Digital Island to Deploy Powerful Content Distributors That Reach

More Than 500,000 Road Runner Customers

Digital Island, Inc. (Nasdaq:ISLD), a leading global e-Business Delivery Network, announced today a strategic relationship with Road Runner, in which Digital Island will integrate its content delivery services into Road Runner's broadband cable network to facilitate content delivery in key U.S. markets - extending Digital Island's ability to deliver a fast, guaranteed and rich infrastructure capable of supporting the demands of interactive e-Business.

"This agreement with Road Runner gives Digital Island's customers direct access to an emerging gold class of Internet users who are sophisticated enough to appreciate the high quality of service that Road Runner provides for an optimal e-Business experience," said Ruann F. Ernst, chairman and CEO of Digital Island. "Our new relationship with Road Runner clearly illustrates the benefits of content distribution coupled with a back-end transaction engine in order to reach a coveted demographic audience."
