Maintenance is scheduled for the application infrastructure of Mendix Cloud. The maintenance will improve the security and stability of the Mendix Cloud platform. This upgrade is executed on a platform level, which means there is no flexibility in the time period, but you can move your app early yourself (see below). An 8-hour maintenance window is planned.
Start: Tuesday, Jan 13th, 2026, 08:00 UTC End: Tuesday, Jan 13th, 2026, 16:00 UTC
Impact on Mendix apps
The maintenance will be executed only for the Mendix application deployed to the Kubernetes infrastructure. To find the Mendix application infrastructure, go to Apps and check the Infrastructure label on your environment. The label will contain either Cloud Foundry or Kubernetes.
During the maintenance, the Runtime Engines (application instances) of your Mendix applications will be restarted and redeployed to the an updated application infrastructure. This is executed automatically in no specific order. To ensure continuous availability for all customer applications, the underlying infrastructure upgrades will be performed in a rolling fashion. This means the rolling upgrade process ensures no downtime for both multi-instance applications (by restarting only one Runtime Engine at a time) and single-instance applications.
While the rolling nature of these upgrades is designed to minimize impact, a small number of users might experience brief, intermittent networking disruptions or 502 errors as underlying services are rotated. These are typically temporary and self-correcting.
Moving early
If the scheduled maintenance window is inconvenient for your application, you may opt to move to the updated infrastructure ahead of time. The updated application infrastructure will be available starting Thursday, Jan 8th, 2026, 12:00 UTC.
Any application that is (re)deployed or restarted after this time will be scheduled on the updated infrastructure and will not be restarted again during the maintenance window on Jan 15th. This allows you to control the timing of the restart and avoid impact during business-critical hours.
Please note that, even when moving early, a small number of users may still experience brief, intermittent 502 errors during the scheduled maintenance window due to the rotation of underlying platform services. These events are expected to be temporary and self-correcting.
