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.

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 Regards, Frank root@nagios:/home/fbulk# wget -6 www.centurylink.com --2015-10-31 09:53:13-- http://www.centurylink.com/ Resolving www.centurylink.com... 2001:428:b21:1::20 Connecting to www.centurylink.com|2001:428:b21:1::20|:80... failed: Connection timed out.
