ATLANTA, GA – (May 6, 2008) – Internap Network Services Corporation (NASDAQ: INAP), a global provider of end-to-end Internet business solutions, announced today that Rockfish Interactive, a leading, full-service Web development firm, has selected Internap’s Managed Server and Content Delivery Network (CDN) to rapidly deploy interactive, Web-based applications for its expanding portfolio of Fortune 500 customers.

The company builds online applications, including Web sites, blogs, Intranets and extranets, helping its customers meet their business goals creatively.

“In this day and age, it’s critical to present customers with an engaging online presence that commands their attention,” said Kenny Tomlin, founder and chief executive officer at Rockfish Interactive. “Internap’s CDN makes it possible for us to ensure our customers’ experiences are consistently of the highest quality, so they can succeed by standing out from the competition. Its open APIs (application programming interfaces) integrate well with our existing infrastructure, enabling us to focus on maximizing usability and design for the applications we create. We’ve found an ideal technology provider in Internap.”

Internap’s global 100 percent Service Level Agreement (SLA)-supported CDN, which recently expanded by 12 new points of presence (PoPs) to a total of 21 PoPs in North America, Europe and Hong Kong, provides customers with the ability to efficiently deliver online content. The open API allows Rockfish Interactive to seamlessly combine Internap’s CDN with existing systems and programming languages. The company’s fully scalable Managed Server solutions, including its streaming services, enable Rockfish Interactive to ensure a high-quality user experience despite the geographic location of its customers.

“Rockfish Interactive’s impressive customer base reflects the firm’s great achievements in the Web-development space,” said Tim Sullivan, chief technology officer at Internap. “For today’s enterprises, every Web-based application is mission-critical; downtime equals money lost.
