Wait, I think we are talking about two different things ... I'm not 
looking at 'how long its been up', I'm looking at % of time its been up 
... rebooting a server once a month to upgrade it, even if its down for 
5min, is about 99.989% uptime, which is a good number, but the OS is still 
up to date ...

The 'metric' one should be looking at is how *much* the server is up, not 
how *long* ...
