alt Hacker NewsRegularly (every 3 years or so) had 1000+ days of uptime with FreeBSD rack servers on Supermicro mobos.
I built the servers myself and then shipped to colo half way around the world.
I got over 1400 once and then I needed to add a new disk. They ran for almost 13 years with some disk replacements, CPU upgrades, and memory additions
Genuine questions:
Do you ever apply kernel patches? I also run FreeBSD and reboot for any kernel patches and never can get my uptimes to 1,000 days before that.
Do you just run versions that don't get security patches? Security support EOL dates generally means I need to upgrade before 1,000 days too. For example the current stable release gets security patches only from June 10, 2025 to June 30, 2026 giving just over 360 days of active support.
I get FreeBSD is stable and get days of uptime, and I could easily do the same if I didn't bother upgrading etc, it's just that I can't see how that's done without putting your machine at risk. Perhaps only for airgapped machines?
