ATLANTA, GA. – October 1, 2008 – Internap Network Services Corporation (NASDAQ: INAP), a global provider of end-to-end Internet business solutions, today announced it has expanded its relationship with NADAguides.com, a leading vehicle pricing and information website. NADAguides.com now relies on Internap for the company's CDN, data center colocation and Performance IP™ networking services. This extension of Internap products was prompted by the expansion of the vehicle information and services offered at NADAguides.com, as well as the growth of NADAguides.com traffic to approximately six million visitors and more than 60 million page views each month.

Launched in 2000, NADAguides.com is the world's largest publisher of vehicle pricing and specification information. The site covers new and used cars, trucks, vans and SUVs, as well as classic, collectible, exotic and special interest vehicles, van conversions, limousines, RVs, motorcycles, boats, ATVs, personal watercraft, snowmobiles and manufactured housing.

Since its launch, NADAguides.com has expanded its offerings to include: side-by-side new and used car comparisons; new car prices, specifications, photos and 360-degree views; new car building and pricing tools; dealer price quotes; car reviews, previews and event information; incentives and rebates information; five-year cost of ownership data; safety and owner ratings; video buying guides and test drive videos; new car fast facts; finance and insurance services; vehicle history reports; credit check information; payment calculators and more.

"Not only have we expanded the information, tools and services we offer at NADAguides.com, the number of people coming to our website and the amount of information they access has grown as well," said Shervin Farivar, chief technology officer at NADAguides.com. "With Internap, we did our homework and found an end-to-end technology solution to deliver our information with 100% reliability. It is this reliability that ensures NADAguides.com visitors have the best online user experience possible – all the time, every time."

Unique to the industry, Internap delivers an integrated solution of CDN, data center colocation, application hosting and IP networking. This solution set is based on Internap's patented network optimization platform known as MIRO (Managed Internet Routing Optimizer™), as well as a global infrastructure of private network access points (P-NAPs). The result is high-traffic websites, such as NADAguides.com, run with 100% reliability, scale up automatically to meet demand spikes and easily support the use of rich media, including video, audio and graphics applications.

"Millions of people turn to NADAguides.com for its broad range of vehicle and information and services," said Tim Sullivan, chief technology officer at Internap.
