Hetzner is a dedicated server (meaning monthly contract, 1 month setup fee and up to 1 week delivery time) company that branched out into cloud, so it's not that surprising they treat cloud a bit like that. While Amazon wants you to think they have an infinite capacity pool, and any failure to get a server is an unexpected error, Hetzner seems to not hide they have a finite number of servers in a finite number of racks, since that's how their main business works.
