Heh! Had this happen to me yesterday: couldn't telnet to it, ping wasn't
working.. yet it was still answering the phone. Turned out that it had
spontaneously forgotten everything, including it's IP address. Had to
rebuild it from scratch. A very.. educational.. experience. :-)
(I'm not worried; this was only the second screw-up in 8 months of
operation, and I'm willing to blame the electric company.)
