Your highest uptime…

clock1

Uptime is a measure of the time a computer system has been “up” and running. It came into use to describe the opposite of downtime, times when a system was not operational. The uptime and reliability of computer and communications facilities is sometimes measured in nines (similar to the unit of metallic purity). “Five nines” means 99.999% availability, which translates to a total downtime of approximately five minutes and fifteen seconds per year.

It is often used as a measure of computer operating system reliability and stability, in that this time represents the time a computer can be left unattended without crashing, or needing to be rebooted for administrative or maintenance purposes.

Current record for longest uptime is 11 years, 303 days, 20 hours and 57 minutes on a computer running OpenVMS.

The commands used to find out your system uptime:

- Windows Xp, 2000, Vista:

systeminfo | find “Up Time”

or if it doesn’t work, you can use the microsoft uptime utility (direct link) which runs on any version of windows.

- Unix:

$ uptime

- OpenVMS:

OpenVMS $ show system /noprocess

The uptime of a personal computer is sometimes displayed as a badge of honour on an email signature or web site/forum.

So… what’s your highest uptime?

    I was just google-ing this – because I just ran into a NT4.0 system – that will be going on three solid years of uptime in a week or two.. it’s gotta be a record for Windows at least! lol, nuts.

    The command for NT4 (and it looks like server 2003 will take it too) is: ‘net statistics server’
