There will be an emergency maintenance for the University firewall on April 16th, starting at 5:00 pm and lasting until 7:00 pm. This emergency maintenance will allow Network Services to install firewall software updates to patch a known critical vulnerability. While initial vendor-recommended measures have already been taken to mitigate this vulnerability, a software upgrade is now recommended as a permanent fix. There is currently no connectivity outage expected; however, the entire maintenance window is reserved.
