WASHINGTON, D.C. July 26, 2013 – Cogent Communications Group, Inc. (NASDAQ: CCOI), one of the largest Internet service providers in the world, today announced the resignation of Erel N. Margalit from its Board of Directors. Mr. Margalit started Jerusalem Venture Partners in 1998 and was a founding investor in Cogent. Mr. Margalit was recently elected to the Israeli Parliament and is vacating his Board position in order to devote his full time and attention to his public service obligations.

"I would like to express my deep admiration and respect to CEO and founder Dave Schaeffer and his management team for bringing the company to where it stands today - one of the world's largest and most prominent Internet Service Providers," said Margalit. "Thirteen years ago, when Dave and I first envisioned what Cogent could become, we never anticipated the focal position it would take in the transport of the world's video and Internet traffic. I am proud to be a founding investor who believed in the team and its vision."

Mr. Margalit's resignation will be effective immediately, and the entire Cogent team and fellow Board members wish him well as he devotes his full attention to his service in the Israeli Parliament. "Cogent's growth and success as one of the core carriers of Internet traffic is largely due to the guidance and support of early partners like Erel," said CEO Dave Schaeffer. "We respect his dedication to public service and know the same vision, focus, and enthusiasm he provided to Cogent will serve him well in this new role."
