Two issues could be at hand.  The first is that Heritage is on hubs.  10
Mbit hubs to be exact.  That means that when Joe down the hall starts
downloading at 300 KB/s, that traffic gets replicated across 24 to 48 ports.
This would easily cause a shaky network connection and explains why you
experience it during "high traffic" times of day.

The other issue could be one that doesn't happen often, which is why it
hasn't been fixed yet (it's usually hard to reproduce reliably).  It is a
problem with the BYU's DNS/proxy and the only option is to open a trouble
ticket with OIT, give them as much information as possible, and hope for the
best.

Because you say other protocols seem to be fine, I am led to believe that
yours is the second issue.  You can always double check because if the ping
times to www.byu.edu are consistently high (over 100 ms) then your hub is
being brought down by one of your neighbors.  If the ping times are pretty
stable (usually every third request spikes, but the other two are sub-20ms),
it's the second issue that's been eluding the network engineers.  They are
aware of it, and I have been in the room when some of them (the engineers)
have had the problem themselves.
