The SAVVIS ProActive Network^SM is designed to offer SAVVIS customers unmatched speed, performance and reliability on a global basis. Whether it be for Internet, VPN/MDN or Financial Solution services, the SAVVIS Proactive Network is architected to meet customer's most demanding bandwidth and performance requirements.

With state-of-the-art Lucent ATM switches along with Cisco and Nortel Networks routers in major cities throughout Europe, Africa, Asia, the Pacific Rim, and the Americas, the SAVVIS Proactive Network is the largest next generation IP/ATM network in the world.

In addition, SAVVIS is the only internetworking service provider to offer its customers global end-to-end Quality of Service (QoS). SAVVIS has established an innovative, multi-tiered QoS strategy to allow customers to minimize latency, packet loss, variation, and error rates across their Virtual Private Networks. Customers can select from Bronze, Silver, Gold, and Platinum service levels, depending on their application, service level need, and dependency on transmission.

To deliver high-performance Internet service, SAVVIS pioneered the use of Private Network Access Points (PrivateNAPs^SM), where SAVVIS exchanges data through dynamic "on-net" connections with other major Internet network providers. This dramatically minimizes latency and packet loss commonly associated with many other networks. SAVVIS uses fault tolerant facilities and a fully meshed network design to provide maximum reliability. In the event of an outage, the SAVVIS Proactive Network instantly reroutes data to ensure consistent flow with no downtime. SAVVIS maintains multiple DS-3/OC-3 circuits to each POP and three or more DS-3/OC-3 interconnects and multiple private peers at each of its PrivateNAPs.

The SAVVIS Proactive Network has been consistently rated #1 in the world by Keynote Systems, Inc., as reported in the Boardwatch Internet Backbone Performance Index, receiving eight of the 16 first place monthly rankings. SAVVIS swept the ratings in every category, including Best Download Time, Best Performance Under Load, Best Total Performance and Best Value on the Internet.
