WASHINGTON, D.C., March 6, 2007 - Cogent Communications Group, Inc. (NASDAQ-CCOI) announced today that Photobucket has doubled its bandwidth connections with Cogent. Photobucket, the online personal media company where over 37 million people create, manage and share their personal digital media, continues to experience explosive growth. The site is adding over 85,000 new users each day, which is resulting in significantly increased IP traffic demands.

Cogent has been Photobucket's primary provider of Internet bandwidth since 2005 and continues to support Photobucket's goal of reliable performance and uptime for their users. Part of that experience is making sure there is always enough capacity to handle traffic growth. This has resulted in several capacity upgrades for Photobucket and Cogent over the years, to keep in line with this continued user growth.

"We turned to Cogent for their pricing, we stay with Cogent for the quality and performance of their network combined with their superior customer support," said Darren Crystal, CTO and Co-Founder of Photobucket. "Our users are the trendsetters when it comes to social media – their demands continue to grow as they upload more images, videos and remixed content. We are relying on Cogent to help us keep pace with the resulting bandwidth demand."

"Social networking is on the rise and so is the popularity of integrating media formats such as photos, graphics and video which all drive increased demand for bandwidth. Cogent is perfectly positioned to handle this bandwidth explosion by having ample capacity at the most attractive pricing in the industry," said Dave Schaeffer, CEO Cogent Communications. "Photobucket exemplifies how Web applications are able to advance and keep pace with user demands, with the availability of more and more bandwidth."

Photobucket is the Web's largest personal media site, with more than 37 million users. Photobucket's users store their photos, videos, remixes and images on Photobucket, and link from Photobucket to all their online profiles, personal Web sites and blogs. It serves over one billion content calls a day to the MySpace community alone. In the January 2007 ComScore rankings, Photobucket is the #6 most popular entertainment site in the US, and #35 most popular Web site overall.
