*What is happening?*

On Sunday, May 3, 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?*

After our successful transition to new hardware on April 22nd, the vendor
recommends that we upgrade software to receive security fixes and
performance improvements.

*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.

Steve.
