I have been deploying AKS LTS 1.27 in EAST US for several months. However, this week my deployments started to fail. Only the system node pool is deployed. When I try and manually create an AKS cluster in the Portal I can no-longer select 1.27 as the version for AKS LTS in EAST US. I was able to select 1.27 in West US 2 - but then today that also stopped working. Now in EAST US and West US 2 I can only deploy AKS LTS 1.30.
Is this expected behavior? How can AKS LTS 1.27 be supported until June 2025 if I can no-longer deploy additional node pools without upgrading to AKS LTS 1.30.
Hello Stuart Rogers
Thank you for reaching out to the Microsoft Q&A platform.
I have reviewed with product team and there is an on-going issue limited to 2 scenarios:
Azure Portal add NodePool experience is broken for LTS
Terraform nodepool add experience is broken for LTS
While the product team is actively working to fix this for above 2 approaches, this can be workaround by directly using az cli or rest API. Thanks again for reporting the issue. I will keep a tab on this issue and post here once the issue is fixed.

Thank you for keeping us updated. Do you mind if I wait to "accept" the answer until the product team is able to resolve the issue?
Also thank you for providing the work around to use the az cli - I'm not sure how easy it will be for me to switch to this from my current workflow of using Terraform.

@Prrudram-MSFT We have noted that eastus, eastus2 removed 1.27 on 27Aug2024. Stuart Rogers switched to use westus2, but 1.27 disappeared from this region too on 29Aug2024. Is 1.27 being removed until this is resolved?

@Prrudram-MSFT Also is there a support track or some other mechanism we can follow to be informed on the status of this issue through resolution?
@Prrudram-MSFT Also is there some way we can follow the progress of these two issues through resolution?
Hello Heather Hewlett Stuart Rogers
AKS dev team is working on the fix. We don't have a public facing incident tracker for this. There is a Github thread that you can use to directly communicate with dev https://github.com/hashicorp/terraform-provider-azurerm/issues/27245
I will update this thread you can keep a tab on this please.
