We have been tracking an urgent security patch needed for Banner production. We plan to install this tonight (27 May 2026) starting around 8pm. We are making preparations for this now.

Starting around 8pm and continuing for at least 2-3 hours, you should plan for Banner and related systems to be unavailable. We strive to complete the upgrade as quickly as possible but sometimes need the extra time to finish everything. Rest assured we will make the system available again as soon as the upgrade is complete.

The following primary systems will be unavailable during the upgrade:

• My Missouri State
• Admin Banner
• Argos, including Bear Intelligence
• Banner Document Management (BDM)
• Self-service 9, including Employee Profile, Student Profile, Registration, and Faculty Assignments
• Custom web applications (Grails and Django), including Who-What, ATLAS, and Class Dashboard
• Any other system that relies on a direct connection to Banner

The following systems will not be impacted:

• University networks
• Phone systems
• Main (public) websites
• Brightspace
• Office 365
• Email services
• Video surveillance systems
• Electronic door access
• Application for admission

We apologize for the short notice and any disruption this might cause. If you have questions, please contact me via Microsoft Teams.
