Here’s what’s happening – comcast is routing all of our traffic, regardless of where we’re navigating to, through Nashville, then Chicago, ATL, Dallas, LA, and then to whatever the destination is. This means, for instance, that when we ping facebook.com, the traffic has to travel more than 11,000 miles. As it is now, we start seeing significant packet loss at 11 hops or so. Unfortunately, there’s apparently no one at comcast that you can reach via phone who understands how route tables work. This is a widespread problem in our area (Smyrna, TN), and comcast’s standard response is to ping the modem, say ‘oh, I see what you’re talking about’, and then schedule someone to come check your modem and wiring. Even when I explain to them that they need to let someone in the NOC know about it, since the problem doesn’t even occur until the traffic is 1,000+ miles away from me, the next question I usually get is “are you using a wireless modem?” How thick can you get?
Any ideas on how to get these folks to figure out that the problem may actually not be with my wiring?? If there was an alternative for high speed Internet in my market, I’d be on it instantly, and so would me clients.
Please post some sample traces to the sites that you feel are being mis-routed.
Yes.. I have spent 12 hrs on the phone w/ comcast (tm) relative to my intermittent problems with TCP/IP connectivity over the last 6 weeks. Routing from HSV to ATL was fine, but tracrt failes via Nashvile would fail. This would be every time I was trying to connect to Netflix.
