Urgent File server sto10 reboot today at 5PM

Greetings,
In order to install urgently required system patches we must reboot the main MCS/CELS file server known as sto10.mcs.anl.gov at 5PM today, January 22nd. We anticipate the outage to last no more than one hour. During this time logins to the login machines and workstations will not be possible and access to most project directories will be offline. You may need to reboot your machine once the system has come back on line.
I apologize for the lack of notice on this, it is an urgent issue.
Thank you for your patience
