Hi Frens,
I'm in swamp sprawl and my apartment building and buildings around mine quietly lost power for 45 minutes last night. Interesting, huh? A test run? Some sort of high speed event? I live near a military base and there was also a very loud bugle call at 11 PM last night, I've heard bugle calls before from the base but I can't recall hearing one at 11 and I can't recall ever hearing one so loud.
Blackouts are an interesting thing, less a weapon aimed at dissident people within the armed forces I think.. and more likely to be something aimed at big tech. If you have a lot of datacentres near where you live with google/facebook/AWS footprints (not that these things are advertised generally) then that's the likely battlefield for using power and service outages to take out enemy assets.
Bottom line, dont park your car near any generators which you have never seen used, its a time that they will probably be fired up for backup power when things get hot.. and will also be targets for that reason.
