Re: BellNexxia to C&W problems in NY ? (AS577 - AS3561)
- From: Mark Kasten
- Date: Tue Mar 09 18:41:27 2004
Mike,
It does appear that this interconnect is running a bit hot. If
there is anyone from Bell Nexxia/AS577 listening, feel free to ping me
offline and I'll see what I can do to help out. But, to be honest, this
is an issue that could/should be handled your upstream and [email protected]
I don't see any emails from you sent to [email protected]
Regards,
Mark Kasten

I have a few users exchanging data with sites inside Bell Canada call
in to complain today with various symptoms (eg. VPNs timing out,
transfers taking a long time). After a bit of narrowing down, it
would seem that when the traffic comes at me via C&W from Bell (2 of
my 3 transit providers 852 and 6539 talk to parts of Bell this way)
the problems are acute.
Looking at traceroutes between C&W and Bell IP space, there does
indeed seem to be some issue between their exchange point in NY
