Users are advised to migrate workloads to supported operating system versions (e.g., Windows Server 2016/2019/2022) to ensure continued security compliance, support, and access to marketplace images.
Windows Server 2012 has reached end of support, and you need to verify if it's globally or regionally deprecated. please use Azure CLI or PowerShell to list available SKUs in a given region and confirm deprecation - https://learn.microsoft.com/en-us/azure/virtual-machines/deprecated-images
Provisioning and outages may affect Marketplace operations. Check Azure Service Health for any updates, especially for 'East US 2' - https://azure.status.microsoft/en-us/status
