You are right.  It actually happened earlier this week, it was Monday or
Tuesday if I remember.  I know because I was the one who took the call and
notified the network engineers.  I had to go to class, but the resolution
was so:

The CS department found the port 80 of their inet proxy was being blocked by
OIT's connection.  They figured this out because by bypassing their proxy,
they were able to use web traffic.  The network engineers started looking at
changes on our end, but they hadn't made any.  The CS department called in
later (I think it was an hour later...) and said they had changed the ip of
their proxy to an address that was 3 from their last address.  They had port
80 connectivity for about 5 minutes and it was gone.  The network engineers
checked (here's where it gets over my head) and found that something behind
the CS department proxy was sending out network traffic strange enough over
port 80 that the automated system blocked it.  Either it was too much, or it
was a malware/virus related traffic, but the system auto-blocked it.  The
sysadmins from the CS department said they would investigate more on their
end and turn off whatever was going on.  Time to resolution was less than 3
hours.

But since OIT just turns port 80 off for an entire department at random, it
had to be their fault...  They also work entirely too slow...

>From what I've heard, at least in the CS dept, OIT has been doing this
on and off during this semester.  I've also heard of OIT blocking port
80 for the cs dept.
I'm not one of the sysadmins --- they could probably provide better
info than I could...  These are just some rumors that I've heard from
rather reliable sources.  Torrie appears to be having the same problem
from the chem dept as well...  Very interesting...

Doesn't appear to be happening in the cs dept at the moment, but I do
know it has happened in the not-too-distant past (past couple weeks or
so?)
