Log off your computers...

From the folks at IT:

As part of our regular maintenance, we have scheduled a file server upgrade this Sunday, January 29, 2017 after 8:00 PM.  Please log off from your computer at the end of your workday this week (Friday, Saturday or Sunday) by 8 PM on Sunday. You don’t have to turn the computer off.  Failure to log off your computer may result in delays restoring access to your network drives.

So if you have a computer and you're not working on Saturday, please log off when you leave on Friday afternoon. If you work Saturday, please do the same that day.
