Due to a serious security vulnerability, we will be patching all RCSS clusters on Monday, October 31 at 7:00am. The outage should only last a few hours. The teaching cluster (tc.rnet.missouri.edu) was patched today.There is a slight chance that the patching may not go well with Lewis3 and it may not return to service as our original plan, which was to shut down Lewis3 at the end of the month. If Lewis3 does return to service Lewis3 will remain operational for at least an additional week.
