WASHINGTON, D.C., June 17, 2002 - Cogent Communications Group, Inc. (AMEX: COI), a Tier One, next generation, optical Internet service provider, announced today that C-SPAN has selected Cogent to provide a point-to-point, high bandwidth connection that is enabling an innovative, two-way, distance learning program for students at the University of Denver.

Over Cogent's 100 Mbps dedicated transport connection, C-SPAN's distance learning program is taught by Dr. John Splaine, an award-winning professor who has taught at the University of Maryland's School of Education for 32 years. Dr. Splaine develops and teaches accredited courses to DU students based at the Distance Learning Studio of The Cable Center, which is adjacent to the DU campus. By conducting the course from Washington, D.C., Dr. Splaine is able to invite elected officials, national journalists and policy experts as speakers. He has access to C-SPAN's on-location field cameras, as they cover unfolding events, and to C-SPAN's archives containing thousands of hours of political programming.

Cogent was selected for its cost-effectiveness, its reliability and quality of service. "Cogent's dedicated bandwidth and ring architecture provided C-SPAN with a level of comfort that no other ISP could match. Knowing that the bandwidth would be there all the time and that the transmission could not be interrupted - even if there was a fiber cut - was a big factor in selecting Cogent to provide the point-to-point connection," said Barry Katz, C-SPAN's Video Assets Manager.

Cogent's all optical network is layer 3 protected and built in a series of physical rings both on the longhaul backbone and in the metro areas. These two aspects combine to allow the routers to detect if there is a fiber cut, then redirect data around the ring in the other direction, restoring the data transmission in less than a second.

"C-SPAN is an excellent example of how Cogent's unique architecture and unlimited bandwidth enable customers to push the envelope on new bandwidth applications," said Dave Schaeffer, CEO Cogent Communications. "It is my prediction that distance learning will rapidly catch on at educational institutions across America once bandwidth and connectivity constraints are lifted. Through C-SPAN, students at DU now have the wonderful opportunity to be exposed to a higher quality and a more diverse range of experts than previously imagined and Cogent is glad to be a part of making this happen."

The first semester was successfully completed May 30th, 2002 and will resume in the fall. The semester ran without any complications or connectivity issues. Cogent's uninterrupted transmission also allowed cost-effective video and data communications between Dr. Splaine and his students outside of regular class hours.
