Description
The campus border firewalls will be reverted back to their original state between 10 pm and 11 pm on Friday, August 14, following an unsuccessful upgrade on August 13. During this window of time, all network traffic to and from the campus will experience an interruption of approximately 15 minutes. This may result in the need to reconnect to services if they do not automatically reconnect. This maintenance is necessary to reinstate border firewall redundancy.
Impact
