I just noticed that the quad-A records for both those two hosts are now gone. DNS being what it is, I'm not sure when that happened, but our monitoring system couldn't get the AAAA for www.qwest.com about half an hour ago. Hopefully CenturyLink is actively working towards IPv6-enabling their sites again.

The coming years are going to be difficult enough for end-users without adding unnecessary anti-IPv6 sentiments to the mix. Owen +1 to Owen's comment. I'd also add some more comments: A lot of eyeballs that have v6 right now are the people with a lot of clue. Do you want these people, who'll often be buying or recommending your services to rate your ability to deliver as a fail? Our experience with IPv6 consumer broadband has been that the early adopters are the people who, well, goto IETF meetings, follow standards and ask the bloody hard questions. Even given the Happy Eyeballs (Did Hurricane PAY for it to be abbrievated as HE?? :-) ) most end users prefer IPv6 over IPv4. Deeply this means there is a tendency for v6 traffic to grow and be more important to connectivity than you may imagine. The tipping point for IPv6 traffic being dominant I suspect is going to be a lower threshold of take up than people might expect. Consider this when thinking about the level of thought you give to IPv6 infrastructure and PPS rates. MMC
