My desktop (laptop, really), which runs Ubuntu, I update all the time, but with
my servers, I'm more careful with the upgrades I do.

The server I maintain, which hosts ntuoss.org and sg.releases.ubuntu.c­om, runs
Debian, which provides security updates or bug fixes with minimal impact to
their stable releases. I generally apply those updates and do a little testing
after, because they've already gone through a considerable amount of testing
before being released into the repository and are quite unlikely to break.

That said, updates always do pose a risk of breaking your system, usually
proportional to how big the update is, so I usually keep an eye out for packages
that are essential to the server's operations and make sure they continue
working after. And for major distro upgrades like from Debian Lenny to Debian
Squeeze, I prefer to have physical access to the machine before running the
upgrades.

On the other hand, like Harish said, by not updating your server, you're just
setting yourself up for trouble. Skipping security updates can leave your server
open to known security holes, which can in turn lead to your server getting
compromised. And the cost of recovering a compromised machine is much more than
the cost of recovering from a borked upgrade.
