Static Web App custom domain stuck in "Deleting" status — all delete attempts fail (CLI, ARM, Portal)

Static Web App custom domain stuck in "Deleting" status — all delete attempts fail (CLI, ARM, Portal)

Riccardo 45

I have an Azure Static Web App (Free tier) with a custom domain stuck in a broken state that I cannot clear through any self-service method.

Resources:

Static Web App: yoga-website-static, resource group rg-yoga-website-app-compute, region East US 2
Custom domain: www.altroveyoga.com (CNAME validation)
Subscription: "yoga-project" (happy to share the subscription ID by private message)

What happened:

Added the custom domain via az staticwebapp hostname set. DNS validation succeeded immediately, but the "Create" operation itself failed ~10 minutes later with a generic error: "An unknown error has occurred while adding your custom domain. Please try again later."
Since then, every attempt to delete the failed custom domain entry — so I could retry adding it — has itself failed, across every method available:
- az staticwebapp hostname delete (CLI) — failed
  - Direct ARM az resource delete on the customDomains sub-resource — failed
    - Azure Portal UI (Static Web App → Custom domains → Delete) — failed twice, with the Portal showing "Impossibile eliminare il dominio personalizzato www.altroveyoga.com. Errore: Failed"
      - Removed the CNAME record at the DNS provider entirely, waited ~45 minutes for propagation, retried the delete — still failed the same way
      1. Checked for resource locks on both the resource group and the Static Web App itself — none exist.
      2. The custom domain resource has now sat in "status": "Deleting" continuously since the first failed create, over 2.5 hours ago.

Activity Log timeline (all events on the .../staticSites/yoga-website-static/customDomains/www.altroveyoga.com sub-resource):

Time (UTC)	Operation	Result
06:34:06	Validate Custom Domain	Succeeded
--------	--------	--------
06:34:06	Validate Custom Domain	Succeeded
06:34:08 → 06:44:11	Create Custom Domain	Failed
06:44:52 → 06:54:53	Delete Custom Domain	Failed
07:06:23 → 07:16:27	Delete Custom Domain (direct ARM)	Failed
07:27:34 → 07:37:35	Delete Custom Domain (Portal)	Failed
07:57:02 → 08:07:11	Delete Custom Domain (Portal)	Failed
08:33:08	Create Custom Domain	Succeeded
08:33:14	Create Custom Domain	Succeeded (again?)
08:33:20 → 08:43:24	Delete Custom Domain	Failed
08:46:02 → 08:56:06	Delete Custom Domain	Failed
09:05:56 → (pending/failed)	Delete Custom Domain (CLI)	Failed

Every "Delete" fails roughly 10 minutes after being accepted, with no more specific error surfaced than "Failed."

What I need: I don't need to preserve anything about this custom domain entry — I'd just like the stuck resource fully released so I can add www.altroveyoga.com to this Static Web App again from a clean state. Based on a similar thread I found (Static Web App custom domain stuck in "Deleting" — cannot remove), this looks like a backend synchronization issue that needed direct engineering intervention rather than anything fixable from my side. Any help clearing this would be much appreciated.I have an Azure Static Web App (Free tier) with a custom domain stuck in a broken state that I cannot clear through any self-service method.

Hi Riccardo,

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 tested and was able to add custom domain this time. It took a little longer than normal to finish, 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.

Hi TP, hi Venkatesan,

Thank you both for the update — really appreciate you following up on this.

Confirming it's resolved on my end: I was able to successfully delete the stuck www.altroveyoga.com custom domain entry and then add it back cleanly — it completed in a few minutes instead of hanging the way it had been all day. The domain is now correctly bound and serving over HTTPS.

Thanks again for the transparency on the root cause and for following up directly — really appreciated, especially given this had no clean self-service fix on our end while the incident was active.

Best, Riccardo
