Hosted Mender Outage History

Some users get an "An error occured." message when they open Deployments > Finished. It happens on smaller screens and in browser windows that aren't maximized. We have found the cause, a display issue in the web interface, and are working on a fix. Devices, deployments and the API are not affected: deployments keep running and finishing as normal. Workaround: Make the browser window wider, or zoom out (Ctrl/Cmd and -), until the page loads.

The latest release to hosted Mender on 2026-08-26T12:09Z introduced more optimized indexing of device inventory which had an unintended side effect of denying devices with array-type inventory data.

An upstream provider notified that they are experiencing elevated error accessing API on EU region. It's possible that the Mender devices are unable to pull artifacts and deployments might fail. We're monitoring the upstream incident status.

We've identified a regression affecting users who access Mender with a custom role (rather than the built-in administrator role). As a result, we have rolled back to the previous version. When a user with a custom role attempts to list software when creating a deployment, the request is rejected with There was an error while listing software forbidden by role-based access control Only users assigned a custom role were affected. Users with the built-in admin role were not affected. We apologize sincerely for this issue.

The issue has been identified and a fix is being implemented

We rolled back to the old green cluster, still having the same issue.

We identified an issue with an upstream cloud provider. Unfortunately, even our statuspage was affected and we could not open this status page before now. Among the issues, we identified: * issues reaching the hosted Mender API server * emails not being sent * UI login not possible. The incident started at about 07:50 UTC

The cloud provider is fixing their issues, we can see that most of the hosted Mender services are back to full operation. We're continuing to monitor the issue. The email service is still not working.

We are aware of an open incident with a Cloud Provider for the Artifacts Storage for both hosted Mender US and EU. You may experience slow artifact download or throttling. We're monitoring the upstream provider's status.

The issue has been identified and we're working on a solution.

We identified an issue regarding the Server-side generation of Delta Artifacts feature; the generation starts and reports success but the silently fails in the background. We are working on a fix.
