Hi Mark, Thanks for responding / confirming. My transits that are C&W peers are Telus and 306/GT. I contacted them to contact you as I am not a direct C&W customer. I am just in the middle so to speak trying to understand and work around the problem. ---Mike At 06:38 PM 09/03/2004, Mark Kasten wrote:
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 noc@cw.net. I don't see any emails from you sent to noc@cw.net.
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
