Facebook supports ipv6, but maybe it is external only? I know Google is ipv6 internally too. Although as EC2 has no ipv6 maybe that was the blocking issue.

  Facebook makes extensive use of IPv6 internally. As you suggested, EC2's lack of support is the issue. Edit: here are the slides from Facebook's presentation to the IPv6 World Congress in March about their internal IPv6 use. If IPv6 interests you, they're definitely worth a read: http://www.internetsociety.org/deploy360/wp-content/uploads/2014/04/WorldIPv6Congress-IPv6_LH-v2.pdf http://www.internetsociety.org/deploy360/wp-content/uploads/...

    Thumbs up for the interesting read. It's amazing how Amazon doesn't support IPv6 yet, though

  You can reach Facebook over IPv6 at https://www.v6.facebook.com https://www.v6.facebook.com Interestingly enough, last week when they had their 45 minute outage worldwide with some kind of routing problem, it was still up and running on that address

    Facebook has AAAA records on the main https://facebook.com https://facebook.com domain, so you don't need the v6 part anymore.

      And the IPv6 address ends face:b00c:0:1 - hat tip to them.
