A custom domain on our Static Web App has been stuck in Deleting and cannot be deleted or re-added. This looks like the same platform-side wedge reported in question 5940933, which was resolved by a mitigation applied by Microsoft. Requesting the same mitigation on this resource.

  • Resource: worldskyguide (Static Web App, Standard plan), resource group worldskyguide_group, Central US
  • Default hostname: white-water-0060a7c10.7.azurestaticapps.net
  • Affected hostname: www.worldskyguide.com, CreatedOn 2026-08-11T21:54:43Z
  • Status: Deleting
  • Error from az staticwebapp hostname list: "An unknown error has occurred while adding your custom domain. Please try again later."

The hostname never provisioned successfully on add, TLS completed but the site returned no HTTP response. Delete has failed three times since: twice from the portal, each taking roughly 14 minutes to fail, and once via az staticwebapp hostname delete. The DNS CNAME has been removed, so no DNS record is competing with the operation. A second custom domain on the same resource, staging.worldskyguide.com, is Ready and serving normally.

    Hi Katie,

    Can you retry deleting your custom domain now? I just retried mine and it successfully deleted after about 2-3 minutes. Previously it had been stuck for many hours.

    Also, I was able to successfully ADD custom domain. Took a little longer than normal, but I can view my static site via custom domain now.

    Below is latest update from the Service issue DZXC-65Z:

    Service: Static Web Apps

    Region: Global

    Event tags: --

    Impact Statement: Starting at 14:30 UTC on 11 August 2026, you have been identified as an affected customer using Azure Static Web Apps in multiple regions who may experience failures or delays when deleting custom domains for resources hosted in the region. At this time, the impact is limited to a subset of customers.

    Current Status: Our teams have completed mitigation actions and are currently monitoring recovery progress. The issue was attributed to a backlog in the job queue responsible for custom domain deletion operations, which caused deployment requests to time out. Mitigation efforts included reducing the batch size of operations and stopping specific operations to accelerate queue recovery. Current telemetry indicates that the queue backlog is decreasing rapidly and is expected to reach a healthy state shortly.

    Initial assessments indicate that custom domain creation and update workflows remain healthy, with the impact limited to delayed or failed custom domain deletion requests while the backlog was present.

    We are validating recovery by monitoring system performance and confirming successful retries from affected customers.

    The next update will be provided in 02 hours, or as events warrant.

    Thanks.

    -TP
