An Azure service that is used to provision Windows and Linux virtual machines.
In addition to the above himanshu response, we would like to highlight that this behavior is commonly observed when the Azure Portal encounters intermittent issues while fetching resource metadata from backend services. This does not impact the actual state or availability of the Virtual Machines.
Also, since the issue started after a couple of days without any configuration changes, it further indicates that this is likely a transient platform/UI issue rather than a misconfiguration on the subscription or resource level.
To further validate:
- If the VMs are accessible via Azure CLI / PowerShell
- Or visible under “All Resources”
then it confirms that the issue is isolated to the portal view rendering layer only.
