ended September 30, 2021 as reflected in the condensed consolidated statements of comprehensive income (loss). The volatility of the U.S. Dollar as compared to the other currencies in which we operate could have a significant impact on our condensed consolidated financial position and results of operations including the amount of revenue that we report in future periods. Common Stock In October 2020, we established an ATM program, under which we may, from time to time, offer and sell up to an aggregate of $1.5 billion of our common stock to or through sales agents in "at the market" transactions (the "2020 ATM Program"). For the three months ended September 30, 2021, we did not sell any shares under the 2020 ATM Program. For the nine months ended September 30, 2021, we sold 137,604 shares under the 2020 ATM Program, for approximately $99.6 million, net of payment of commissions to sales agents and other offering expenses. As of September 30, 2021, we had $1.4 billion available for sale under the 2020 ATM Program. For the three and nine months ended September 30, 2020, we sold 252,982 shares and 415,512 shares respectively, under our prior ATM program, for approximately $196.5 million and $298.3 million, respectively, net of payment of commissions to sales agents and other offering expenses. In May 2020, we issued and sold 2,587,500 shares of common stock in a public offering pursuant to a registration statement and a related prospectus and prospectus supplement. We received net proceeds of approximately $1.7 billion, net of underwriting discounts, commissions and offering expenses. Stock-Based Compensation For the nine months ended September 30, 2021, the Compensation Committee and/or the Stock Award Committee of our Board of Directors, as the case may be, approved the issuance of an aggregate of 735,818 shares of restricted stock units ("RSUs") to certain employees, including executive officers. These equity awards are subject to vesting provisions and have a weighted-average grant date fair value of $671.89 per share and a weighted-average requisite service period of 3.60 years. The valuation of RSUs with only a service condition or a service and performance condition require no significant assumptions as the fair value for these types of equity awards is based solely on the fair value of our stock price on the date of grant. We use revenues and adjusted funds from operations ("AFFO") per share as the performance measurements in the RSUs with both service and performance conditions that were granted in the nine months ended September 30, 2021. We use a Monte Carlo simulation option-pricing model to determine the fair value of RSUs with a service and market condition. We used total shareholder return ("TSR") as the performance measurement in the RSUs with a service and market condition that were granted in the nine months ended September 30, 2021. There were no significant changes in the assumptions used to determine the fair value of RSUs with a service and market condition that were granted in 2021 compared to the prior year.

Segment Reporting [Abstract]
Segment Information	Segment InformationWhile we have one primary line of business, which is the design, build-out and operation of IBX data centers, we have determined that we have three reportable segments comprised of our Americas, EMEA and Asia-Pacific geographic regions. Our chief operating decision-maker evaluates performance, makes operating decisions and allocates resources based on our revenues and adjusted EBITDA performance both on a consolidated basis and based on these three reportable segments. Intercompany transactions between segments are excluded for management reporting purposes.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events Declaration of dividends On November 3, 2021, we declared a quarterly cash dividend of $2.87 per share, which is payable on December 15, 2021 to our common stockholders of record as of the close of business on November 17, 2021. Asia-Pacific 2 Joint Venture On October 15, 2021, we entered into an agreement to form a joint venture in the form of a limited liability partnership with PGIM, to develop and operate xScale data centers in Asia-Pacific (the "Asia-Pacific 2 Joint Venture"). Upon closing, PGIM will contribute cash in exchange for an 80% partnership interest in the Asia-Pacific 2 Joint Venture. We will sell our SY9 data center site to the Asia-Pacific 2 Joint Venture in exchange for a 20% partnership interest in the Asia-Pacific 2 Joint Venture and cash proceeds. The transaction is expected to close in the fourth quarter of 2021, pending regulatory approval and other closing conditions. The assets and liabilities of the SY9 data center were classified as held for sale as of September 30, 2021 (see Note 5 above). Close of SP5 Sale On October 14, 2021, we completed the sale of our SP5 data center to the EMEA 2 Joint Venture for cash proceeds of approximately R$187.8 million, or $34.1 million at the exchange rate in effect on that date.

Basis of Presentation and Significant Accounting Policies (Policies)	9 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	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. In the preparation of our condensed consolidated financial statements, we have considered potential impacts of the COVID-19 pandemic on our critical and significant accounting estimates. There was no significant impact to our condensed consolidated financial statements. We will continue to evaluate the nature and extent of the potential impacts to our business and our condensed consolidated financial statements. Our condensed consolidated balance sheet data as of December 31, 2020 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"). 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 19, 2021. Results for the interim periods are not necessarily indicative of results for the entire fiscal year.
