I find it truly amazing that people don't already diversely
monitor.  Hell, have cronned pings running off your friend's cable modem
if that's all you can afford, but for christ's sake, a single box colo'd
in someone else's cage, or a shell at shells.com or nether.net really
isn't that expensive.

Might be interesting to define a set of basic monitoring functions
that independent ISPs can run on each other and share results.  Early
warnings could go to a special email.
