<font face="Arial">Hi,<br>
<br>
I'm trying to figure out if this is my problem or a Facebook problem.
The first issue was with facebookmail.com. The cache entry would
become corrupt and I would have to clear cache to get things back to
working again. Since facebookmail.com resolves to a single IP address,
my work around was to make my internal DNS authoritative for it and the
problem went away.<br>
<br>
A week ago, DNS lookups for facebook.com failed completely. Even
restarting the DNS service didn't fix the problem. Currently, and as
a temporary fix only, I am forwarding facebook,com lookups to an
off-campus server which does not seem to have the problem. And now, as
of last night, lookups to fbcdn.net (which apparently hosts
stylesheets) fail completely and I've implemented the same forwarding
scheme there as well. I've been tracking resource allocations on the
Linux box that hosts the DNS just to see if there might be some
connection there, and as far as I can tell, there isn't anything there
that might explain it.<br>
<br>
Being that we are a four year residential college, the heaviest hit on
our DNS servers are students, and Facebook is the singularly most
heavily used external service. Also, as far as I can tell, we are
having no problems looking up any other addresses. Has anyone else
seen this problem with Facebook or does this problem sound familiar
with any other sites. I'm baffled and any ideas about what to look for
would be most appreciatd.<br>
<br>
Thanks,<br>
