Cogent Communications operates C.ROOT-SERVERS.NET as a public service to the Internet. First operational in 1987, C.ROOT-SERVERS.NET was known as C.NYSER.NET and was established at the request of the Internet Assigned Numbers Authority (IANA). In 1994, C.NYSER.NET became C.PSI.NET. PSINet, the first commercial ISP ever established, was operating the server when the root nameserver system started using the root-servers.net domain and thus became C.ROOT-SERVERS.NET. In 2002, Cogent Communications acquired PSINet's major U.S assets, which included responsibility for operation of C.ROOT-SERVERS.NET. To promote the vital development of global social and economic infrastructure, Cogent Communications has committed to the safe, reliable and secure operation of the root server for the benefit of the entire Internet. Instances of C.ROOT-SERVERS.NET are located in several locations throughout the United States and will be installed in Europe as well.
