Cannot create App Service Plan in UK South — "Total VMs: 0" quota error, Microsoft.Web registered, vCPU quota confirmed

Lee Cunningham 20

I have been unable to create an App Service Plan in UK South for approximately 7 weeks. I originally worked around this by deploying to UK West, but I need to move to UK South to co-locate with my PostgreSQL Flexible Server which is already in that region.

Error received (portal and CLI):

Operation cannot be completed without additional quota.
Current Limit (Total VMs): 0
Current Usage: 0
Amount required for this deployment (Total VMs): 1
Minimum New Limit required: 1

What I have already tried:

Registering Microsoft.Web resource provider — status shows Registered
Increasing Regional vCPUs quota in UK South to 2 via Usage + Quotas — confirmed as 0 of 2
Creating via Azure Portal — fails with above error
Creating via Azure CLI — same error
Tried SKUs: F1, B1, S1 — all fail with identical error
Both Linux OS — all fail
Microsoft.Web does not appear in the Usage + Quotas provider dropdown so I cannot view or adjust App Service worker quota through the portal
Contacted @AzureSupport on X — directed to paid support

Subscription ID: [subscription ID available on request]

Region: UK South

Resource group: nudge-rg (already exists in UK South successfully)

CLI command attempted:

bash

az appservice plan create --name nudge-plan-uksouth --resource-group nudge-rg --location uksouth --sku B1 --is-linux

The vCPU quota increase appears to be for Microsoft.Compute rather than Microsoft.Web — I believe the actual blocker is an App Service worker pool quota that is not visible or adjustable through the standard portal UI. Any help getting this unblocked or escalated to the App Service team would be appreciated.

Hi Lee,

Please follow instructions below to see if you can increase your subscription's App Service quota.

In Azure portal, please navigate to Quotas using link below:

https://portal.azure.com/#view/Microsoft_Azure_Capacity/QuotaMenuBlade/~/overview

Next, please click on App Service (Public Preview).

At the top, click on the Region filter, change it so that the region you want (e.g. UK South) is selected.

At the bottom you should see your current App Service quotas and usage. On right, click on pencil (or person) icon next to the quota you would like to increase, for example, F1 VMs if you would like Free SKU, P0v4 for Premium P0v4, etc. Fill out the details on New Quota Request panel on right and click Submit.

Assuming your request is approved you can try deploying your app service again.

Please click Accept Answer and upvote if the above was helpful.

Thanks.

Hello, thanks you for the quick reply, I tried to up the quota, but it fails, so opened a support ticket for it. Just need to wait for that and hopefully they can unblock me.

Cheers

Hi @Lee Cunningham

Thank you for reaching us regarding the issue and thanks for @TP for providing your investigation

Please follow the below steps to raise quota request

Open the Azure Portal and go directly to the Quotas page using this link: Quotas - Microsoft Azure1. Click on App Service (Public Preview).
User's image

At the top, click the Region filter and select the region where you are trying to create the Web App (e.g., East US, Central India, etc.).
At the bottom of the page, you will see your current App Service quotas and usage. Locate the quota you want to increase (for example, F1 VMs for the Free SKU or P0v4 for the Premium P0v4 SKU), and click the edit (pencil) icon next to it. In the New Quota Request panel that opens on the right, provide the required details and click Submit. Once your quota increase request has been approved, try deploying your App Service again.

The error indicates a quota issue in the target region, not a problem with the CLI command or SKU selection. The vCPU increase performed for Microsoft.Compute does not affect App Service worker quotas for Microsoft.Web.

To unblock creation of the App Service plan in UK South, use one of these supported paths from the context:

Use the Quotas experience for App Service
- Open the Azure portal and go to the App Service quota self-service experience (Quota blade for App Service plans).
- From there, view current usage and limits across SKUs and request additional quota for the App Service plan in UK South.
- This is separate from the Microsoft.Compute vCPU quotas and specifically controls App Service worker capacity.
Open a support request for non-adjustable quotas
- Some quotas (including certain App Service worker quotas) are non-adjustable via the standard UI and require a support request.
- In the Azure portal:
  1. Search for “Quotas” and open Quotas.
  2. From Overview, select Compute (or the relevant quota category for the failing resource).
  3. Locate the quota that corresponds to the “Total VMs”/App Service worker capacity in UK South and select the support icon.
  4. In the New support request form, choose Quota type: Other Requests and provide details:
    - Region: UK South
    - Resource type: App Service plan / Microsoft.Web
    - Error text including “Current Limit (Total VMs): 0”
    - Requested new limit (at least 1, or more if needed).
  5. Submit the request so a support engineer can adjust the underlying quota.
If the portal quota blade does not load
- If the Quotas blade for the relevant provider fails to render (stuck loading), use the guidance from the similar case in the context: rely on CLI/REST to inspect quotas and open a support request while the portal issue is investigated.
- In this scenario, the support request is still the authoritative path to have the hidden or non-adjustable quota corrected for UK South.
Consider paired-region deployment only as a temporary workaround
- The context recommends using a paired region when a region has a quota of 0 instances and cannot create resources.
- However, since co-location with PostgreSQL in UK South is required, the permanent fix is to have the quota for App Service workers/“Total VMs” in UK South raised via the quota self-service experience or a support request.

Once the quota for App Service workers (or the “Total VMs” limit backing App Service in UK South) is increased above 0, the existing az appservice plan create command and the portal creation flow should succeed without changes.
