Just to make something clear.    I do not own any stock, interest or
have any official relationship with Verizon or Cogent.     The
opinions expressed are mine and mine alone as I have come to
understand some of the relationship without the aid of any privileged

Yup, certainly a common thread there.     It wouldn't take a lot of
digging to determine that those "peers" are most likely compensated in
some way shape or form.   Hence the lack of response by the remote
"peer" to upgrade what would most likely be a paid peer.

The term tier 1 is a marketing term.   The last time I looked Cogent
was default free, but certainly not settlement free.    Good luck
peering around a lot of the networks in which they have congestion
from.    The only real way would be to order additional capacity, buy
transit or live with the situation long enough for customers complain
to the remote network.   If that doesn't work then force a partition
with the end objective of Cogent to change from a compensated peer to
a settlement free peer.    It's a fun game, it's unfortunate that
customer flows have to be used to force it.

Let me help translate the canned response.

    We are sorry that we transmit more traffic to Verizon than we are

     We have demanded that the compensated peers be converted to
settlement free peers with greater capacity, with little to no

     Our CEO is aware that this will cost money but is unwilling to
pay for additional bandwidth, so we are in a stalemate and want
customers to complain to Verizon in the hopes that the squeaky wheel
will get the grease or in other terms, free capacity.

    Since the connectivity is compensated, Verizon refuses to provide
additional bandwidth at an acceptable (free) cost.    So, no money
equals no additional customer capacity.

    Our peering folks will continue to pester Verizon's non-commercial
folks by requesting settlement free peers but until enough people
complain to Verizon the requests will fall on deaf ears.
