Description
Update at 10 pm on 11/23: This change has been postponed to allow for additional technical clarification from the vendor and will be rescheduled to a future date.
The campus border firewalls will be upgraded to new software from 5:45 a.m. to 6:30 a.m. on Wednesday, November 24. During this upgrade window 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 upgrade is necessary to optimize traffic processing and increase firewall performance to alleviate some minor packet loss we have observed.
Impact
