www.v6.facebook.com was the official pre-www AAAA record host. I recall a www.ipv6.facebook being added as a redirect because there seemed to be confusion around which one it was. Regardless, to answer the original question, yes www.v6.facebook.com has been official deprecated for almost 2 years now as it was only meant as a test platform for the inevitable www.facebook.com AAAA. If you can not get to www.facebook on v6, please work with your ISP to find out why. When I left there, it was still a whitelisting design for known good networks, but I believe that was done away with after this years ipv6 day. -Will Lawton On Oct 25, 2012, at 9:17, "Jima" <nanog@jima.tk> wrote:

Since Wednesday at 1:48 pm Central www.ipv6.facebook.com has not been loading (though it's pingable). Does anyone know if this has been formally deprecated?

As I recall, the primary IPv6-only FQDN was (and still is) www.v6.facebook.com . I honestly never noticed that they added an AAAA for www.ipv6.facebook.com .

Hardly scientific, but http://www.googlefight.com/index.php?lang=en_GB&word1=www.v6.facebook.com&word2=www.ipv6.facebook.com seems to support my memory to some degree.
