Last year if you went to AT&T's highest speed tier for Fiber to the corner and copper to the house you received a new residential gateway, Motorola NVG589 which tunneled IPv6 though AT&T uverse network out to the wild. I would say the service at first was not very reliable. Packets were lost, things would stop working and then magically work. Then sometime in May/June a new firmware was pushed to the NVG589 and everything started to work as expected.
Well this Saturday I start to notice web sites taking a longer normal time to load, DNS lookup failing, etc. In my configuration I am running DNSCRYPT over IPv6 to OpenDNS with fallback to a second host under IPv4. When I ran http://testipv6.com it would randomly work. This told me either OpenDNS or AT&T was the root. I then started to ping native IPv6 and was getting about 90% packet loss. Thus the root was IPv6 over AT&T's network again.
I then contacted AT&T's support number and they kept trying to force me to their paid support for PC's, Laptops, and Tablets. Finally I was able to convince them bump me into the queue and for a callback on this. I have yet to receive that callback and have switched everything on my router back to IPv4 and not going back to reduce my headaches. I hope others are having a better experience than I am.
