Internap’s continued data center expansion in company-controlled markets allows customers to expand their footprints and take advantage of increased power density capabilities

ATLANTA – November 4, 2010 —Internap Network Services Corporation (NASDAQ: INAP), a leading provider of end-to-end Internet business products and services,today announced the expansion of one of its Boston-area data centers. The expansion at 50 Inner Belt in Somerville, Mass. will include approximately 7,000 square feet of net sellable raised floor space. This is the second of Internap’s three planned expansions in this facility. The announcement comes 18 months after Internap initially opened the data center.

The data center expansion is planned to be online in the second quarter of 2011. The new space will have expanded power density capacities of up to 10 kilowatts per rack. Internap’s data center at 50 Inner Belt is supported by a power sub-station on the property. The higher power density capacity will make the data center one of the more robust sites in the region.

With the addition of Boston, Internap will bring a total of approximately 36,500 square feet of additional net sellable space to market within a year.
