Yeah... Ours went out at work, but it was daytime and the shop has large windows and skylights. The only dark areas was the bathrooms. It was only out for 2 hours, but since our phone system is not hooked to a UPS system, no phones worked.
I had my power at home blink a few times this year with those several storms midwest heading east, but its only like a few minutes. Regardless I went to find an led light, turn off the automatic filiment lights, grab an old wheelchair battery and inverter and prepare to hook up my fan, tv and floor lamp.
