Two IPv6 websites down

Tue Nov 3 04:35:19 UTC 2015

Without disclosing too much, I learned from a person within BT's broader
organization that the removal of AAAA for www.bt.com was intentional for
troubleshooting purposes.

My regular BT and CTL link contacts have not responded, but perhaps there's
another engineer on the list that can investigate.

www.bt.com hasn't had an AAAA since Friday, October 30 at 4:36 am (U.S.
Central).  OpenDNS carried it for a while longer yesterday, but when I
checked this morning it was gone.

www.centurylink.com (and www.qwest.com) have had HTTPv6 access down since
Friday, October 30 at 1:21 am (U.S. Central).  I suspect that after
maintenance something wasn't fixed up or restored.

In addition, the following sites, which had working HTTPv6 at one time,
remain down:
enterprise.ca
cs.co
mydeviceinfo.comcast.net
www.dnssec.comcast.net
wireless.att.com
www.att.net (Akamai hosted)
www.charter.com
www.twtelecom.com

Frank
