Is there an issue with container instance creation in AustraliaEast starting as of yesterday?

Question

Hi,

I have a customer's container and registry in the Australia East region, and until yesterday (after months of working) we were provisioning an image based on mcr.microsoft.com/dotnet/framework/runtime:4.8-windowsservercore-ltsc2019, with the properties below.

Before asking this, I also tried CPU and memory of 2 each based on the updated values provided on https://learn.microsoft.com/en-us/azure/container-instances/container-instances-region-availability (which must have downgraded the capabilities since we deployed this because 4-CPU and 4-Ram was working) but we were getting the same error as below. Can someone shed some light on this as we need this container to be created every 2 hours to run an integration I don't want to continue to be throwing up instances on East US given the data transfer and data transfer cost as the container registry is still in Australia East.

Error:
The requested resource is not available in the location 'australiaeast' at this moment. Please retry with a different resource request or in another location. Resource requested: '2' CPU '2' GB memory 'Windows Server 2019 - Before 2B' OS

}
}

Azure Support on Twitter gave us a free support case... Basically the base windows/.net image we were using was too old (there are before2b and after2b images... The beforeb2 images are being retired/lessened capacity as anything before2b had a security hole, therefore everyone must transition base images to one using an after 2b image (list the cached images on azure to see what I mean about before/after 2b.
