Ah sorry I should have been clearer on this -- "global cache" === CDN. Hetzner does incur a performance latency (unless you use the brand new US DC of course, and your customer happens to be in the US). IIRC right now you can't mix US cloud servers and German ones in the same Load balancer (also a relatively new hetzner cloud feature) but of course you can do some DNS tricks and get the loads to be fast.

Actually hosting files is super easy (Caddy is awesome, NGINX is awesome), but it's even better when you don't have to set up the server at all, for example just turn on "HTTP access" on a object storage bucket for example. So this is another place Hetzner kind of falls short though they do have hosting options[0], so basically the ideal solution here would be to deploy a simple Hetzner app (caddy/nginx or the hosted options hetzner has), set up a cheap CDN (Bunny, Cloudflare, etc) in front of it, and save money that way. If the bill is still too high just take the penalty or bias towards one geo (germany/US).

I was less talking about the difficulty of getting a server up and more about the CDN bit of the issue to make loads blazing fast!
