Actually, where I have mostly seen the biggest problems with the Cogent =
remote BGP
hacks is when their forwarding decisions in between your router and =
their BGP
speaking router don=E2=80=99t actually deliver your packets to the BGP =
speaking router
and your traffic starts veering wildly off course to god knows where.
Likely they=E2=80=99ve gotten better at avoiding this over the years, =
but there were times
when it resulted in very interesting loops and very strange paths that =
often
did not ever reach the intended destination.
Worse, when you encountered one of these hairballs, finding someone at =
AS174 with
enough clue to understand your traceroutes let alone fix anything was an =
additional
challenge.
