datacenter evacuation / replacement options

First off, we are not currently planning to migrate, replace, or evacuate our presence at Hetzner or any other provider. That is a massive undertaking that we would not want to embark on without a significant cost/benefit analysis. The last time we evaluated this (#41374), we decided to stay.

That being said, it seems to me worthwhile to keep an eye out for other ... opportunities in hosting servers, specifically in Europe, but this could also include locations in Asia our south america. The point is to have diversity here.

Our hardware requirements have been expanded to cover for hosting requirements found during the Cymru migration (#40897).

So this issue is to keep track of such ideas as they come up. Ideas should be documented as (possibly internal) comments
