ST. LOUIS -- SAVVIS To Disconnect An Estimated 40 Spammers Identified by Spamhaus

SAVVIS Communications (NASDAQ:SVVS), a leading global IT utility, announced today that its strong anti-spam policies will apply to all operations acquired through its March 2004 purchase of the assets of Cable & Wireless America (CWA). In addition, after close consultation with Spamhaus, a worldwide organization of spam fighters, SAVVIS is adopting Spamhaus' Register of Know Spam Operations (ROKSO) database as a principal metric for ensuring that the SAVVIS global IT infrastructure does not promote or condone spamming.

SAVVIS, long recognized for having one of the most stringent Acceptable Use Policies (AUP) regarding spam in the industry, has been integrating the assets it acquired from CWA in March 2004. While the acquisition brought SAVVIS 3,000 new enterprise customers, 15 data centers, deep consulting and operations expertise, and a Tier 1 OC-192 Internet backbone, it also included approximately 40 spam offenders that have been listed in the Spamhaus ROKSO database (some of these offenders are listed multiple times). SAVVIS will use the ROKSO "three strikes" list to help identify and proactively disconnect spam operations. Collectively, these offenders represent an immaterial portion of SAVVIS' revenue.

The ROKSO database collates information and evidence on known spam operations that have had their services terminated by a minimum of three consecutive Internet Service Providers for serious spam offenses. According to Spamhaus, 90% of spam received by Internet users in North America and Europe can be traced to a group of approximately 200 known spam operations, almost all of which are listed in the ROKSO database. These spam operations consist of an estimated 500-600 professional spammers loosely grouped into gangs ("spam gangs"), many or most of whom are operating illegally and move from network to network, seeking out Internet Service Providers ("ISPs") known for lax enforcement of anti-spam policies.

"Spamhaus has long recognized SAVVIS as a 'White Hat Network' with exemplary policies and procedures to control the proliferation of spam," said Steve Linford, CEO and Founder of the Spamhaus Project. "We are pleased to work with SAVVIS to fight against spam and encourage others in the industry to adopt their leadership model."

SAVVIS is rated as the #2 market share leader in Web hosting by industry analyst IDC and the #1 provider of network-based IP VPNs by analyst In-Stat/MDR. Its Internet backbone services approximately 30% of the world's Internet routes. With over 6,000 enterprise clients, SAVVIS is a leader in delivering IT services to businesses.

"SAVVIS has always been, and will always be, anti-spam," said Rob McCormick, Chairman and CEO of SAVVIS. "Extending our anti-spam policies and procedures to our recently acquired assets is an important part of the CWA integration process. Our relationship with Spamhaus, builder of the world's most respected spam blocklist, will allow us to continue leading the industry fight against spam."
