Network services provider Cogent experienced network outages this morning, which reportedly caused broader availability problems for web sites and networks that rely on Cogent for connectivity. Traffic on major backbones appears to have returned to normal.
Cogent's network spans 29,500 miles of fiber and connects with 1,750 networks in major U.S. markets. Our monitoring of Cogent's business web site (cogentco.com) shows a brief outage this morning:
A dynamically updating chart of Cogent's web site performance is available. Netcraft offers a web site performance monitoring service that provides similar charts, along with e-mail alerts when an outage occurs.
