Description
Update at 6:50 am, January 12: the upgrade has been backed out; all internet service has been restored.
The campus border firewalls will be upgraded to new hardware from 5:15 am to 6:45 am on Tuesday, January 12. During this upgrade window all network traffic to and from the campus will experience an interruption of 5 to 10 seconds. This may result in the need to reconnect to services if they do not automatically reconnect. This upgrade is necessary to retire firewalls that are approaching end of life and replace them with newer, more powerful firewalls.
Impact
