That's a very good question - I hadn't tried monitoring my bridges
with it because I had other means.  Fortunately, a reboot to a bridge
doesn't set it back like it would a relay.  Users of the bridge are
inconvenienced (maybe) while it's offline, but cheap VPSes are *great*
for dedicated bridges, and 128MB RAM is currently enough.

Best,
