Is anyone else in the Boston area seeing any IPv6 packet loss on Comcast tonight? IPv4 shows no packet loss at all, but IPv6 is losing 10-20%. It looks like the problem is inside Comcast. I tried reporting this to them, but all they want to do is replace my cable modem with one that isn't "end of life" (which when I asked why they never told me this they replied that "notices will go out very soon now") or charge me $39.95 to roll a truck. It would be good to know if others in the Boston area see the same packet loss. Thanks. Comcast to WPI: gauge (::) Wed Sep 9 01:30:48 2015 Resolver: Received error response 2.
