Power Loss = Fail

So I happened to notice today that my phone claimed that it wasn't able to sync mail from home since 1:30pm. Though when I'm at work it often fails to sync since it uses wireless at work and it blocks outgoing non-proxy connections, and won't proxy IMAP. But it didn't sync when I was away from work for 2 hours (on a 1 hour sync), even when forced. Okay, now I'm thinking that my IP changed and my dynamic DNS hasn't propagated yet. No worries.

When I get home I notice the stove clock blinking. I walk back down to my laptop, and notice that the tuner is on standby, which is a pretty good visual indicator that I lost power.

So clearly I lost power long enough for the UPS upstairs and the UPS in the garage to fail, and for some reason only 2 out of the 5 machines on a UPS came back (HTPC isn't protected, I didn't bother pinging NAT/DNS, since it was obviously working).

At some point I should figure out what's dead on marduk. Sadly, I was about to move some of its components to a new computer, guess I have to buy more parts than I thought.
