The world is absolutely full of things that have worked for decades to centuries without the Internet, are eventually more or less consistent (remember carbon paper credit card machines?), and did an amazing job of keeping the world running despite, wars, network partitions (the “network” would basically always be partitioned), mistakes, entire branches offline, etc.
Sure, a lot of things are easier when centralized, and “the cloud” is incredibly powerful. But it’s not necessarily more robust. Also, depending on any sort of cloud means you’re also depending on the network, and networks are far from infallable. There’s a reason that a lot of stored-value transit systems still track balances on the card and will let people in even if a fare gate cannot connect to a cloud service.
And CrowdStrike took out plenty of cloud instances, and recovering them can be worse than recovering physical hardware, as the “robust cloud” has an absolutely terrible ability to do anything outside the happy path of booting an instance normally.
