> Instead of targeting data centers, it's far easier to target the electrical substation that powers the datacenter That has a lot of collateral damage that may or may not be desirable though. Simultaneously it might have quite a different long term effect right? If all the actual computers are unharmed they can be powered in other ways in an emergency, even if at much higher cost. Or powered back up later, the time…
Any cloud engineer worth their salt is going to have their programs be stateless and their data replicated across multiple data centers. Many cloud engineers are not worth their salt, but working in Big Tech, this has been table stakes for 20+ years. There are regular disaster drills, both scheduled and unscheduled, that test what happens when a datacenter disappears. Ideally everything transparently fails over, and…
That doesn't help much in a shooting war, unfortunately.
