Question

Couldn't able to delete the custom domain and it stuck on deleting status forever

Srikanth Potharaju 0

We are trying to add a custom domain to one of our static web apps, but we haven't been able to do so. We keep getting validation failed for both CNAME and TXT records. When we tried to delete those records, it got stuck forever on deleting, then gave us "operation failed: unknown error"

We have tried deleting the custom domain from the CLI as well, but no luck it's failing from the CLI as well. Because the custom domain status is stuck in deleting forever, we couldn't even able to delete the static web app.

Hi,

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 just tested and was able to add custom domain this time. It took a little longer than normal to complete, but it worked.

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.
