Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Purchase Commitments Non-cancelable purchase commitments primarily relate to costs associated with our data centers, including bandwidth and electricity, as well as commitments for consulting services and to purchase hardware and to prepay for certain software licenses. The agreements can generally extend up to five years and provide for either penalties for early termination or may require minimum commitments for the remaining term. The minimum commitments for all of these agreements as of December 31, 2013 approximated $50.5 million, $26.0 million, $1.0 million, $0.7 million and $0.2 million for the years ended December 31, 2014, 2015, 2016, 2017 and 2018, respectively. We also have purchase orders and construction contracts primarily related to data center equipment and facility build-outs. We generally have the right to cancel these open purchase orders prior to delivery or terminate the contracts without cause. Legal Proceedings We are party to various legal and administrative proceedings, which we consider routine and incidental to our business. Although the outcome of these matters is currently not determinable, management expects that any losses that are incurred as a result of these matters, which are in excess of amounts already accrued in its consolidated balance sheet, would not be material to the financial statements as a whole. In addition, we were involved in the following legal proceeding as of December 31, 2013: On October 22, 2008, Benjamin E. Rodriguez D/B/A Management and Business Advisors vs. Rackspace Hosting, Inc. and Graham Weston was filed in the 37th District Court in Bexar County, Texas by a former consultant to the company, Benjamin E. Rodriguez. The suit alleged breach of an oral agreement to issue Mr. Rodriguez a 1% interest in our stock in the form of options or warrants for compensation for services he was engaged to perform for us. This matter was settled as of February 19, 2014, and there was not a material difference between the settlement amount and the amount for which we had accrued for the matter in our consolidated financial statements. We are also a party to various claims that certain of our products, services, and technologies infringe the intellectual property rights of others. Adverse results in these lawsuits may include awards of substantial monetary damages, costly royalty or licensing agreements, or orders preventing us from offering certain features, products, or services, and may also cause us to change our business practices and require development of non-infringing products or technologies, which could result in a loss of revenue for us and otherwise harm our business. We have disputed the allegations of wrongdoing in these proceedings and intend to vigorously defend ourselves in all such matters. We cannot predict the impact, if any, that any of the matters described above may have on our business, results of operations, financial position, or cash flows. Because of the inherent uncertainties of such matters, including the early stage and lack of specific damage claims in many of them, we cannot estimate the range of possible losses from them. Indemnifications 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 limits our exposure and enables us to recover a portion of any future amounts paid. As a result of the insurance policy coverage, we believe the estimated fair value of these indemnification agreements is minimal. We had no significant liabilities recorded for these agreements as of December 31, 2012 or 2013. Additionally, in the normal course of business, we indemnify certain parties, including customers, vendors and lessors, with respect to certain matters. We have agreed to hold certain parties harmless against losses arising from a breach of representations or covenants or out of intellectual property infringement or other claims made against certain parties. These agreements may limit the time within which an indemnification claim can be made and the amount of the claim. We had no significant liabilities recorded for these agreements as of December 31, 2012 or 2013. Incentive Arrangements In August 2007, we entered into a lease for our corporate headquarters. In connection with this lease, we also entered into a Master Economic Incentives Agreement ("MEIA") with the Cities of Windcrest and San Antonio, Texas; Bexar County; and certain other parties, pursuant to which we agreed to locate existing and future employees at the new facility location. The agreement required that we meet certain employment levels each year in exchange for a 14-year exemption from most of the property taxes associated with the property. If we fail to meet these job creation requirements, we could lose a portion or all of the tax exemption provided during the 14-year period and would then be obligated to repay the exemption amount. We have met the requirements for the employment level for the year ended December 31, 2013, and we believe that it is probable that we will continue to meet the requirements throughout the exemption period. We elected to begin the exemption period in 2009. Further, we entered into an agreement with the State of Texas, under which we received $5.0 million in 2007 and $3.5 million in 2012 and may receive up to an additional $13.5 million from the Texas Enterprise Fund in multiple installments, provided that we meet certain new job levels in the State of Texas. We are responsible for maintaining the jobs until January 2022. If we eliminate jobs for which we have drawn funds, we are subject to a clawback on the amounts we have drawn plus 3.4% interest on such amounts per year. As of December 31, 2013, the $8.5 million received was deferred and recorded as other non-current liabilities. Amounts will be recognized into income upon the achievement of the performance criteria and the determination that the cash is no longer refundable to the State of Texas.
