At least some Hetzner offers used to be used servers and they can suddenly fail. I haven't followed them. But I guess you need to think about your backup plans

At least some Hetzner offers used to be used servers and they can suddenly fail. I haven't followed them. But I guess you need to think about your backup plans anyway (depending on what service you run). So using a less reliable provider might just mean that you practice your backup plan slightly more frequently. Some OVH customers can tell you the story when one of their data centers burned down.
