fetch hangs on 6/24/04 current build

[Conrad J. Sabatier]

I just upgraded both of my machines today, and since then, I'm getting
lots of hangs during port fetches.  I don't know if this is just a
local problem, or a problem with my ISP's routing, or what.

Any recommendations on how to diagnose what's going on here?

Here's my LAN's topology:
