ATLANTA, GA – (May 20, 2008) – Internap Network Services Corporation (NASDAQ: INAP), a global provider of end-to-end Internet business solutions, announced today that New York Media, publishers of the award-winning New York Magazine and nymag.com, has expanded its service portfolio from Internap to include content delivery network (CDN) to improve the viewing experience of rich media content and attract an international audience. As a result, nymag.com can avoid being crippled by the “flash crowds” that can accompany a hot story and readers experience superior up time and an improved browsing experience.

Nymag.com, with over five million unique monthly visitors, has been powered by Internap’s Performance IP™ network since 2004. The organization recognized an opportunity to grow its reader base, increase the number of online page views and attract new advertising dollars by adding rich media to the Web site. Internap’s CDN services were easily combined with the installed network services to create a seamless communications backbone for delivering compelling content to the magazine’s online audience. This end-to-end solution enables nymag.com to dynamically load media onto the CDN, distribute engaging stories to its visitors and manage media content based on business rules.

“For companies seeking to enhance their Web sites with rich media, Internap’s CDN is a perfect complement to their Performance IP networking services,” said Nathan Butler, senior network engineer at nymag.com. “Internap’s award-winning customer service program combined with their route optimized network service helped us build a rich media experience for nymag.com’s growing base of over five million unique monthly visitors and grow our audience internationally.”

Internap’s CDN, Performance IP networking and data center colocation are fully integrated and supported by a 100 percent Service Level Agreement (SLA). Customers can select individual services or a bundled solution now or as their business needs grow. Internap’s sophisticated route management technology provides the optimized network backbone for Internap’s services, successfully alleviating Internet down time while delivering ubiquitous, high-quality applications and content.

“New York Media is a publishing icon that is using rich media to drive traffic to their flagship website nymag.com and attract new advertising revenue,” said James P. DeBlasio, president and chief executive officer at Internap. “Nymag.com can count on Internap’s Performance IP and CDN solutions to provide the global network infrastructure and reliable service needed to enable this strategic initiative.”

According to the Magazine Publishers of America, more than 67.5 million unique visitors visited consumer magazine Web sites in the fourth quarter of 2007. Through Internap’s technology, online magazine readers worldwide enjoy successful real-time Web communications that are not compromised by unexpected performance dips due to global network congestion.
