  IP routing has become more and more of a concern to many of us,
as routes become stranger and stranger.  Earlier this morning, we
were unable to find any routes to milnet.  Just now, I tried again,
and found that the route is, to say the least, a bit strange.

  It looks like the mailbridges are doing quite a bit of passing
the buck between each other.  I have attached some traceroute
outputs to the bottom of this message.  They were all taken in
a one minute period.
