Global, Rich-media CDN to Help Address Rapid Rise in Site Access Numbers

TOKYO, JAPAN – NOV. 28, 2007 - Limelight Networks (NASDAQ: LLNW), the leading content delivery network (CDN) for digital media, announced today that Nikkei Digital Media, Inc. has selected Limelight Networks’ high performance CDN for its NIKKEI NET site, which is one of the largest news sites in Japan. By handling the delivery of video and still image content carried on NIKKEI NET, Limelight Networks will help to ease the load on NIKKEI NET servers.

About Limelight Networks’ High Performance Digital CDN

Limelight Networks’ CDN for delivering digital media boasts a high level of scalability that enables the reliable handling of large media files and large content libraries. Even in the event of intense spikes in viewership owing to major breaking news stories, Limelight Networks’ CDN prevents media access failures and delays in display caused by increased load on servers, providing users with a consistent and high quality viewing experience.

Delivering rich media to a large audience is difficult, and building the infrastructure capable of handling such access levels also requires considerable expenditure. Using Limelight Networks’ CDN enables customers to respond to unexpectedly heavy network traffic while keeping investment in server systems and other in-house infrastructure to a minimum.
