FOR IMMEDIATE RELEASE

Complete Service Offering Enables Direct Access to 30 Percent of the Top Internet Sites Fully Redundant Nationwide Backbone and Comprehensive Peering Relationships

ISPCON SPRING '99 - BALTIMORE, April 27, 1999 - Exodus Communications^TM, Inc. (NASDAQ: EXDS), a leading provider of Internet system and network management solutions for enterprises with mission-critical Internet operations, today unveiled the Exodus™ Internet Service Provider (ISP) Program. The new program includes two service packages designed to help service providers cut costs on Internet infrastructure, such as Internet bandwidth, Internet Data Centers (IDCs) and 24 x 7 personnel. Service providers can take advantage of Exodus' leadership and expertise in managing Internet infrastructure so they can focus on growing their business. In addition, the new ISP offerings can improve customer access to the content hosted on the Exodus network.

According to a recent eStats study, it is estimated that the number of Internet users in the United States will nearly double from 47 million in 1998 to 85 million by the year 2000. Service providers are learning that a key component to expanding their business is to guarantee smooth and efficient Internet operations to their customers. Instead of investing in capital to build IDCs and acquiring Internet bandwidth, service providers can easily take advantage of the resources already in place at Exodus. Exodus has the most comprehensive and high bandwidth public and private peering relationships available and a fully redundant nationwide backbone of fiber carriers to every Exodus IDC.

"If service providers cannot scale to handle the exponential growth of Web site traffic, they will not be able to grow their business, " said Ellen M. Hancock, president and CEO of Exodus. "Through our Service Provider Program, we're enabling these service providers to immediately achieve scale that would be very difficult to establish on their own. By taking advantage of the Exodus infrastructure, they can quickly accommodate rapid growth and scale to handle heavy traffic."

Exodus' nationwide network offers maximum Internet backbone performance and best-of-breed Internet services at significant cost savings. Service providers gain a nationwide private backbone with Exodus, including OC-3 and OC-12 capacity, and access to all of the network exchange points (NAPs). Exodus offers an extensive peering portfolio, with more than 40 private peering relationships and more than 120 public peering relationships.
