Unix variants in general have extremely low downtime requirements compared to pc operating
systems. Same goes for linux in my experience. Linux servers with hundreds of days uptime are
the norm here -

plemlp01: /home/jjs
(tty/dev/pts/0): bash: 113 > ruptime -t
plemlp05      up 611+06:38,     0 users,  load 0.02, 0.02, 0.00
plemlp04      up 611+06:31,     3 users,  load 0.08, 0.05, 0.01
plemlp03      up 611+06:16,     1 user,   load 0.00, 0.00, 0.00
plifsp05      up 607+00:23,     0 users,  load 0.02, 0.05, 0.05
plemlp01      up 607+00:04,     0 users,  load 0.11, 0.08, 0.08
plemlp02      up 607+00:00,     0 users,  load 0.52, 0.39, 0.35
plemlp01: /home/jjs
(tty/dev/pts/0): bash: 114 > cat /etc/SuSE-release
SUSE Linux Enterprise Server 10 (i586)
VERSION = 10

But this is nothing new - I had a couple of busy production mail/dns servers back near the
turn of the millenium which were up for over 2 years - but that was on the 2.2.17 kernel, and
uptime would wrap around at 497 days. No problems whatsoever in the performance, they kept
running for hundreds more days til we brought them down for hardware upgrades.

At any rate I'm glad the mainstream "IT pundits" are catching on.
