I looked through the issues and basically only ongoing thing is that backup power is not working in one of the data centers (could be a problem). The rest are warnings about planned shutdown of some services and speed limitation of object storage in one location.

I am sure it's luck but we have few hetzner VPSes in both German locations and in last 5 years afaik they've never been down. On our http monitor service they have 100s of days uptime only because we restarted them ourselves.
