Cogent now peering with Sprint?

I never thought Sprint would ever renew its relationship with Sprint:

Next I will see pigs flying :slight_smile: Wonder how long it will last based on
Cogent's past behavior as noted here.

I've not watched here closely for a number of years, but I now have a Sprint connected customer who is hating life and Cogent seems to be part of the equation. Can someone fill me in on the history of their relationship?

neal, all,

I've not watched here closely for a number of years, but I now have a
Sprint connected customer who is hating life and Cogent seems to be part
of the equation. Can someone fill me in on the history of their
relationship?

they used not to peer and cogent reached sprint via ntt america
(verio). now they are directly connected (at least in north america
for north american routes).

the routing situation is evolving and may have changed since last i
wrote about it at:

http://www.renesys.com/blog/2006/11/sprint_and_cogent_peer.shtml

(there's some path detail in that posting including stuff about when
the most recent change took place and what kind of prefixes are
carried on the adjacency. there's nothing in there about the quality
of either network or the capacity of the interconnection).
