Something like this doesn't happen by accident. Three cities, same night, military exercise that apparently "nobody knew about" until someone dug up the FOIA request last week. I've been watching infrastructure anomalies in the UK and US for about four years now and the pattern that keeps coming up is that these blackouts tend to cluster around specific grid nodes, not randomly distributed across a network like you'd expect from a genuine fault.
What bothers me most is the timing window. The outages didn't all happen simultaneously, they were staggered by roughly 40 minutes each. That's not a cascade failure, thats a sequence. Something was being tested, or something was being covered.
Anyone got the actual city names confirmed? I've seen three different lists floating around and I'd rather work from verified data than chase the wrong thread down.
