Thanks to brannanjp for the explanation that power lines were down across Pine Tree Road; East Hill Plaza and surroundings had already gotten their power back, but we were out until 12:36, just as I had grabbed the flashlight to assist in going to the bathroom before bed. (I always know where my flashlights are.)
I was reminded that I got an alarm clock with battery backup! It came back on with the correct time. :-)
Now to make sure the TiVos came back up successfully, and poke the audio streaming on the Windows 2000 machine.
