Earlier quoted context omitted.
We went with Hetzner as we already had good experiences with their VPSes. For this particular db migration, a resonably sized VPS with volumes does the job for us. We don't have planet scale operations so the lowish IOPS is not an issue atm. Also, with this experience at hand, I am confident that we'll manage another migration if need be.
Afaik Hetzner has a couple of server locations in the USA. Is it correct to say that Hetzner has to comply to US CLOUD Act and therefore give away any data requested?
The one under US jurisdiction operated by Hetzner US LLC must comply, while the German ones are operating under the GDPR, which has extraterritorial clauses can can deny or challenge the request.
