[Major Incident] vole.cse.umn.edu – SSH connection shut down abnormally

At approximately 10AM today, CSE-IT began receiving reports of issues regarding  linux systems rebooting.  There was a problem with the scheduler for the task that was supposed to have rebooted systems at 4 a.m. this morning.  That reboot was announced last week.  A full postmortem will be done to find the exact cause of the problem.
We are very sorry for the problems this caused.
