Windows Update to Cause Delays in Document Processing
Investigating - S Situation

On November 17, 2026 between 12am and 6am, Windows OS 2022 will be pushed to the two document processing batch servers, which are currently utilizing Windows 2016. This upgrade may cause document processing via automated batching to be delayed (i.e. documents via Experian and Tonic). This may also cause delays for Advanced Capture and Kofax, utilized by Medical Records. The documents will be queued for processing once the servers are back up.
________________________________________________________________________________


B Background


Windows Operating System 2016 will no longer be supported soon, so an upgrade to Windows OS 2022 is required.
_________________________________________________________________________________


A Assessment

Outside of the maintenance window, if images are not processing as expected, please enter a ticket with examples so we can confirm receipt of the document and queuing as anticipated.

Note: This upgrade should not impact manual document imaging and scanning during the maintenance window.

Scheduled Interface Downtime – MQ Upgrade
Investigating - S Situation

The interfaces will be temporarily unavailable on November 3, 2026, from 2300–2359 (11:00 PM–11:59 PM) due to a scheduled MQ upgrade.


B Background

The MQ upgrade is a planned maintenance activity required to support system infrastructure and ensure continued interface functionality and performance.

All Cerner applications (PowerChart, Revenue Cycle, FirstNet, SurgiNet, etc.) will be available during this event.


A Assessment

During the maintenance window, interface communication with Cerner will be interrupted. Systems and applications dependent on these interfaces may experience delays or temporary disruptions in sending and receiving data.
Patients can still be registered in the Cerner system.
No other non-Cerner downstream systems will be updated during this event.


R Recommendation

Utilize downtime procedures for non-Cerner downstream systems. Contact the HELP desk (573-884-4357) for any issues during the downtime.

Please plan accordingly and communicate this scheduled downtime to all impacted departments and stakeholders

Nurse Call notifications not going to ASCOM / TigerConnect
Resolved - We have been monitoring for >24 hours and are confident the nurse call alerting to ASCOM / TigerConnect issue is resolved.
Oct 29, 13:59 CDT
Update - The virtualization software was restored around 1145 and we have been monitoring nurse call alerts going to ASCOM phones. TigerConnect should also be receiving messages as we show them connected on our side, but no code blue notifications have went off at our Columbia campus to validate TigerConnect functionality at this time.
Oct 28, 13:15 CDT
Update - Update, we have engaged our nurse call vendor as well as the virtualization software company to work thru re-licensing the software and ultimately re-enable nurse call events from nurse call to ASCOM / TigerConnect.
Oct 28, 09:01 CDT
Investigating - S. Nurse call notifications are not going to ASCOM phones or TigerConnect currently.

B. We use serial cable virtualization software to transmit nurse call events from a nurse call server to both the CareAware iBus and TigerConnect for secondary notifications. Primary notifications for the nurse call system occur at the console phones and staff terminals (where applicable) installed in each unit.

A. Windows patches applied to the nurse call servers has broken the virtualization software and we are reaching out to the vendor to resolve the current issue.

R. Please make sure staff are watching the staff consoles and staff terminals for the time being while we work to resolve the software issues impacting secondary alerting to ASCOM phones and TigerConnect.
