Is Umbraco Down?

We are canceling the 17.8.0 and 18.3.0 automatic upgrades that were planned for today. A potential breaking change has been found (issue: <https://github.com/umbraco/Umbraco-CMS/issues/24385>). It’s related to customers using Azure Managed Identity to connect to external databases. The upgrade will be available in the Cloud Portal for manual upgrades, so people can assess whether their sites are using the feature and upgrade if needed. A patch will be released this week, and automatic upgrades will pick it up from Tuesday next week. The 13.16.4 upgrade is rolling out as scheduled, as it’s not affected. --- [2026-11-03T08:00:01Z] (maintenance_in_progress) Maintenance has started --- [2026-10-29T14:57:05Z] (maintenance_scheduled) The following releases are being queued for Scheduled Upgrades on Umbraco Cloud: • Umbraco Cms 13.16.4, 17.8.0 and 18.3.0 Projects with automatic upgrades enabled will be upgraded to the matching version during their next selected upgrade window.

Maintenance has started --- [2026-10-19T08:24:53Z] (maintenance_scheduled) On Thursday 29-10-2026, between 09:00 and 17:00 CET (08:00–16:00 UTC), we'll carry out scheduled maintenance on the Umbraco Cloud platform services to improve their stability and security. **What we're doing** Infrastructure updates: Changes to the infrastructure behind the Umbraco Cloud services that keep the platform current and supportable. Security hardening: Configuration changes that strengthen the protection of the platform and your content. **What this means for you** No downtime is expected. Your websites are not affected, and the Umbraco Cloud Portal, deployments and other services will remain available throughout. You don't need to do anything. **How we'll look after the platform** We've scheduled this work during business hours so our full team is available throughout. We'll monitor the services during and after the maintenance, and if anything doesn't behave as expected, we'll deal with it right away. If you have any questions, contact our support team.

The issue has been resolved, and all affected Cloud sites in the West Europe region should now be available. If you are still experiencing issues, please contact our support team. --- [2026-10-27T16:32:36Z] (monitoring) Our infrastructure provider has applied a fix, and we are seeing affected Cloud sites recover. We are actively monitoring to ensure all sites are fully restored. --- [2026-10-27T15:39:04Z] (identified) We have identified the cause of the disruption. An issue with our infrastructure provider’s database service in the West Europe region is intermittently preventing some Cloud websites from connecting to their databases. Affected sites may show errors or be unavailable, and the Backoffice may also be affected. We are working with our provider to resolve this and are monitoring the situation closely. We will provide another update within the hour. --- [2026-10-27T15:13:35Z] (investigating) We are currently experiencing a service disruption, and a number of Cloud sites might be unavailable. Our team is working to identify the root cause and implement a solution. We will provide additional updates within the hour.
