Internap Readies P-NAP Architecture For Next Wave Of IP Connectivity Growth; Key Markets to Undergo Capacity Upgrades to Serve

Internap Network Services Corporation (AMEX:IIP), a
leading provider of performance-based routing solutions over the
Internet, today announced that it will upgrade eleven of its Private
Network Access Point (P-NAP) locations to address customer's growing
capacity needs in key markets. In addition to the recent completion of
its first 10 Gigabit (10G) based P-NAP(R) re-architecture in San Jose,
additional upgrades are targeted in Atlanta, Chicago, Dallas, London,
Los Angeles, Miami, New York, San Francisco, Seattle and Washington
DC.
   A key market differentiator, the Internap(R) P-NAP infrastructure
is central to its ability to offer reliable connectivity across the
entire Internet, as opposed to just one network. Inside each P-NAP
resides the company's proprietary route control software, which
continuously monitors and redirects customer traffic across up to
eight major backbones to optimize performance. As a result, Internap
is able to offer 100% uptime and overcome various problems that may
halt or degrade the performance of real-time Internet applications.
   "Building upon our market-leading IP network with speed and
flawless execution is a vital step in meeting growing customer
demands," said James P. DeBlasio, chief executive officer, Internap.
"We believe that now is the time to improve our infrastructure while
positioning Internap to reach a new level of performance and maximize
our return in multiple markets."
   During the first quarter of this year, Internap experienced
continued acceleration in customer traffic growth. With quarter over
quarter traffic growth of 25% and evidence of continued demand,
Internap believes that now is the time to prepare for even faster
growth. The P-NAP operational investments will add significant scale
to the Internap network. The plan will increase each P-NAP's total
capacity and, in some cases, more than triple existing capacity while
providing a modular approach to expansion. Implementation is expected
to span through the third quarter with a staggered schedule of markets
coming on-line through the remainder of the year.
   To enhance its reliability and uptime guarantee, Internap also
maintains industry-leading SLAs that cover customer traffic from
end-to-end. The IP offering protects customer traffic from
unpredictable issues that may prevent the delivery of data across the
Internet, such as network congestion, outages or human error. Internap
also provides proactive technical support through a best-in-class
Network Operations Center (NOC) that manages customer traffic
24x7x365.
