I've used them for more than 15 years. Their business model started and still is to some degree desktop grade components for cheap servers and they've also added more server-grade components/systems in the last years. Generally their service is good, but there are some tradeoffs. With Hetzner it's mostly network redundancy and sometimes power. I have some experience with DC design and one of the most expensive and rarely used part is creating a fully redundant network layer. You're basically investing for something that you'd use rarely and most clients won't treat is as a differentiation to pay more for it. So even if you get some downtime you won't lose that many clients in the long run. If you are cost conscious and know how to manage your servers you can get a very good value for money with them. A mix of bare metal and some VMs can give you HA and performance. There are some downsides, some protocols are filtered on the network level locally so it may be more tricky to build a fully HA solution, but still it's much better than OVH, their only true competitor currently. Also, they have a Finland DC now, so off-site backups are possible. And the price structure is predictable and you won't get that emotional high of getting those damn AWS bills that always grow.
