ATLANTA, GA – (October 2, 2007) – Internap Network Services Corporation (NASDAQ: INAP), a global provider of end-to-end Internet business solutions, today announced the launch of its managed server services, a new addition to the company’s suite of content delivery network (CDN) solutions. The managed servers enable CDN customers to further rely on Internap’s expertise for their Web-based businesses while ensuring faster time to market.

As an addition to the company’s robust CDN solutions, customers can lease servers on a contracted, 
month-to-month basis, resulting in lower initial capital expenditure than purchasing servers directly. In addition to Internap’s robust technical expertise and resources, the company also provides comprehensive server set up and remote hands application installation support. The servers integrate with the CDN to support rich streaming media applications for the Web. Internap provides complete maintenance and management of the servers and also installs the Microsoft Windows Server and Red Hat Linux operating systems upon which customers’ applications are layered.

“Our managed servers give customers a high-quality data center with access to performance IP while helping us to expand our customer and revenue base,” said Tim Sullivan, chief technology officer for Internap. “In conjunction with the new managed server offering, our expertise helps customers launch their businesses faster and get to market quicker at less initial capital expenditure.”

Internap’s managed servers feature redundancy and load balancing in combination with the CDN and MediaConsole® reporting tool. Dedicated firewalls are also available for the servers, which are supported through Internap’s award-winning network operations center (NOC). The scalability of the service allows customers to grow exponentially to field their growing businesses.
