"System Maintenance"

I've been working on a large data exchange with our Intralink server and was apparently a little over zealous with my purging. As a result I had send out the following message to our CAD users...

"Please do not save to the Intralink database for the rest of the day. I have to perform system maintenance that will take approximately 8 hours. You can still work locally. Just do not check-in as you will lose your work."

Ahhh the old "system maintenance" message.

system maintenance (sis•tem mâne•ten•ens) -
The reason a System Administrator gives for having to restart the server after he has messed something up.
