UltraDNS Expands Operations

East Coast Presence Will Better Facilitate the Company's Sustained Growth

SAN MATEO, Calif., July 23, 2003 -- UltraDNS™ Corporation, the world's leading Managed DNS Service Provider, today announced the opening of a new office in Northern Virginia.

"With over 7,500 customers, the expansion to the East Coast is a result of the increased demand for UltraDNS services worldwide," said Ben Petro, president and CEO, UltraDNS. "This growth will enable the company to further propagate robust and reliable DNS technology to our customer base and provide secure infrastructure services to the federal government."

Over the past four years, UltraDNS has established itself as the most secure DNS provider in the world. The company strategically chose the Washington DC metropolitan area in order to better acquire and support agencies within the federal government, whose primary focus is network security and reliability. UltraDNS maintains significant network facilities in the Washington DC metropolitan area.

The new office will strengthen UltraDNS' business by allowing direct, personal contact with its customer base. Maintaining a larger East Coast presence will also significantly shorten sales cycles with both government and local commercial organizations. Members of the UltraDNS operations, sales and finance divisions will operate from the Virginia office to streamline customer deployment and network management.

"Our Northern Virginia presence provides increased access to networking customers and immerses UltraDNS in a rich competitive environment," said David Novosad, vice president of operations, UltraDNS. "The company will continue to broaden its footprint and services to capitalize on new business opportunities."

The new office is located at 11720 Sunrise Valley Drive, Suite 401, Reston, VA 20191.
