I'd be more interested in the computer system with the longest uptime. I've had Debian systems that have achieved over 1 year uptimes. Could have gone longer but kernel upgrades took precedence over uptime.

I was asked to look at something on a Debian box the other day and logged in to discover over 2 years have passed since a reboot. A bit dangerous, but also wonderful to think about all that data flowing through without issue.

I love the idea of that, but it also means no security patches for that same period of time. I'd be weary of placing that host in any network with publicly-routable hosts.

No security patches to the kernel. You can certainly upgrade user-space items (daemons and the like...)

You can use stuff like https://github.com/dynup/kpatch or http://www.ksplice.com/ to apply security patches to a running Linux kernel, but that's still pretty new stuff.

Stratus has been doing that since the 90s, though :-)
