> My office was wired with two sets of electrical sockets, one connected to grid mains and the other connected to the UPS (for important equipment only).
This I think is a standard practice in any large office building in France (Europe? Global?) too, regardless of the frequency of the power cuts. I don't remember witnessing any power cuts in the office (not since long ago anyway), but in most of the places there are systematically white and red sockets, red ones being powered through a UPS. So, server machines go into red ones. Well, we don't have servers anymore, but the sockets are still there anyway. Hopefully UPS too, LOL.
