Yeah, I host three small-scale game servers for an indie-game, all out of pocket. 50-80 players hop on every day and the community is super nice. Its been possible because the price has been €16 per instance, but with these new prices, it will absolutely not be possible anymore. I imagine a lot of small game server communities will meet the same fate now, since Hetzner has been the go-to for this kind of stuff.
I run a few stats site for a video game, and the overall hosting right now is ~€220 on Hetzner for a AX51-NVMe + AX61-NVMe + some extra SSDs + HDDs --- so that's the same price as just a AX42-1 in the new pricing model which is insane. If one of the servers goes down I'd need to likely shut down one of the projects or massively change the architecture.
What do you mean with if the server goes down? As far as I know Hetzner will replace tje hardware for free: "Support services include the free replacement of defective hardware."
I think that's true provided they have replacement hardware - for harddrives/RAM that's almost always true, but a few years ago I had an EOL motherboard issue and was forced into moving to a different server that was a bit more expensive.
There's always lowendbox.com but Hetzner was more reliable than most of those vendors.
