A Rough Day at Cogent: The Effects of De-Peering

Todd Underwood writes on the Renesys Blog:

These are the signs of the apocalypse: A worldwide earthquake, the sun ceasing to emit visible light, cats and dogs living together in harmony, and Cogent (AS174) depeering another AS. At least one of these happened yesterday.

At about 10:00 UTC on Wednesday (6am EDT), Cogent depeered a number of smaller, UK-based ISPs without notice. This was apparently intentional and due to a review of existing peers and whether they meet peering policies. Does this mean that Cogent is becoming more like its larger competitors that it so enjoys taunting? I'll take a look at who was depeered and speculate on why.
