There will be a very short downtime (just a reboot) to put a new kernel into place on the two machines, Thebes and Memphis, which comprise our shell.cs.utah.edu service.

Thebes will be rebooted at 18:00 and Memphis will be rebooted at 18:30.  The downtime should be just a few minutes, but be prepared for a bit longer should the filesystems need checking during boot.
