This may have been long discussed, but I feel like this war is the first time I've really thought hard about how big a target data centers would be in any sort of modern peer war and how that's an entirely new thing since the last time it was really on the radar (end of CW) right? We've built trillions and trillions of dollars in infrastructure in the peace time since, and it seems fairly concentrated. AWS is amongst the biggest there is, and according to mappers like [0] there are only around 240 operational total worldwide with another 130ish under construction. Like, in one respect that seems like a bunch, but vs the kind of attacks we see done in a matter of days in modern wars it's a pretty small number for the whole planet isn't it? In the first 24 hours of the war the US and Israel launched on Iran, they hit something like 1500-2000 targets. How hardened are the data centers? Are they in structures that handle some level of explosives? Do they have counter measures like internal blast walls dividing things into cells so a few hundred pounds of high explosive in one area doesn't damage outside the cell? I mean, of course like all data centers they'll have considered extensive countermeasures to fire, environmental threats, grid issues and so on. But has "nation-state level attack via mass drones or bombardment" been part of the threat model over the last few decades? Hardening of telecoms was certainly considered for old Ma Bell and such back in the CW days but that was a very different environment.
I guess it makes me think about what a soft underbelly this could be for a lot of modern society. There's always been consideration of threats to refineries and power stations and industrial production and all those big metal deals. But like, forget any sort of nuclear exchange, any sort of crazy super Starfish style big EMP, just purely a few thousand drones nailing data centers. Nobody even directly dies, just a lot of wrecked computers. What would be the cost of losing all the clouds and colo stuff? How long to replace, at what cost? How much depends on it?

In any significant war the Internet is going to go down. That's what has happened empirically in countries undergoing significant wars or social unrest, like Russia, Iran, Yemen, Ethiopia, Syria, Myanmar, and Afghanistan. While IP packet routing itself may have been designed to survive a nuclear war, there have been many centralized systems built on top of it (DNS? Edge caching? Cloudflare? Big Tech) that are essential to the functioning of what we know of as the Internet.
If your threat model includes war and you want to have some of the conveniences of the Internet, you should make plans for how to host local copies of data and develop local-scale communications for the people you regularly talk with. The Internet is too big of a security and propaganda risk for governments to allow it to continue to exist when they are engaged in a real existential war.
Some systems are anycast and available in many datacenters for bandwidth cost reasons. Netflix used to deploy content caches in ISP edges.
But any single central point of failure might break them. Things like, is this account paid? Dunno!
