Someone just learnt that touching live power cables is a Bad Thing(tm). Think he was repairing the street lights. He's managed to take out a large chunk of the power in the area. Means I get to sit around here, twiddling my toes and listening to the dulcit tones of a dozen UPS screaming about the lack of power.
EDIT: Everything is back to normal. Hurrah. And amusingly I was the only person not to wuss out and shut their machine down :) Don't think it was down for more than an hour.
