I thought it might be an MTU problem:

I set my MTU to 1300, but that hasn't helped.

DNS is working fine everywhere, so I don't think thats it. PTR is
fine, reverse lookups work fine.
I've googled my brains out. Does anyone have any ideas?
Intermittent network connectivity problems could be a firewall problem
or an actual physical connectivity issue. Presumably your ISP can run
a line quality test or something for your DSL/cable/T1/whatever link.
tcpdump might give some insight, also....
