You don't think they'd rather maybe find alternatives rather than shutting down? Sure, it'd be sucky probably for a long-time, but it's not like we don't have IT professionals who can stand up physical servers, email servers and what not, plenty of local municipalities do so already, so somewhere there is expertise already.
People generally don't just give up and throw their hands in the air in the face of difficulties, even less so when the governance of their country depends on it.
I think you are underestimating the supply chain problem. You can't stand up extra servers you don't already have in extra data center capacity you don't already have. The whole point of the cloud is that you don't have these assets.
While you can acquire these assets the lead times would be several months at a minimum, and probably years if everyone is trying to do it at the same time. It isn't an issue of knowhow, the required physical infrastructure doesn't exist.
