This is my bet. Let's see. Peering went down October 6th. Then a fedexed
letter with nasty threats arrives today [with a fax copy arriving on the
6th]. Then a letter from Level3 fedexed back on the 7th for delivery on
the 9th saying "We've cured the default and here is 30 days notice that
we are terminating your account or changing your service."
Then 30 days from the 10th to November 9th...
Yup. Sounds about right.
Dave (I'm merging your comment in here too):
One question [referring to customers being used as pawns] -- what does
ANY network have besides their customers to use in a peering negotiation?
Engineers often try to use things like prefix counts, # of routers, # of
countries, blah blah blah but really these are all oblique references to
the size and import of the single homed customers behind that network.
Level3 thought their customers were more desirable than Cogent's.
Level3's customers seem to have enough respect for Cogent's customers to
make Level3 blink. I seem to remember the same thing happening with
[another network] trying to depeer Cogent a few months back.
What I find interesting is that in this case, Cogent apparently allowed
the sessions (whichever ones Level3 decided to fire back up) to come up
cleanly. I think in that earlier instance Cogent kept the peering
sessions down until some point [one speculates until the legal paperwork
came through] -- notice I said "I think" I have no specific facts, just
a vague recollection.
Taking this back to pricing (I suddenly found about 30 minutes I didn't
expect to have), if Cogent terminated their most recent $6/mb/s or
$8/mb/s promotion because of this concern with the Level3 peering and
Level3 does indeed blink [comes back to the table and agrees to an
indefinite term of SFI] Cogent might re-establish the promotion and with
it grow by another 20 or 30 Gb/s or more.. possibly at the direct
expense of Level3 and others and force more growth of their
interconnections.
Another question (wow, 3 or 4 separate threads in one email). Instead of
a "hard" de-peering. Wouldn't it be more effective if Level3 just
stopped adding interconnection capacity to Cogent? That is an effective
way of limiting the growth of losses between two networks, and if some
discreet situation can be used [say a balanced traffic ratio] no new
capacity will be added until that situation is resolved? Cogent [in
this case] could solve the problem by adding the appropriate # and type
of customers or by buying transit to add capacity [and possibly
forfeiting SFI]. Then instead of using your peering partner's customers
as pawns, you are using your own to drive the business case either way.
That is a much "nicer" way to put pressure on a peer without it getting
blasted all over the headlines... Especially if you are the network
doing the depeering. And if your customer contracts don't cover
(SLA-wise) interconnections, you don't care either way.
Just a few ideas...
