Yeah, but I didn't write "Hetzner sucks because their disks are failing constantly".
One commenter wrote "Hetzner has an excellent reputation for rock-solid engineering" and as a counterpoint I wanted to tell my anecdote which opposes that "rock-solidness". So for that I get downvotes :)
In retrospect yes, I agree that we had to be prepared for such event, to have failovers and so on.
Hardware fails, and part of having a dedicated server is that you are directly on top of said hardware and have to be prepared for it to fail.
