I'm currently renting around 40 x AX-line machines from them. The random reboots are a real thing, but not painfully so. I would say I see around 5-10 a year on average across all my boxes, so (very roughly) that's one random reboot per 50-100 machine-months.
I asked them about one of the incidents, and they said that the breaker serving the rack had popped. I would guess that is a fairly common cause of this problem.
Another issue is disk failures. They replace the disk incredibly quickly (<1hr) but unless you are willing to pay for a brand new disk they fit whatever they have in stock. Sometimes that seems to be a unit which is itself close to death, and in another couple of months, guess what happens. Mostly they give you something reasonable so it all works out in the end.
Hetzner are a discount cloud provider. For the money, I'm basically delighted with them. The only other realistic option at a similar price point would be to self-host... and I'm not at all convinced that would be worth the hassle.
