App Service Plan Create operation is throttled (429) while creating a new Web App using Azure for Students subscription.

Question

I am using an Azure for Students subscription.

I am trying to create a new Linux App Service (Python 3.12, F1 Free plan), but the creation fails every time with the following error:

Error Code: 429

Message:

"App Service Plan Create operation is throttled for subscription. Please contact support if the issue persists."

I have already:

• Deleted previous App Services and Resource Groups.
• Tried creating a new Resource Group.
• Retried multiple times.
• Selected the F1 Free plan.

Please check my subscription and remove the throttling or advise how I can create a new App Service.

Hello @HARSH

Thank you for reaching out Microsoft Q&A.

https://learn.microsoft.com/en-us/azure/azure-resource-manager/management/request-limits-and-throttling

The limits might be smaller for free or trial customers.

Official documentation - Same as above.

In your scenario 429 error might have occurred as you might tried too many deployments/failed deployments of an app service plan within a short period of time. We suggest you to wait for some time till the refill operation fills the bucket according to token bucket algorithm.

Answer 2

As per https://learn.microsoft.com/en-us/answers/questions/692182/app-service-plan-create-operation-is-throttled

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 choose another region.
