Being quite rural we are on overhead line supply, and power cuts are not that uncommon.
Yesterday was a nightmare. Power would go off - flicker on a couple of times as the automatic re-closer tried to re-connect, then go off for a period. When it came back on, I'd leave it for quite a long period to be sure we were stable, then go the rounds re-starting PC's, resetting timers etc. Worse bit is the front gate which is electric powered. Had to manually over-ride it, but if the power comes back on the manual over-ride has just dropped a dog clutch, so the motor is turning trying to close the gate.
I have a small generator, as our sewage plant needs power, and ALL water used on the place goes through it - so if power is off for more than a few loo flushes I have to start it to pump out the treated effluent or it over-flows

We went through this sequence SIX times yesterday - infact after the fifth, it came back on and I started typing this whinge, and it went off again as I typed

A few things come out of this:
a/ I must replace the three timers for lights and pumps with ones that don't loose their settings when the power goes off
b/ I must consider UPS's for the PC's, though they are distributed over three buildings
c/ I must investigate a bigger automatic change-over generator that will power the lot. (Cottages power is sourced from our house supply)
We have a pair of holiday cottages on site, and when people are on holiday you can't really tell them to cross their legs for extended periods, and oh by the way you are locked in as the gate doesn't work
