*What is happening?* On Sunday, July 5, 2020, from 11:15 p.m. - 11:50 p.m., US:IT Staff will be performing a non-disruptive upgrade of the application load balancer environment supporting multiple enterprise services. The major enterprise web services utilizing the enterprise services load balancer are: - UMS Single Sign-On - MaineStreet - MyCampus Portal *Due to the redundancy in the load balancer environment, no service outages are expected during this maintenance.* *Why is this work necessary?* The vendor has released two critical security advisories for our load balancer systems and recommends that a patch be "immediately applied" to mitigate any risk of misuse. *What happens if this work is unsuccessful?* If any service-disrupting issues occur during this maintenance process, we will return to the configuration in place before the maintenance, and work with the vendor to diagnose and resolve the issue. If there are any questions or concerns related to this non-disruptive maintenance, please feel free to contact me.
