Just as I'm getting ready to set off to church (bright and early - I was on the projection rota today), the power went out! Fine, I can carry on by torchlight.
Of course all the smoke alarms in my flat then took the opportunity to demand fresh batteries.
At church we had no sound coming through the main PA, despite the desk and amp being live and sound coming fine through the aux PA and foldbacks. Turned out someone had switched off one of the many plugs, which happened to power the equalizer for the speakers and the induction loop. We managed to track that down about 10 minutes into the first service (when most of the A/V rack has power, it's not obvious that a little neon right at the bottom is off).
Also at church we had no heating! It's a hot-air system, and it appears that the blower for it has packed up (so the boiler room was nice and toasty but nothing else).
Anyway, I'm now back at my flat and have power once again. Two of the alarms have been fed - I need to pick up more batteries to feed the heat detector in the kitchen - and hopefully now it's the afternoon that's it for today's fail!
