So, yesterday afternoon...there was quite the thunderstorm.
I could see that the power was flickering at home, VNC'd to 'gumby'. After a while...it was steady on battery. I went over to 'tardis', and watched the UPS run down and cause it to hibernate. Didn't stay to watch 'gumby', headed in to the hallway to visit with evacuees and then go up to watch the storm....and then see about going home.
As I was leaving I saw that my connection to home had gone away. I couldn't remember if I was going into my home network via DSL or Cox. Though based on available data, looks like it was DSL. Will confirm on Monday.
