MySQL Flexible Server ProvisionNotSupportedForRegion in UK South on sponsored subscription

Srinivasan Arumugam 0

we are building a non-production Azure foundation in UK South under a sponsored nonprofit subscription. A Terraform deployment attempted to create Azure Database for MySQL Flexible Server and Azure returned ProvisionNotSupportedForRegion.

[Removed PII Information]

Azure response: Provisioning in requested region is not supported. Your subscription might not have access to create a server in the selected region.

The Microsoft.DBforMySQL provider is registered, UK South is advertised for flexibleServers, and the server name availability check succeeds. Subscription-scoped capability and SKU queries return InternalServerError; [Removed PII information]. No failed MySQL resource remains.

Please confirm whether MySQL Flexible Server provisioning can be enabled for this subscription in UK South. If B_Standard_B1ms or zone 1 is unavailable, please identify a supported low-cost non-production SKU and zone in UK South. We want to preserve UK data residency and avoid a cross-region database design. This blocks a development migration but is not a production outage.

Hi,

A response of 500 InternalServerError when calling Location Based Capability Set - Get means that your subscription is blocked from provisioning in that region (UK South in this case). Due to capacity limitations a large number of subscriptions have been blocked from deploying MySQL Flexible Server to the most popular regions (UK South is one).

One thing you try is to create a free Service and subscription limits (quotas) request and request access to and/or increase your MySQL Flexible quota for UK South region.

To start the process, please click link below:

https://portal.azure.com/#create/Microsoft.Support

Issue type: Service and subscription limits (quotas)

Quota type: Azure Database for MySQL Flexible Server

Click Next

On Additional details tab, click Enter details. Select Region access or Quota increase, select region, select other details as needed, Save. Continue filling out Additional details tab, click Next, review and Create the case. You should receive automated email within minutes.

If you want you can check different regions to see if the region is blocked. Click link above, click Try It button, sign in, select your Tenant. Fill out as below:

capabilitySetName: default

locationName: uksouth

Scroll down and click Run button.

If you see response code 200 and Body box contains list of SKUs/Features, you know you have access to the region. If you see response code 500 and Body box has InternalServerError, you know you don't have access to the region.

You may repeat the above test for different regions by changing the location and clicking Run again.
