Acquisition History

Although debuting at the height of the telecom industry, Cogent soon found vast market wealth eradicated and many other ISPs thrown into a state of turmoil. In a survival of the fittest competition, Cogent became the consolidator in a consolidating market. Over three brief years, Cogent completed 13 acquisitions of other flailing providers. Whether it was an entire company or just select assets, Cogent was able to acquire valuable network assets, customers, peering relationships and building access agreements for pennies on the dollar.

Among Cogent's 13 acquisitions to date include three of the original generation Internet Service Providers who were pioneers in the late 1980s and early 1990s. These companies—PSINet (originally Performance Systems International), NetRail and Aleron (originally AGIS/Net99)—were the earliest providers of commercial Internet service.

Other strategic acquisitions include assets from: Allied Riser, OnSite Access, Fiber City, Fiber Network Solutions, Applied Theory, LambdaNet France and Spain, Carrier1, Unlimited Fiber Optics, Global Access, Aleron, NTT/Verio.
