Hi @Scott Davis

1) From another similar question (https://learn.microsoft.com/en-us/answers/questions/692182/appserviceplancreateoperationisthrottled.html) brtrach-MSFT answered:

I wanted to follow up and verify that the 429 error occurs when you have too many deployments/failed deployments of an app service plan within a short period of time. This causes the system to throttle any additional deployments for the next 48 hours. This limit is per region, which is why you were able to use other regions or subscriptions.

If this occurs, you will need to wait 48 hours to complete a deployment in that region or contact support to see if they will remove the throttle.

Please let us know if there are further questions or concerns.

2) I recommend you raise a ticket with Azure support found at https://azure.microsoft.com/en-ca/support/create-ticket/ and see if they can assist.

Thanks for reaching here! To add further on DillonJS response, You may want to know that App Service Plans have a 10 per region limit on the Free SKU and 10 per resource group on Shared SKU and further limits according to SKU is listed here.

Depending on your plans you would need to either move to higher plan, or raise a support ticket to see if the limit can be raised you may also want to check the other limits in that link.
In case you don't feel you are hitting any limit then you would need to raise a support case.

Please let us know if issue persists.
