Starting around 9pm, I will be taking various servers down for reboots (kernel updates) and imaging.  The main file server won’t be done until after midnight, and same for mail and web servers, but other shell servers will be done earlier starting with the least busy.

This work will take until about 2AM and might possibly be continued on Saturday evening if everything isn’t finished Friday evening / Saturday morning.  All the Redhat machines have kernel updates and a huge number of updates (over 200 each) to install, the Debian based systems mostly just need to be imaged.
