Yeah this actually caught my attention too. We had two "unplanned" outages in my county last October and when I pulled the old utility calendar from the state archive site, both windows matched up within like 20 minutes of the original scheduled maintenance slots from the previous year. That's not a coincidence, that's a pattern.
What gets me is the utility companies don't publish these schedules in any centralised place, you have to dig for them. Most people never bother. So when an outage hits and they call it unexpected, nobody's cross-referencing anything.
Not saying I know what it means yet but something is being coordinated and the "maintenance" label is cover for something with a repeating cycle. Has anyone actually mapped these out across multiple states? Would be useful to see if the timing clusters geographically. Someone with access to FOIA docs on grid management could probably connect some dots here.
