Yes, they are indeed there on the server. It makes no sense to me how they
can be, while not being on the server. I find it hard to believe myself.

It's running on Amazon EC2, so who knows. But now that I think of it I
should probably take it up with them, maybe that's where the issue really
is. But since there's no IPv6 support on Amazon, we should probably just
disable it altogether and that might take care of the issue.
