RE: Cogent?

Cogent is not bad in a lot of places, however, their network in Seattle
is worse than most places though.   They haul almost all traffic to
California for peering (they have only one or two local peers in SEA)
over a non-redundant fiber path (I have a nice snapshot of my BGP feed
sending 400 routes for 8 hours while that fiber was down).

In any case, I think in a multi-homed situation they can fit in nicely,
but these days other providers will provide nicer connectivity for
similar costs.   This of course leaves out the fact that cogent's NOC is
very hard to deal with sometimes, I constantly ran into them wanting
ridiculous amounts of documentation for route additions or any other
changes.   I have limited tolerance for that kind of office-policy since
my other two providers built dynamic filters and were cooperative given
the number of routes we announce (> 100).

On the Seattle Wireless side of things, I was looking at putting some
wifi APs in the windows of the Westin, would anybody be interested in
testing them out?   We would probably charge for access to them, but I
was thinking 802.11g or 802.11a would be pretty slick if I just gave
them each dedicated fastE back to my network.   Anyone up for this?

Good luck sending email from Cogent.  The internet community accuses
them of harboring spammers.  The email blacklists make it difficult to
really do anything useful from their ip space.  

For better or for worse, routing policies force traffic off their
network as fast as possible when its destined for another ISP, instead
of routing it as close as possible internally, and then through the
peering.  This puts more expense on "the other guy", whether their path
is better or not.

Cogent to cogent network traffic has been reported as good.  I have
heard rumors of oversubscription, but all the cogent customers I know
say this is not true.
