That's all fine, but this time, no one could get those computers back up in the first few hours, since they were stuck in a boot loop. Plus, systems like hospitals had to be running all that time. Plus, at the scale this outage is reported to be - banks, stores, factories, phones, emergency services, CNC machines, networking, aircon - I imagine everyone was confused and trying to figure out if anything works.
I'm happy nothing significant was hit over here in Poland; reading the main HN thread on the outage feels like reading war reports.
