Submitted by stauffeg on Wed, 01/27/2021 - 2:13 PM

Start Date & Time

End Date & Time

Description

Updated at 6:07 a.m.: Maintenance is complete and services have been tested and verified.

The campus border firewalls will be upgraded to new hardware from 5 a.m. to 6 a.m. on Friday, January 29. 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. Please note that there will be a heightened risk of network outages from Thursday night to Friday morning due to prep work for the upgrade. This upgrade is necessary to retire firewalls that are approaching end of life and replace them with newer, more powerful firewalls.

Impact

Between 5 a.m. to 6 a.m. on Friday, January 29, 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. On-campus network traffic between on-campus machines should not be affected by this maintenance.
