ATLANTA, GA – (January 4, 2007) – Internap Network Services Corporation (NASDAQ: INAP), a global provider of end-to-end Internet business solutions, today announced its intelligent routing and IP technology is being leveraged by GameRail® to provide gamers with a superior online experience. Internap helps aggregate local broadband traffic and activity on to GameRail’s nationwide private network, which connects users directly to game sites.

GameRail operates a nationwide private broadband network designed specifically for multiplayer gaming online, delivering superior performance options in the $7 billion entertainment software industry that saw 250 million units sold in 20051. The network is dedicated to decreasing latency and improving game play through GameRail’s patent pending Partial Bypass Overlay Network (PBON) optimization for Real Time applications. GameRail’s PBON allows users to bypass traditional Internet connections that can degrade performance. As a result of integrating Internap’s technology for localized aggregation, GameRail customers are equipped with a competitive advantage for gaming, which emerges from improved network performance and reliability.

“When 20 milliseconds is a matter of ‘life and death’– winning and losing – for an online gamer, latency, packet loss and jitter can ruin the playing experience,” said Mark Senda, chief executive officer for GameRail. “Internap’s optimized network performance solutions allow us to provide localized ingress and egress connection speeds to three milliseconds, maximizing the flow of real-time Web traffic while optimizing game play.”

GameRail has direct connect peering relationships with the leading national, super-regional and local Game Server Providers with over 80% of First Person Shooter/Real Time Strategy gaming servers attached directly to the company’s private, nationwide network. Internap’s solutions ensure that residential broadband users of any and all carriers are able to enjoy the optimum gaming experience. Additionally, GameRail features private peering to route traffic away from the Internet and onto its private backbone.

“GameRail has a unique and superior online gaming solution and we are thrilled to work with the company to help them evolve,” said Tim Sullivan, chief technology officer for Internap. “As a Web-reliant enterprise, GameRail’s use of our innovative, proprietary technology is a significant proof point of the power of our resources for Internet-based business.”
