WTF? Facebook Login failing

[Wazzerphuk]

Just endlessly cycles round, failing. You have to log out of Facebook to login manually as it continuously tries to do it.

This over HTTP or HTTPS?

Which site? Facebook was https

No matter, I have found the issue. The server is attempting to contact FaceBook over ipv6 and failing, over ipv4 it works. Could be a routing issue or something.
