"The board is grateful to Phil for his service to the company,
particularly during these challenging economic times," said Jim Ousley,
interim CEO of Savvis. "Phil built a solid foundation for Savvis, as he
transformed it into an IT infrastructure services company with a dedicated
focus on cloud computing. He helped put in place a strong, experienced and
stable management team and a strategic vision for the future, which we plan
to expand on in 2010."

"We would like to take this time to reaffirm our 2009 guidance, which
calls for adjusted EBITDA of US$215 to US$220 million, total cash CAPEX
guidance between US$120 and US$140 million, cash interest expense of
approximately US$40 to US$45 million, and adjusted free cash flow of US$40 to
US$50 million," said Greg Freiberg, chief financial officer of Savvis. "We
will provide our 2009 results - including details around fourth quarter
bookings, which were the best the company has seen in 18 months - and
specifics regarding our 2010 plan, during our fourth quarter 2009 earnings
call, which will be held on February 3."

"I joined Savvis in 2006, with the objective to build a better company
and to develop a world class team dedicated to meeting and exceeding our
customers' diverse requirements for IT infrastructure services," said Phil
Koen. "In consultation with our board of directors - and knowing we have a
very strong leadership team in place - this is an excellent time for me to
move on to a new opportunity and to watch Savvis continue to grow and excel."
