I will be performing maintenance tonight that will involve a reboot of the main file server to make a new Linux kernel active, and then taking down other machines, specifically shellx, scientific, mail, and ftp, for imaging.

I will not be taking down the other shell servers during this interval, so except for the initial file server reboot, the others will remain functional.  The file server reboot will take place between approximately 00:05 – 00:30.
