Is Mendix Technology Down?

This incident has been resolved. --- [2026-11-06T11:23:53.810Z] (investigating) We are currently investigating this issue.

A fix has been released. Newly built apps on Mendix on Kubernetes and Mendix on Azure start normally again. If an environment failed to start, deploy the app to that environment again. This builds a new image that contains the fix. Restarting the environment is not enough, because a restart reuses the faulty image. Environments that kept running are not affected and do not need any action. You can deploy as usual again. If you pull the Mendix runtime base images through your own registry mirror, sync them again before you redeploy. --- [2026-11-05T09:45:18.708Z] (monitoring) A fix has been implemented and we are monitoring the results. --- [2026-11-05T08:10:56.364Z] (identified) We identified the root cause and prepared a fix. It is currently propagating through our release pipeline. --- [2026-11-05T08:03:59.899Z] (investigating) We are curently investigating the issue. Do not deploy or redeploy running environments until further notice. Restarting environments is safe. Do not downgrade the Operator, downgrading the Operator is unsupported an will not resolve the issue.

We will be undergoing scheduled maintenance during this time. --- [2026-11-04T09:58:31.028Z] (scheduled) Maintenance is scheduled for the application infrastructure of <b>Mendix Cloud</b>. The maintenance will improve the security and stability of the Mendix Cloud platform. We normally announce maintenance two weeks in advance. This time, we are making an exception and giving shorter notice. The patches in this maintenance contain critical security fixes for recently published vulnerabilities (CVEs), and we want to apply them as soon as possible, and before the holiday season begins, to keep your applications and data protected. We apologize for any inconvenience and appreciate your understanding. 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, Nov 10th, 2026, 08:00 UTC End: Tuesday, Nov 10th, 2026, 16:00 UTC <b>Impact on Mendix apps</b> During the maintenance, the Runtime Engines (application instances) of your Mendix applications will be restarted on the updated application infrastructure. This is executed automatically in no specific order. To ensure continuous availability for <b>all customer applications</b>, the underlying infrastructure upgrades will be performed in a rolling fashion. This means the rolling upgrade process ensures <b>no downtime</b> 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. <b>Moving early</b> 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 <b>Thursday, November 5th, 2026, 12:00 UTC.</b> Any application that is (re)deployed or restarted after this time will be scheduled on the updated infrastructure and <b>will not be restarted again during the maintenance window.</b> 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.

We will perform updates on our platform applications. During the maintenance window, several parts of the Mendix Portal as well as APIs may become temporarily unavailable. You may not be able to log in, view or deploy your applications during this time. Please retry your actions once the maintenance window has been completed.
