One interesting fact I've heard recently (I live in Poland; we share a border with Ukraine as well as with a part of Russia).

Russia went all in on "digital sovereignty." This is partly because the Russian government cares deeply about censoring what their citizens can see (which they can't do if those citizens consume content from American services), partly because the American services themselves cut Russia off because of sanctions-related concerns.

This makes Russian datacenters a much more attractive target for the Ukrainians. While Russia can (and does) bomb Ukrainian datacenters, the fact that Ukrainians are so reliant on US infrastructure (and could rapidly move local workloads to western clouds if the need was great enough) makes such operations far less attractive. It's much easier for Ukraine to strike some facility near Moscow than it is for Russia to strike Ashburn, Virginia.

Given the geopolitical concerns from both the east and the west, this makes the question of whether Europe should move content off of US infrastructure a lot more complicated.

I'd heard (from someone trying to use them) that net connections into the Chinese clouds was very busy in the days around the start of the war, so the suggestion is they have critical stuff mirrored there.

Ukraine can have servers outside of Ukraine. No meed to have servers in the USA. I dont think these issues are so connected. As long as the servers are somewhere Russia does not dare to bomb.
