We have provisioned an AKS cluster in the East US region. It is stopped / started using an Automation Account each evening to reduce costs as it's a Development environment only. This is the second time in the past week that we have been unable to start it due to limited availability of D*v4/5 servers.
It will take a considerable effort to move the RGs, VNETs, Subnets, Cluster and storage to a new region (with no guarantee that we won't run into the same problem). I was hoping to be able to ask Azure Technical staff a direct question, but I've been sent here to a public Q&A for support.
My question is - what servers are actually available in East US (General Purpose - D series) that aren't going to cause my AKS cluster to fail again. I have tried D4as_v4, D4as_v5. What servers are actually available in the East US region?

Hello, @Pete Raleigh ! I'd be happy to provide some general guidance to VM availability and will reach out to you directly. For anyone else who may be running into this issue, SKU not available is a good place to start:
To determine which SKUs are available in a location or zone, use the az vm list-skus command:
az vm list-skus --location centralus --size Standard_D --all --output table
That command only lists the SKUs that can run there, but not how many are available. I can do the same within Azure when provisioning a server, and filtering on the region, subscription, etc.
So it's not very helpful when looking at available resources.

Hello, @Pete Raleigh !
I'm having trouble deploying Dv4 and Dv5 VMs in the East US region. What VM SKUs are available?
Dv4 and Dv5 VMs in the East US region are currently experiencing high demand. We would recommend looking at Dv6 VMs in that region.
Very helpful information. I was able to deploy a new nodepool (and delete the others I had tried - but which had also failed) and reconciled the AKS cluster. All up and running again. Thank you!
Happy to help!
