Yeah I mentioned banking because of what I was familiar with but medical industry is going to be similar.

But they do differ - it’s never ok for a hospital to be unable to dispense care. But it is somewhat ok for one bank to be down. We just assume that people have at least two bank accounts. The problem the banking regulator faces is that when AWS goes down, all banks go down simultaneously. Not terrible for any individual bank, but catastrophic for the country.

And now you see what a juicy target an AWS DC is for an adversary. They go down on their own now, but surely Russia or others are looking at this and thinking “damn, one missile at the right data Center and life in this country grinds to a halt”.
