Is Umbraco Down?

**Update: today's automatic upgrade to Umbraco CMS 17.6.0 has been cancelled.** We've found a breaking change in 17.6.0 that can leave a site in a broken state after upgrading, so we're holding the rollout. The issue stems from the UUI library, which was updated in this release. Sites running Umbraco Commerce below version 17.1.11 are known to be affected, but other packages depending on UUI may be impacted as well. Details on the Commerce issue and how to resolve it: <https://github.com/umbraco/Umbraco.Commerce.Issues/issues/868> We're preparing a patch, and that version will be the next one rolled out automatically on Umbraco Cloud. We're currently aiming for 17.6.1 next Tuesday. --- [2026-08-11T06:00:00Z] (maintenance_in_progress) Maintenance has started --- [2026-08-06T13:40:21Z] (maintenance_scheduled) Umbraco Cms 17.6.0 and 18.1.0 has been released and will automatically be upgraded on projects running 17.x, and 18.x and have automatic minor upgrades enabled. Release notes can be found here: <https://releases.umbraco.com/release/umbraco/Umbraco-CMS/17.6.0> <https://releases.umbraco.com/release/umbraco/Umbraco-CMS/18.1.0>

This incident is now resolved. The issue affected a small number of projects during automatic upgrades, where an upgrade could become stuck without completing. Around 2.7% of attempted upgrades were affected, and some of these completed successfully despite showing as stuck. We have added new monitoring to detect this behaviour earlier, and a fix is being rolled out ahead of the next round of automatic upgrades. If you believe your environment was affected, or an upgrade appears stuck in future, please reach out to our support team and we will resolve it for you. We apologise for any inconvenience caused. --- [2026-07-29T12:33:31Z] (identified) We have identified the cause of the increased number of hanging automatic upgrades. An issue in our upgrade orchestration can cause an upgrade to become stuck without receiving a completion status. Affected upgrades do not fail, but their activity may continue running and the environment can report as busy for other operations. As a short-term measure, our support team can cancel stuck upgrade activities to unblock affected environments. If your environment appears busy or an upgrade seems stuck, please reach out to support and we will resolve it for you. A fix that handles these cases more gracefully is ready and is expected to be rolled out within the coming week. We will post a further update once it is deployed. --- [2026-07-29T12:33:03Z] (investigating) Some customers may experience hanging upgrades on their Umbraco Cloud projects.

The issue has been resolved. --- [2026-06-03T13:09:31Z] (monitoring) The issue has been resolved. --- [2026-06-03T10:41:44Z] (monitoring) Deployments in the **UK South** region are now completing normally. We're monitoring closely to confirm this remains stable and to understand the underlying cause. If you experienced a failed or timed-out deployment earlier, please retry it now. We'll confirm resolution shortly. --- [2026-06-03T09:27:32Z] (investigating) We're currently investigating an issue affecting deployments for projects hosted in the **UK South** region. During this time, deployments may time out or fail to complete. Live websites are not affected and remain online. This is limited to the CI/CD pipeline. Our team is actively working to identify the cause and restore normal deployment performance. We'll post a further update shortly.
