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?

I am getting NXDOMAIN for www.ipv6.facebook.com thus it likely is fully
gone now:

www.facebook.com is nicely at 2a03:2880:2050:1f01:face:b00c:: (which is
kinda scary as typically the lowest address is a subnet anycast address,
but I guess they have just configured it as a /128 and then it is not an
issue...)

Same from here.

www.facebook.com is nicely at 2a03:2880:2050:1f01:face:b00c:: (which is

kinda scary as typically the lowest address is a subnet anycast address,
but I guess they have just configured it as a /128 and then it is not an
issue...)

The lowest address on that subnet (presuming a /64) would be
2a03:2880:2050:1f01::

Interresting, I was just now getting responses pointing www.facebook.com
to (long live infinite scrollback):

and then finally:

www.facebook.com. 120 IN AAAA 2a03:2880:2050:1f01:face:b00c::

Note that is 2110 != 2050.

But now indeed to the c10r one... thus there are at least a couple of
clusters it seems.

I found this to be rather amusing.

Right.

I'm in ASEAN, FWIW.

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.

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.

Yes, www.v6.facebook.com has been deprecated.
The dual-stacked www.facebook.com (via World IPv6 Launch) is the way to go,
until we run out of addresses again.

Thanks and cheers
