At 12:30 CST I need to reboot the following machines for kernel upgrades: ag-tech.mcs.anl.gov zakim.mcs.anl.gov ag.mcs.anl.gov vv2.mcs.anl.gov ag-2.mcs.anl.gov This will affect AG-2 bridging, AG-1 bridging, the TVS, and AG-1 venue server. The outage should last no more than 10 minutes. Thanks for your patience.
