CEO Taylor Rhodes disclosed the outlines of the plan in a blog post on Tuesday. The company confirmed to the San Antonio Business Journal that 276 of its 4,600 U.S. positions would be affected. A company spokeswoman reaffirmed the 6% figure to Fortune separately, without any other specifics.
“The U.S. layoffs and proposed international reductions are personally painful, but they are necessary and manageable,” Rhodes wrote, adding that he is confident they can be accomplished without hurting customer service.

Over the past few years, however, Rackspace has evolved to become more of a partner, as well as a competitor, to those two services.
