I guess that depends on a server, but all my non-Arm servers are on Arch, and it’s been rock solid so far. (Years, close to a decade.) What I like is that I don’t need to upgrade it (meaning across versions), I just update it here and there, non-regularly. Never had a single issue. Perhaps I’m lucky and asking for trouble. One machine runs root on an encrypted RAID-0, so I’d test my backup strategy. Another one runs root on RAID-1. Another one runs root on USB drive.
