Sigster Selects Internap for its Social Gaming Environment

Internap’s intelligent IP routing and data center services provide social gaming company with the ability to deliver immersive, high-quality gaming experience on-demand from any device

ATLANTA, November 17, 2009 — Internap Network Services Corporation (NASDAQ: INAP), a global provider of end-to-end Internet business solutions, today announced that new, cross-platform social gaming company Sigster is using its Internap Performance IP^™ network and managed hosting services to provide a scalable, secure worldwide gaming infrastructure with guaranteed performance and uptime. The Internap network services and managed infrastructure will ensure a seamless experience for Sigster’s massive multi-player online role-playing games (MMORPGs) – beginning with the newly-released Urban War – which includes advanced community features and on-demand access from multiple social networking platforms and mobile devices.

Combining traditional role-playing components with full-fledged social media features, Sigster’s Urban War provides a dynamic street battle experience that lets users chat during games, post to users’ walls, and access user profiles and friend lists. Users can control how and where they play games and communicate with friends – both during and outside of game-playing – through one universal account that can currently be accessed from Facebook, MySpace, UrbanWar.com and from the iPhone® in the near future. Internap’s bundled Performance IP and managed hosting solutions provide a networked infrastructure that is optimized for the intensive connectivity, availability and performance requirements of Urban War’s immersive, real-time social gaming experience.

“The success of interactive, alternate reality gaming is directly tied to the reliability and performance of the underlying IP network. Basically, the game is only as good as the network delivering it. If the graphics render slowly or real-time communications are delayed, people simply won’t play,” said Eric Signorile, founder and CEO of Sigster. “After considering various competitive solutions, the combination of Internap’s Performance IP and managed hosting solutions was an obvious choice, providing us with guaranteed network performance and a secure, scalable hosting environment for Urban War and future games.”

Internap’s Performance IP service is based on its patented MIRO^™ (Managed Internet Route Optimizer) network optimization technology. Carrying a 100 percent performance SLA (service level agreement), Performance IP dynamically identifies the best path for Internet traffic through intelligent consideration of characteristics like latency, packet loss and route stability. Internap’s data center services provide colocation and managed hosting offerings, including performance bandwidth, virtualized hosting, managed storage and data protection services, with platforms extending to nearly 60 locations globally.

“As the gaming industry continues to rapidly incorporate the software-as-a-service model, with users accessing games – as well as more complex community capabilities like real-time chat and texting – from any device, the bar is also raised for the IP networking infrastructure,” said Peter Evans, senior vice president of marketing at Internap. “With Internap’s Performance IP and managed hosting solutions, enterprises, including advanced gaming companies like Sigster, are assured of a high-performing network architecture that can deliver on the robust capabilities of today’s growing cross-platform, cloud-based environments.
