Cogent Acquires Carrier1 Network Assets in Germany

WASHINGTON, D.C., March 31, 2004 - Cogent Communications Group, Inc. (AMEX: COI), a multinational Tier One, optical Internet service provider, announced today that it has acquired rights to the dark fiber and other network assets that were once part of Carrier1 International S.A., through a merger with Symposium Omega, Inc., which had raised $19.5 million from investors and acquired rights to this network. Symposium Omega acquired the network from GLH GmbH, a German company that purchased the assets directly from Carrier1 after Carrier1 filed for insolvency in Germany. As a result of the acquisition, Cogent will add 14 German markets to its Pan-European network including, Berlin, Hamburg, Frankfurt and Munich, making Cogent's one of the largest network footprints in the region.

"The Carrier1 network is a perfect complement to our acquisitions of LambdaNet France and LambdaNet Spain that took place in January," said Dave Schaeffer, CEO Cogent Communications. "Now that our footprint is essentially complete in Europe, we will focus all our energy on capturing market share with our compelling combination of high quality data transit and transport services at prices that no other provider can match."

"To date, we have been very effective in picking up assets and customers at pennies on the dollar, and the Carrier1 acquisition is no exception," said Helen Lee, Cogent's Chief Financial Officer. "Our ability to attract new customers based on our price points and quality of service has added maximum value to the assets we acquire."

Cogent has already connected LambdaNet France and Spain to its U.S. based network and is completing the consolidation of all traffic to one Autonomous System number. U.S. customers have already been consolidated to AS174. Consolidation to one AS means no network hops for Internet traffic traveling anywhere on the Cogent network whether it is European- or American-bound.

Over the next few weeks, Cogent plans to finalize and launch its complete European product set on its website located at www.cogentco.com.
