Could it be a dns issue? Some sites trying to resolve your ip address
and others don't?

Can't find my IP on any of the black lists. Don't have any proxies.
Sites
that behave poorly are consistent. That is to say that facebook.com,
apple.com would always come up without an issue, but cnn.com,
forever21.com(i know, don't ask, students),
store.apple.com would consistently take forever to come up.
Just wanted to check of rate-limiting web clients is a common practice
nowdays in the industry. If it's not, it's probably an unlikely
cause of my
troubles...
Thanks,

Hi list
I have a problem that I can't seem to find a solution to yet. My
student
network is being NATted out and anyone who's on that network had
troubles
accessing random websites.
For example, going to www.apple.com or www.facebook.com would work
great,
but store.apple.com would either not load or take forever to open
up.
I've had that problem last week and thought I tracked it down to
the NAT
ip
being black listed with one of the span black lists. Even though
that IP
is
not used for mail out, that somehow seemed to affect it. Changing
it to a
different one seemed to solve the problem and I got that original
address
of
the list in the mean time. Changed it back and everything was
well, until
today.
Same symptoms, but now I don't see us listed anywhere.
The best description of the symptoms seems to be that that IP is
rate
limited or something.
Anyone seen that? Are there any blacklists for web access?
Could it be related to the Pushdo botnet SSL traffic generation,

Perhaps you have an infected machine and so your IP is being
blacklisted and/or rate-limited.
