IPv6 version of www.qwest.com/www.centurylink.com has been down for 10 days

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

Hopefully CenturyLink is actively working towards IPv6-enabling their sites

FYI, the issue is not resolved and I've not heard from either of the
companies suggesting that they're working on it.

Note their commitment to IPv6 in these releases:

It'd really suck for end users to start actively avoiding IPv6 connectivity

+1 -- I'm all for publishing AAAA records as everyone knows, but, if you
publish AAAA records for a consumer facing service, please support and
monitor that service with a similar level to what you do for your IPv4
versions of the service.

The coming years are going to be difficult enough for end-users without
adding unnecessary anti-IPv6 sentiments to the mix.


+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

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.
