Burstable SKUs seem not to be available in new Subscriptions in Europe

Question

Until 2 weeks ago, we were able to create Azure Database for PostgreSQL flexible Server instances with the B1ms SKU with our customers in the "Germany West Central" region. Now our customers report that they cannot create the instances due to the following error:

Status: "RegionIsOfferRestricted"

Message: "Subscriptions are restricted from provisioning in this region. Please choose a different region. For exceptions to this rule please open a support request with Issue type of 'Service and subscription limits'. See https://review.learn.microsoft.com/en-us/azure/postgresql/flexible-server/how-to-request-quota-increase for more details."

Is this just temporary and if so, when will they be available again?

Hi @Kevin Kupski | Zweitag ,

Welcome to Microsoft Q&A Forum, thank you for posting your query here!

Please follow the instructions below. Your quota for the selected SKU in this location has been exceeded. To increase it, follow the steps provided. If you're unable to do so, contact Microsoft to raise a request

Subscription->Quota->Select your region->BS family->Increase it

Increase the value you want to: - If you are unable to do, when you are increasing, please follow below instructions to raise a support request with MS, as we might not have control to increase the quota below is the link

Hi Kevin Kupski | Zweitag,

Message: "Subscriptions are restricted from provisioning in this region.

After exploring on your issue, I found that the provisioning of Postgres SQL flexible servers with "Burstable" SKU tiers is not supported in Germany West Central region. Because I have tried to deploy it with "General purpose GP_Gen5_2" tier in the same Germany West Central region and it worked successfully as shown below.

az postgres server create -l "GermanyWestCentral" -g caronew -n tenewr -u roots -p xxxx --sku-name GP_Gen5_2

Note: Also, with "standard B1ms" burstable tier, you will be able to maintain maximum of 50 connections only. I would recommend you use general purpose tiers to enable maximum user for Postgres SQL server. And also, it is possible that the specific region is not having sufficient quota to increase the limits. I would suggest you use other available regions to create a Postgres SQL server with standard sku tiers and proceed further.

Alternatively, by referring to this MSDoc for resolving capacity errors, the reason for the above error is due to the specific subscription did not have privileges to create and enable a server in the specific region (Germany West Central). For this, you can raise a region support request accordingly. You can follow the above given MS Doc process to raise a support request for that region enablement.

Also, check here for the supported or available regions to create a Postgres SQL server according to the required workload. It is clearly given that only (v3/v4/v5) Intel vchores are supported in Germany West Central region but standard tier only has v1 chores capacity. Refer MSDoc for the relevant information.

And also, for few kinds of Azure subscriptions like student or startup subscriptions etc..there will be a few limitations in deploying the services in few regions. Refer this Blog to understand the complete information on German Data center cloud.

Hope this helps.
