*What is happening?* On Wednesday, April 22, 2020, from 6 a.m. - 7 a.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?* Our current hardware has reached the end of its support and service life. During this maintenance, we will be transitioning to new hardware, which will ensure that we can maintain support on this critical component of a number of enterprise services. *What happens if this work is unsuccessful?* If any 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.
