Facebook's "profile.ak.fbcdn.net" does not resolve correctly

[James O'Donnell]

I have been having problems loading my facebook profile at home, and
finally uncovered that it has to do with the DNS lookup. When I
switch back to my ADSL provider, the profile pictures load correctly,
with Google DNS they do not. The IP addresses look very different for
Google DNS.

I'm having the same problem. Facebook does not load a majority of the
time... so I have to switch back to opendns just for this.
