Cogent Gets High Marks From University Market

WASHINGTON, D.C., December 3, 2004 - Cogent Communications Group, Inc. (AMEX: COI), one of the fastest growing Internet service providers in the industry, announced today that its combination of price, quality and customer service has attracted some of the top higher educational institutions in America to sign for Cogent's ultra-high bandwidth Internet service.

In reviewing data from the 2005 U.S. News & World Report "America's Best Colleges and Graduate Schools, Cogent provides bandwidth to:

Half of the Top 100 America's Best Colleges,

More than half of the Top 50 Business Schools, and

More than half of the Top 50 Law Schools

"Cogent is committed to providing educational programs with the highest quality and most competitively priced service available in the market today. It would be hard for universities to find Tier 1 dedicated Internet service for less then the $10 per megabit of dedicated, non-oversubscribed Internet access that Cogent currently offers," said Andrew Hathaway, VP of Wholesale Services at Cogent.

A key factor in Cogent's successful penetration of the university market has been its relationship with regional organizations such as SURA (Southeastern Universities Research Association), which fosters collaboration on IT initiatives among over 60 universities located throughout the southeastern United States.

"SURA has found a great deal of value in Cogent's Internet service," said Gary Crane, Director of IT Initiatives. "Cogent's price-point has enabled SURA to coordinate a large amount of bandwidth at a very low price, providing a significant benefit to our participating members."

"We have seen customer bandwidth growth, particularly at the college level, growing between 100% and 300% per annum. This dynamic growth rate becomes an issue for universities trying to remain within a budget," said Dave Schaeffer, CEO Cogent Communications. "Cogent's philosophy of providing large amounts of bandwidth at cost-effective, flat rate pricing provides the perfect solution for Universities looking to meet bandwidth demand and remain within budget."

Cogent continues to work with individual universities, school districts and research institutions as well as large regional organizations like SURA to provide millions of students with ultra high speed bandwidth to meet the needs of the Net-Ready Generation.