Consolidation	Consolidation The accompanying unaudited condensed consolidated financial statements include our acquisitions of two data centers in Mumbai, India from India operations of GPX Global Systems, Inc. ("GPX India") from September 1, 2021, 12 data center sites across Canada from BCE Inc. ("Bell") from October 1, 2020 and one additional data center site from November 2, 2020, Packet Host, Inc. (“Packet”) from March 2, 2020, and three data centers in Mexico acquired from Axtel S.A.B. de C.V ("Axtel") from January 8, 2020. 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 distributions made 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.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Accounting Standards Not Yet Adopted In October 2021, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2021-08 Business Combinations ("Topic 805"): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. The ASU requires contract assets and contract liabilities acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with ASC 606, Revenue from Contracts with Customers, as if it had originated the contracts. Under the current business combinations guidance, such assets and liabilities were recognized by the acquirer at fair value on the acquisition date. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022, with early adoption permitted. We are currently evaluating the extent of the impact of this ASU, but do not expect the adoption of this standard to have a significant impact on our condensed consolidated financial statements. In August 2020, FASB issued ASU 2020-06: Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40). The ASU simplifies the accounting for convertible instruments by reducing the number of accounting models for convertible debt instruments and convertible preferred stock and modifies the disclosure requirement for the convertible instruments. Additionally, this ASU improves the consistency of EPS calculations by eliminating the use of the treasury stock method to calculate diluted EPS for convertible instruments and clarifies certain areas under the current EPS guidance. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2021, with early adoption permitted at the beginning of the fiscal year after December 15, 2020. We are currently evaluating the extent of the impact of this ASU, but do not expect the adoption of this standard to have a significant impact on our condensed consolidated financial statements. Accounting Standards Adopted In December 2019, FASB issued 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. 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. On January 1, 2021, we adopted this ASU on a prospective basis and the adoption of this standard did not have an impact on our condensed consolidated financial statements. In March 2020, FASB issued ASU 2020-04, Reference Rate Reform ("Topic 848"): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. In addition, FASB issued ASU 2021-01, Reference Rate Reform ("Topic 848"), which clarifies the scope of Topic 848. Collectively, the guidance 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. ASU 2020-04 was effective for all entities as of March 12, 2020 through December 31, 2022 and ASU 2021-01 is effective upon issuance. We adopted these ASUs upon their respective issuances and there was no impact on our condensed consolidated financial statements as a result of adopting the guidance. We will evaluate our debt, derivative and lease contracts that may become eligible for modification relief and may apply the elections prospectively as needed.
Remaining performance obligations	Remaining performance obligations As of September 30, 2021, approximately $8.5 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 three 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 70% 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 contracts renewal. 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 deployments 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 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 we are considered the lessor.
Derivatives Designated as Hedging Instruments	Derivatives Designated as Hedging Instruments Net Investment Hedges. 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 September 30, 2021 and December 31, 2020, the total principal amounts of foreign currency debt obligations designated as net investment hedges were $1.5 billion and $1.9 billion, respectively. We also use cross-currency interest rate swaps, 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. As of September 30, 2021 and December 31, 2020, we had cross-currency interest rate swaps outstanding with notional amounts of $4.0 billion and $3.3 billion respectively, with maturity dates ranging through 2026. Cash Flow Hedges .
Derivatives Not Designated as Hedging Instruments	Derivatives Not Designated as Hedging Instruments Embedded Derivatives . We are deemed to have foreign currency forward contracts embedded in certain of our 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 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. Economic Hedges of Embedded Derivatives . We use foreign currency forward contracts to manage the foreign exchange risk associated with our 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	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) other than quoted market prices included within Level 1 that are observable, either directly or indirectly, for the assets or liabilities.
Segment Information	While we have one primary line of business, which is the design, build-out and operation of IBX data centers, we have determined that we have three reportable segments comprised of our Americas, EMEA and Asia-Pacific geographic regions. Our chief operating decision-maker evaluates performance, makes operating decisions and allocates resources based on our revenues and adjusted EBITDA performance both on a consolidated basis and based on these three reportable segments. Intercompany transactions between segments are excluded for management reporting purposes.
