I've had Comcasst IPv6 for the last few years, none of the issues I've encountered with IPv6 were Comcast's fault. What sort of problems did you encounter?

  I have a Comcast business account. I've had an IPv6 address for a few years, and generally, it has worked exactly as expected. I've had two outages that are notable: 1. an outage where v6 traffic was just dropped, period. It took a service call, but was fixed within a day, IIRC. It was no more or less painful than any other service call. 2. an outage where v4 TCP SYNs were dropped, mostly; once a connection was established, the connection was fine. AFAICT, this was some issue, perhaps HW failure, with their modem/router combo. Once the router was replaced, the issue was fixed. This took several days to correct, mostly because it was difficult to convince Comcast's techs that the physical copper cable is probably not discriminating against IPv4 traffic. My experience w/ their business division is that the support agents have some light experience. My experience w/ their residential side is that the support agents have never seen a computer. The rollout to business was after the rollout to residential; I also filled out a form requesting one way back in the day when they were essentially polling for interest.

I'm torn between laughter and intense anguish. I'm afraid to even estimate how many days of my life have been spent honing my rhetorical skills to convince a support agent of similar points.
