This is from a terminal window I haven't used for a couple of weeks. I snipped the "Warning power loss detected ..." from all entries but the first.

It has been like this for at least a few months. What happens in my neighborhood around 6 in the morning that makes the voltage in my power outlet go down enough for the UPS to pick up? I don't recall our giant UPS we had at Netcetera in Brolæggerstræde (in Copenhagen) ever doing that. Not umpteen times a week anyway. And they just did maintenance in my street!
