Rackspace Inc. is a managed cloud computing company based in Windcrest, Texas, USA, a suburb of San Antonio, Texas. The company additionally has offices in Australia, the United Kingdom, Switzerland, Israel, The Netherlands, India, and Hong Kong, and data centres operating in Texas, Illinois, Virginia, the United Kingdom, Australia, and Hong Kong. The company's email and apps division operates from Blacksburg, VA; additional offices are located in Austin, Texas. In 2016, Rackspace closed its San Francisco office.


In 1996, Richard Yoo started a small Internet service provider called Cymitar Network Systems out of his garage flat in San Antonio, Texas. The company began doing application development work in addition to offering basic Internet access and web hosting. In 1997, Yoo brought on Dirk Elmendorf. When the company began to develop Internet applications as its primary business, the company was re-formed as Cymitar Technology Group. As Cymitar Technology Group grew, Patrick Condon was recruited from California and joined the team in 1998. Coincidentally, all three of the company's founders were students at one time at Trinity University in San Antonio.

Although the founders began as application developers for end users, they found that most companies didn't either know how or want to host their applications. The founders wanted to focus on application development–not hosting–but they were unable to find an opportunity to outsource the hosting work. Eventually, the founders realised that it would be better to create a product to serve the hosting need and launch it as a company. Rackspace was launched in October 1998 with Richard Yoo as its CEO. Although most hosting companies focused on the technology end of hosting, Rackspace created its "Fanatical Support" offering to focus on service and support. On March 28, 2000, Rackspace received funding through Norwest Venture Partners and Sequoia Capital. George J. Still, Jr., Managing Partner at Norwest, subsequently joined the Board of Directors.

In 2008, Rackspace moved their headquarters from a building once occupied by Datapoint Corporation to the then-unoccupied Windsor Park Mall in Windcrest, Texas. Rackspace's Chairman, Graham Weston, owned the Montgomery Ward building in the mall until 2006, when it was sold to a developer. The city of Windcrest purchased 111 acres (0.45 km2) south of the mall to create a residential and retail complex. The facility is located next to Roosevelt High School, and a large number of Roosevelt students intern at Rackspace.

The Fortune magazine's "Top 100 Best Companies to Work For 2008" placed Rackspace as #32 the first year that Rackspace applied for consideration. The company was praised for its transparency. Regular "Open Book" meetings are held where the top level leaders share in-depth financial information with all employees. In 2011 and 2013, the company was named as one of the top 100 places to work by Fortune.

On August 8, 2008, Rackspace opened for trading on the New York Stock Exchange under the ticker symbol "RAX" after its initial public offering (IPO) in which it raised $187.5 million. The initial public offering included 15,000,000 shares of its common stock at a price of $12.50 per share. The IPO didn't do well in the public market and lost about twenty percent of its initial price almost immediately.

At around 3:45PM CST December 18, 2009, Rackspace experienced an outage for customers using their Dallas-Fort Worth data center – including those of Rackspace Cloud.

On September 8, 2010, Rackspace received national attention when they decided to discontinue providing web hosting service to one of their customers, Dove World Outreach Center. This was in reaction to Dove World's pastor Terry Jones' plan to burn several copies of the Qur'an on the anniversary of the September eleventh attacks. Rackspace claims that this violated their company policy. This move came under criticism, notably from Terry Jones himself, who described it as an "indirect attack on our freedom of speech." Others questioned the appropriateness of Rackspace's action, stating that there's "absolutely no reason for web hosts to have an editorial policy, and this only gives Jones more attention, and makes him look more persecuted."

On June 3, 2011, Rackspace intervened in an application by Queensland host Rack Servers to trademark its business name in Australia.

On May 26, 2013, Author Bill Schley's book 'The UnStoppables', which was inspired by the culture at Rackspace, became a New York Times bestseller.

On May 15, 2014, Rackspace hired Morgan Stanley to assess strategic options including selling to or merging with additional technology companies.

On October 22, 2008, Rackspace announced it was purchasing cloud storage provider Jungle Disk and VPS provider SliceHost.

CloudU Credential

CloudU is a professional certification established by Rackspace. The designation certifies that individuals have demonstrated competency, knowledge, skills, and abilities in the blended discipline of cloud computing, through a rigorous qualification and testing program.

Business model

Rackspace has two primary lines of business; Cloud Servers and Dedicated Servers. Rackspace helps design, build, and operate workloads across both environments depending on the individual needs of the customer.

Cloud servers

The Managed Infrastructure service level provides a core set of services necessary to set customers up in the cloud, including architecture advice, security assistance, and code development assistance (through APIs and SDKs).

The Managed Operations support level provides all Managed Infrastructure services plus additional proactive support.

Dedicated servers

The Managed service level consists of on-demand support where proactive services are provided, but the customer can contact Rackspace when they need additional assistance.

The Intensive service level consists of proactive support where a large number of proactive services are provided, and customers receive additional consultations about their server configuration. Highly customised implementations generally fall under this level of support.

Involvement with additional companies

Rackspace launched ServerBeach in San Antonio in January 2003 as a lower-cost alternative for dedicated servers designed for technology hobbyists who want flexibility and reliability. Richard Yoo was a catalyst in the startup of ServerBeach. A bandwidth and colocation provider, Peer 1 Hosting now known as Cogeco Peer 1, purchased ServerBeach in October 2004 for $7.5 Million. Peer 1 Hosting entered the UK managed hosting market in January 2009 and the ServerBeach brand now competes directly with the UK arm of Rackspace, run by Dominic Monkhouse, former managing director of Rackspace Limited.

In October 2006, Mosso Inc. was launched, which experimented with white-labeling hosting services. Eventually, the division became the foundation for the Rackspace Cloud Computing offering.

On October 1, 2007, Rackspace acquired Webmail.us, a private e-mail hosting firm located in Blacksburg, VA. Originally branded as Mailtrust on May 20, 2009, it became part of the newly formed Email and Apps division of Rackspace.

On October 22, 2008, Rackspace acquired Slicehost, a provider of virtual servers and Jungle Disk, a provider of online backup software and services.

Expansion into the Asia Pacific region

The company is experiencing growth in the Asian marketplace. The Asian office is a natural step in Rackspace's expansion outside the U.S. and London to cater for worldwide customers’ needs in Hong Kong / China. Currently, rackspace holds 1.60% market share worldwide. Rackspace selected Hong Kong as the Asia Pacific regional office in part because of its reputation within the global business economy, its IT infrastructure, multiple telecommunication providers and rich talent pool. Rackspace additionally solicited feedback from its current customer base in the Asia Pacific region, and the majority of those respondents confirmed their preference for doing business in Hong Kong.


Rackspace serves customers worldwide and has offices in the United States, Australia, United Kingdom, The Netherlands, Switzerland, Israel, India, and Hong Kong, and data centres in the United States, Australia, United Kingdom, and Hong Kong. Rackspace Benelux in Amsterdam opened its offices in October 2007. Rackspace Australia in Sydney opened its offices in March 2009.
