I just checked back and it's still up ...

ck at hostname: {8} uname -a
FreeBSD hostname.domain 2.2.2-RELEASE FreeBSD 2.2.2-RELEASE #0: Mon Feb  9 18:53:29 CET 1998     ck at hostname.domain:/usr/src/sys/compile/XXXXXX  i386
ck at hostname: {9} uptime
 9:44PM  up 2204 days,  2:38, 1 user, load averages: 0.48, 0.24, 0.10
ck at hostname: {10} date
Sun Feb 22 21:45:29 CET 2004
ck at hostname: {11}

hostnames and domains changed to protect the innocent.

Of course this does not make much sense and the customer in question
would be well advised with an update. Have been talking to them.

Our own production servers regularly reach 200 days and more. We update things
like ssh and openssl in place and only do full buildworld/installworld
upgrades perhaps once or twice a year. Lot's can be done while staying up.
Jails help a lot of course. Not having external users with shell access also
