alt Hacker News> 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.

US typically has the whole office with UPS and diesel generators (if it is important enough to do so).
But all the nuclear power bros told me electricity in France is uber reliable and bountiful because it's all nuclear! We need nuclear power plants for a stable grid!
It's almost like grid inertia is a different problem from matching changes in demand, and nuclear really sucks at the latter...
Putting computer systems on UPSs isn't a Europe thing. Backup generators and UPS units are very common, or at least they were until everyone got infatuated with moving all their data "into the cloud" and stopped maintaining, or building, infrastructure in office space for it.
Now everyone has all their eggs in the Amazon/Microsoft/Google basket, and instead of the (ahem, regulated) telco or electric company going out...the cloud provider does, and unlike before where you could still work locally - now you can't do anything.
But hey, it was cheaper, right?

I've never seen them in France. I've seen them in a chemistry lab section of a university in New Zealand and I believe they're also common in data centers, NOCs, etc. worldwide.
