WHAT IS THE IMPACT TO YOU?
The new site firewall protection is based on a new approach using application-based firewall rules.  While this work is expected to be transparent to users, unexpected behaviors with some websites or applications might occur.

WHAT DO YOU NEED TO DO?
If you experience any unusual behavior with a website or application outside of the maintenance window, please contact the Service Desk.
