Subject: "Network is unreachable"

For a while now, I'm getting the following error when I try to ssh into
sage.math:

  ssh: connect to host sage.math.washington.edu port 22: Network is
unreachable

This is from the computer in my office, on the UW campus.  I can
successfully log in to boxen and from there to sage.math, so I can work
around it, but I wonder if something is misconfigured somewhere.

sage.math.washington.edu is operating with a new IP address
(128.95.224.243). This is accessible from the world at large, but...
looks like it may not be reachable from parts of the same subnet.
Don't know why yet -- will reply back to sage-users when we've
resolved it. Thanks for the heads up.

Not even that, it appears. I also get random failures from Germany.

The local building routing problem has been resolved for now
by backing out of the new sage.math address. Hopefully we'll be
allowed to keep the old address and this will be a permanent fix.

It looks like there was also an upstream networking issue
that got resolved, but unfortunately nothing we can track down.
