UPDATE 22 May 2012
It looks as though Facebook is now 100% IPv6-enabled, without white-list filtering! See the dig below:

Ahead of the World IPv6 Launch schedule for June 6, 2012, it seems that Facebook has enabled its website www.facebook.com for IPv6. However, here’s the catch: it is only reachable for networks on Google’s White List program (see information on that here: http://www.google.com/intl/en/ipv6/). Don’t believe me? Take a look at some “dig” snapshots from our network (we are on Google’s IPv6 White List) and one from Google’s own public DNS server (8.8.8.8). This is some good stuff! Bring on the rest, but let’s make it totally available to everyone else!
