Either you are a master troll, or you need to draw a network diagram. You invoked "horrific, inexplicable tragedies" because "surgeons don't properly wash their hands or mark which limb is meant to be amputated". (Frankly I'm not sure the latter qualifies as "inexplicable".) Hand-washing and limb-marking don't require internet access. If hospitals require non-internet-enabled signs to inform surgeons of these risk factors, those are available at restaurant suppliers. (Well maybe not the limb-marking...)

Life support devices also don't require constant internet access. Diagnostic equipment also doesn't require constant internet access. Local medical procedures do not require internet access. Hospital medical records do not require constant internet access. In fact no life supporting activity requires constant internet access, because designing the system to rely on something that is unreliable would be stupid. Physicians are not stupid.

It is conceivable that telemedicine sessions might have been interrupted, but telemedicine is inappropriate when life is in jeopardy. We could imagine the future invention of remote robotic surgeries that would qualify, but if that were going on it would have been mentioned in the indictment, and also a dedicated and isolated network would have been created. In fact since every federal indictment written includes everything but the kitchen sink, and this indictment mentioned only the customary ridiculous inflated monetary damages, we know that this DDoS attack did not hurt anyone physically.

I don't think that we normal easygoing HN folks would really mind your conceptual mistakes, but the combination of those with the withering scorn you've exhibited here is probably what inspired us to keep this thread going long past the point of interest and utility. So, nice trolling!
