Cogent Communications is a multinational internet service provider whose network spans more than 30,000 miles and provides service in over 100 cities across 20+ countries. Cogent carries more than 11 petabytes per day of Internet traffic and connects to approximately 2,300 networks, including 330 peer ASes. Cogent believes it has grown to become the second largest carrier of Internet traffic in the world with over 17% of the world's Internet traffic crossing its network.

Cogent has been controversial in the ISP market for its low, $10-per-megabit pricing and its public disputes over peering with AOL (2003) [1], France Telecom (2006)[2], Level 3 (2005)[3] and TeliaSonera (March 2008). [1]. Cogent states that they are a strong supporter of an open and free peering policy and that they treat all data on their network equally with the highest level of priority possible.[4]

Cogent's AS174, has one of the highest-ranked connectivity degrees on the Internet.[5][6]

[edit] Acquisition History

Cogent was founded in 1999 at the peak of the height of Industry growth. Soon thereafter, vast market wealth was eradicated with the telecom bubble burst and many other ISPs were thrown into a state of turmoil. Over three brief years, Cogent completed 13 acquisitions of other failing providers. Whether it was an entire company or just select assets, Cogent was able to acquire over $14 billion of invested capital through these acquisitions which it purchased for only $60 million, including $4 billion worth of Power, Plant and Equipment.[7] See Cogent's acquisition history below:

On March 14, 2008, after Cogent stopped routing packets from European network provider Telia (AS 1299), their two networks lost mutual connectivity.[citation needed] The connection was reestablished March 28, 2008 with interconnection points in both the United States and Europe.[citation needed]
