So true! After almost ten years of continuous functioning, one of the hard drives failed and I was left with an unbootable server. Last time I checked it had more than five years uptime. I managed to backup, last minute, things that I should have backed up periodically, and I got a new server, also from Hetzner (whom I warmly recommend, without having any affiliation to them, other than the fact that they are my favorite host for the past 10 years or so).
Sysadmin work sucks. I only do it when the hard drive fails :) so that's about once every 10 years. Still, I was able to put back together my DNS server pretty quickly; also this website, because it's written in Common Lisp. 10 years old software, unchanged, compiled by bleeding edge SBCL running on bleeding edge Arch Linux; now that's stability.
Until the dust settles, comments will be disabled (missing a SMTP server for now). Permanent victims are my old Perl-based websites, including my old blog; I won't bother to get them back up, but there's the Internet Archive if you miss anything.
There'll be a new blog post soon, about Sudoku. I'm not dead yet. :)
