Found in locations/regions appended by STG when running az vm list-skus --size "Standard_A" --resource-type "virtualMachines" --output table. Example SouthCentralUSSTG.
Not sure what does it mean. Is this a valid region to be used in azure location?
I have tried to list the all-region in azure i didn't found any region like STG AFAIK, it's not valid to use in azure
