On Monday, October 6, 2008, beginning at 5:30 PM, TSO will perform routine patching of the cc.gt.buzz and gt.buzz AD domain controllers. While this will require that the servers be rebooted, the reboots will be staggered to avoid interruption of services. So, no users should be affected during this maintenance period. All patching is expected to be completed by 8:00 PM, October 6.
