Some things just never change at cogent.. fought them for months way 
back when to get me off their infamous 2 bgp peer setup after many an 
outage due to this setup, they finally put us on a single bgp session 
but it took forever. Lets just say cogent didn't last long at the 
company I worked for.

  You get what you pay for....
