SAS 70 Type II Audit Enhances Internap’s Premium Data Center Offering

Third-party audit confirms Internap’s commitment to operational excellence at company-controlled data centers including flagship facilities in Boston and New York City

ATLANTA, December 3, 2009 — Internap Network Services Corporation (NASDAQ: INAP), a global provider of end-to-end Internet business solutions, today announced it has successfully completed the Statement on Auditing Standards No. 70 (SAS 70) Type II audit for its company-controlled data centers. This activity is part of a continued commitment by Internap to provide advanced services to IT professionals interested in facilities that have demonstrated capabilities against the highest standards for service delivery. The audit included the more than 491,500 gross square-foot of data center space at 50 Inner Belt Road in Somerville, Massachusetts, and 111 8th Avenue in New York City, as well as six additional facilities in Atlanta, Houston, and Seattle.

The SAS 70 Type II audit confirms that Internap’s data center security and operational procedures have been reviewed and tested by an independent certified public accounting firm to validate that controls and processes have been suitably designed and are operating effectively to protect and safeguard customers’ equipment and data. Internap chose to undertake the more stringent Type II audit and it confirms that only authorized Internap employees and customers are granted access to the data center, redundant HVAC and UPS systems reduce the likelihood that mechanical and electrical failures will result in an outage, and all critical facility systems – smoke detection, cooling and power – are inspected and serviced regularly and monitored continuously to ensure effective operation.

Internap’s SAS 70 Type II audit is the culmination of considerable time, energy and resources the company has invested in expanding its footprint in the Boston and New York markets over the past year. In February 2009, Internap opened 50 Inner Belt, a 45,000 gross square-foot, state-of-the-art facility. In April 2009, Internap completed an expansion and upgrade of its 76,000 gross square-foot data center at 111 8th Avenue. Both were ‘green build’ projects featuring the industry’s newest and most energy-efficient data center systems.

“Internap provides its customers with superior levels of security and reliability in a world-class data center environment, which is especially critical for businesses dealing with Sarbanes-Oxley, HIPAA, PCI and other industry or governmental compliance requirements,” said Michael Higgins, Senior Vice President of Data Center Services, Internap. “By achieving and maintaining the SAS 70 certification, Internap provides customers – particularly those in financial services, pharmaceutical or healthcare industries – the added validation they demand from a premier data center provider.”

Established by the American Institute of Certified Public Accountants, SAS 70 is a widely-recognized auditing standard. It allows third-party service auditors to fairly and objectively assess the operational effectiveness of the relevant internal controls of a service organization such as Internap.
