Hetzner S3 support

However, I would like to point out that Hetzner does not provide explicit uptime, for this reason I only use it for data uploads.

Yeah. Judging from the Hetzner status page and what I read on the Hetzner subreddit, their S3 storage doesn’t have the same quality as their other offerings yet. I’m sure they’ll eventually get there, but right now, semi-regular downtimes are to be expected.
