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

(there's some path detail in that posting including stuff about when
the most recent change took place and what kind of prefixes are
