It seems strange now how often the power goes out. I remember back in the '90s I could leave my PlayStation running for two weeks because I didn't have a memory card to save my progress in Syphon Filter or NASCAR Thunder '98. Nowadays I have to set up autosave on everything and make checkpoint safeguards or scheduled backups because the power flickers off and back on at least once a week. This, with much more power efficient devices than that old PlayStation and Panasonic CRT.
It tends to happen in the area in general where I live. My house, neighbour's house, a house a mile away, all have the same trouble. I live within about six hundred yards of a volunteer fire department and about seven hundred yards from an elementary school, and even they've complained about how often the power goes out. The worst part is it's not like it's off for a few minutes and then it's back on. It's a momentary tenths of a second thing, like someone flicking a light switch down and up once to get people's attention.
This can vary greatly across locations, even within the same city and the same power distribution organization.
Different neighbors, being on different circuits, being on a line that's more likely to have storm damages, can make a lot of difference in quality of power delivery.
I've lived in places where the power practically never went out, never experienced undervolt situations, etc. I've then lived less than a mile away from the same place and experienced seemingly monthly issues of all the clocks being reset at random times when I come home. Living closer to things like hospitals, fire stations, emergency operations centers, etc. seem to give the best indication of power reliability, at least from my personal experiences.
