Which fire? Are you not confusing with OVH SGB2 fire in 2021?
I also had problems with Hetzner hardware ~10 years ago, as in servers randomly freezing due to CPU bugs. But in the past few years I haven't encountered problems at all. I have two dedicated servers for running CPU-intensive CI/CD workloads and for the past few years they've run smoothly.
Hmmm I think you're right.. the fire was at OVH.. But I recall something in the past 2 or 3 years about dataloss at Hetzner.
Personally I only had some network issues with them.
I heard it was pretty hot
(sorry, couldn't resist)
