Hetzner is a very particular product. They openly cop to being "overly cautious" with even letting people open accounts because they're playing with razor thin margins: I wouldn't engage with an organization like that for serious production workloads.

At least, where "serious" is defined as making enough money that paying AWS $200 a month for $20 a month worth of compute is worth it in exchange for an actual SLA*, paid support, and knowing that even if you drop of the face of the Earth, the account will probably run unfunded months before your users even notice.

I've been bitten by using "quirky" tier-3 providers for savings on projects that really should have just ate the cost of a bigger provider.

(* Yes an SLA is not a magic uptime guarantee, but it creates an expectation which is a lot better than nothing.)
