HERNDON, VA – August 4, 2003 – SAVVIS Communications (NASDAQ: SVVS), a global managed services provider, today announced that it is delivering private multicast services over its award-winning Intelligent IP NetworkSM. SAVVIS has been using multicast technology for over five years to deliver real-time financial market data. Now SAVVIS is making private multicast services available to businesses across all industries that want to deliver streaming applications to subscribers.

“Demand for multicast is expanding, as it is ideal for transporting streaming data to a variety of end users and subscribers,” said Zeus Kerravala, Vice President, The Yankee Group. “Until now, multicast was only available using the Internet, which could not provide the reliability, performance, and security required by mission-critical applications. SAVVIS’ private multicast service, delivered over SAVVIS’ proven high-availability global network, is a powerful network and hosting platform for cost effectively delivering streaming applications.”

A streaming application is defined as a continuous feed of text, voice, or video to a group of subscribers. SAVVIS’ private multicast service offers high availability, security and cost effectiveness for companies with mission-critical streaming applications. For example, in the financial services industry, financial market data is collected and consolidated in real-time from the trading venues around the world and distributed to brokers and dealers. In healthcare, surgeries are viewed in real-time by students and experts to improve the outcomes of procedures. In media, private video broadcasts are distributed to thousands of viewers.

“Moneyline Telerate has a long history of leveraging advanced technology to deliver value-added information and transaction services for the capital markets,” said Larry Landau, Senior Vice President for Global Network and Operations for Moneyline Telerate. “SAVVIS' Private Multicast service is essential for Moneyline Telerate to distribute real-time financial market data to our clients around the world, with negligible latency and with the flexibility to easily adjust for the ever increasing bandwidth required by the global financial markets.”

Private Multicast is fully integrated with SAVVIS’ global private network, which spans 45 countries, and with its data centers in the US, Europe, and Asia. This infrastructure is combined with SAVVIS’ engineering and implementation skills, monitoring systems, and award-winning customer service to deliver a portfolio of managed network, hosting and application services products.

“SAVVIS’ global infrastructure and management systems provide a solid platform for deploying multicast technology,” said Jack Finlayson, President and COO of SAVVIS. “Our private network delivers high-availability, performance, and security, and multicast offers cost-effective distribution of streaming real-time data and video.”
