Accounting Policies [Abstract]
Principles of Consolidation	The unaudited consolidated financial statements include the accounts of Rackspace Technology, Inc. and our wholly-owned subsidiaries. Intercompany transactions and balances have been eliminated in consolidation.
Unaudited Interim Financial Information	Unaudited Interim Financial Information The unaudited consolidated financial statements as of March 31, 2022, and for the three months ended March 31, 2021 and 2022, have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information. Accordingly, certain financial information and disclosures required for financial statements prepared under GAAP have been omitted in accordance with the Securities and Exchange Commission ("SEC") disclosure rules and regulations that permit reduced disclosure for interim periods. These unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the related notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2021 ("Annual Report"). The unaudited interim consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements included in our Annual Report and, in the opinion of management, reflect all adjustments, which include normal recurring adjustments, necessary for a fair statement of our financial position as of March 31, 2022, and our results of operations, cash flows and stockholders' equity for the three months ended March 31, 2021 and 2022. The results of operations for the three months ended March 31, 2022 are not necessarily indicative of the results of operations to be expected for the year ending December 31, 2022, or for any other interim period, or for any other future year.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenue and expenses, and related disclosures of contingent assets and liabilities in the consolidated financial statements and accompanying notes. On an ongoing basis, we evaluate our estimates, including those related to the allowance for doubtful accounts, useful lives of property, equipment and software, software capitalization, incremental borrowing rates for lease liability measurement, fair values of intangible assets and reporting units, useful lives of intangible assets, share-based compensation, contingencies, and income taxes, among others. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could differ from our estimates.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Adopted Business Combinations In October 2021, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2021-08, Business Combinations (ASC 805) - Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. ASU 2021-08 requires that an entity (acquirer) recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Accounting Standards Codification No. 606, Revenue from Contracts with Customers ("ASC 606"). At the acquisition date, an acquirer should account for the related revenue contracts in accordance with ASC 606 as if it had originated the contracts. To achieve this, an acquirer may assess how the acquiree applied ASC 606 to determine what to record for the acquired revenue contracts. This standard allows the company a practical expedient to remove the requirement to measure and recognize such contracts in accordance with ASC 606. The guidance is applied prospectively upon adoption. We early adopted this guidance on January 1, 2022 and applied the practical expedient to our accounting for the acquisition of Just Analytics. The adoption of the guidance did not have a material impact on our consolidated financial statements. Not Yet Adopted Reference Rate Reform The United Kingdom's Financial Conduct Authority, which regulates the London Interbank Offered Rate ("LIBOR"), announced that it will not compel panel banks to contribute to the overnight 1, 3, 6 and 12 months U.S. dollar LIBOR tenors after June 30, 2023 and all other tenors after December 31, 2021. U.S. dollar LIBOR may be replaced by the Secured Overnight Financing Rate or other benchmark rates over the next several years. In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (ASC 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting containing practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts. The guidance in ASU 2020-04 is optional and may be applied from March 12, 2020 through December 31, 2022 as reference rate reform activities occur. In January 2021, the FASB issued an update that provides supplemental guidance and clarification of the reference rate reform. We have elected to apply certain practical expedients in the past. We continue to evaluate the impact of the guidance and may apply other elections prior to December 31, 2022, as applicable, as additional changes in the market occur. Currently, borrowings under our Senior Facilities use LIBOR as a benchmark for establishing the applicable interest rate, but the First Lien Credit Agreement includes provisions relating to the future discontinuance of LIBOR and sets forth mechanics for establishing the replacement of LIBOR with an alternative benchmark rate.
Net Loss Per Share	Net Loss Per ShareBasic net loss per share is calculated by dividing net loss attributable to common stockholders by the weighted average shares outstanding during the period.
Derivatives	Derivatives We utilize derivative instruments, including interest rate swap agreements, to manage our exposure to interest rate risk. We only hold such instruments for economic hedging purposes, not for speculative or trading purposes. Our derivative instruments are transacted only with highly-rated institutions, which reduces our exposure to credit risk in the event of nonperformance. Interest Rate Swaps We are exposed to interest rate risk associated with fluctuations in interest rates on the floating-rate Term Loan Facility. The objective in using interest rate derivatives is to manage our exposure to interest rate movements. To accomplish this objective, we have entered into interest rate swap agreements as part of our interest rate risk management strategy. Interest rate swaps involve the receipt of variable amounts from a counterparty in exchange for the company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. On a quarterly basis, we net settle with the counterparty for the difference between the fixed rate specified in each swap agreement and the variable rate based upon the three-month LIBOR as applied to the notional amount of the swap. The cash flow hedges were expected to be highly effective on the designation date and, on a quarterly basis, we performed retrospective and prospective regression assessments to determine whether the cash flow hedges continue to be highly effective. As long as the cash flow hedges are highly effective, changes in fair value are recorded to "Accumulated other comprehensive income (loss)" in the Consolidated Balance Sheets and reclassified to "Interest expense" in the period when the underlying transaction affects earnings. The income tax effects of cash flow hedges are released from "Accumulated other comprehensive income (loss)" in the period when the underlying transaction affects earnings. Any stranded income tax effects are released from “Accumulated other comprehensive income (loss)” into “Benefit (provision) for income taxes” under the portfolio approach.
