New “Green” colocation facility adds 15,000 square-feet of enterprise data center space to support business-criticalweb sites and Internet applications

BOSTON and ATLANTA, February 5, 2009 — Internap Network Services Corporation (NASDAQ: INAP), a global provider of end-to-end Internet business solutions, announced today the availability of 15,000 square feet of new enterprise data center space at 50 Inner Belt Rd. in Somerville, MA. The new space is part of a 45,000 square foot facility offering Internap’s customers ample room for growth.

The new data center, Internap’s second facility in the Boston area, opened with a major anchor customer — Carbonite Inc., whose President, Keith Cooper was on hand to help with the ribbon cutting festivities. Carbonite is a leading provider of online backup services for consumers and small businesses that is enjoying tremendous growth having tripled in both revenue and subscribers over the last year. Also participating in the grand opening event were the Honorable Joseph A. Curtatone, Mayor of the City of Somerville, Internap executives and many of the contractors who worked to build the new data center.

“For Carbonite, our data center is mission critical to the service we deliver for our customers,” said Keith Cooper, president of Carbonite. “We conducted a thorough evaluation of the data center colocation market and found that Internap not only had a premier physical facility with state of the art security, power and network connectivity, but also could handle our rapid growth plans both here and in other geographies. The Internap team is very professional and we have great comfort knowing that we will work well together.”

The 50 Inner Belt facility employs the latest in “green” technology and construction including ultrasonic humidification, air economizers, circuit level power monitoring, white roofing to deflect heat and custom-built cooling systems that ramp up and down based on temperature changes, all designed to provide a less energy intensive solution as compared to previous generations of data centers. During the ribbon cutting, NSTAR, the Massachusetts electric and gas utility, presented an energy efficiency rebate check to Internap for $453,000 in recognition for the green initiatives in the building.

“Internap is investing in the growth of high technology solutions in Boston,” said James P. DeBlasio, president and chief executive officer at Internap. “The quality of our services and our financial strength positions us to be the trusted information technology provider to businesses in the Northeast and around the world. Our expanded data center is a platform for providing IT services with 100 percent reliability to power business-critical web sites and Internet applications.”

Internap’s new Boston data center, one of 45 data center locations around the world, features multi-layered security systems including: closed circuit television surveillance, electronically-controlled card access, multiple biometric scanners, key card readers and facility-issued photo IDs along with 24×7×365 guard staffing.
