Out of sudden, no longer able to deploy more azure functions

Question

Since sth like 2 day on new subscription I face issue where when executing ARM template deploying bunch of Azure Functions + additional stuff I'm smacked with following issue:

• after successfully deploying sth like 10 Azure functions in consumption plan deployment hangs on hosting plan deployment with following details:
  {
  "status": "Failed",
  "error": {
  "code": "429",
  "message": "App Service Plan Create operation is throttled for subscription <sub_id>. Please contact support if issue persists.",
  "details": [
  {
  "message": "App Service Plan Create operation is throttled for subscription <sub_id>. Please contact support if issue persists."
  },
  {
  "code": "429"
  },
  {}
  ]
  }
  }
• 1st time i let it run in this state for over 12h with no help
• since then no longer able to deploy Azure functions to given resource group (even from portal)
• switched region and resource group and same situation repeated after deploying ~10 azure functions
• coming back a day later to same region/resource group combo yields no resolution to the issue

Most frustrating thing in this situation is that that very same ARM template was used in the past numerous times and it had no such problems. Has anything changed recently? All clues on how to mitigate this situation much appreciated.

Answer 1

App Service Plans have a 10 per region limit on the Free SKU as documented here. If you are using the free plan and need more than 10 plans, you would need to either move to a paid plan, or raise a support ticket to see if the limit can be raised (I suspect not on the free plan).
If your not using the free plan then check the other limits in that link, if you don't feel you are hitting any then you would need to raise a support case. Billing cases are free.

Answer 2

Subscription is Pay-As-You-Go... as stated I've deployed very same template multiple times in the past without the any problem
