Rackspace Hosting, Inc. Comment Letter dated April 23, 2010

Ladies and Gentlemen:

We are in receipt of the comment letter dated April 23, 2010 (the “Comment Letter”) relating to the filing by Rackspace Hosting, Inc. (“Rackspace” or the “Company”) of its Annual Report on Form 10-K for the Fiscal Year Ended December 31, 2009 (the “Annual Report”). It is our understanding that the letter was faxed to a facsimile machine of the Company on that date and also mailed to the attention of A. Lanham Napier, the Rackspace Chief Executive Officer and President. Unfortunately, the Rackspace legal counsel handling SEC matters did not receive this correspondence until the afternoon of Thursday, June 10, 2010. The original fax, which we believe was sent to an unmanned general facsimile machine, was never located, and the letter was diverted into a general mail stack which we were able to locate after a diligent search on June 11, 2010. We have since reviewed internal procedures relating to the receipt of this type of correspondence to help avoid any such delay from occurring in the future. We have also attempted to update all potential sources of public contact information to provide direct access to our legal department (and to our outside SEC counsel for SEC matters). Further to this, we request that the Division of Corporate Finance update any database contact information for Rackspace as set forth below, or provide further guidance to the Company on what databases are used by the SEC for contact purposes so that the Company can update these using internal resources.
