One of our server on Azure was shutdown around 9:27 am 2023/9/14.

We checked 'Resource health' and we got 3 health event as attachement.

We checked this VM and It is not windows OS of VM issue.

Could you please confirme what's happen about it?

It is our production environment and it could be shutdown.![User's image](/api/attachments/fdfe390b-5b17-4d50-9db1-f3a5b3103089?platform=QnA)

    Sorry to hear that your Virtual Machine was taken offline unexpectedly. From the image you have attached I can see the cause was due to "unexpected failure on the host server".

    Azure does its best to prevent these failures, but they can and do occur. For critical and production infrastructure we recommend using redundancy and expect failures to occur.

    Unexpected downtime is when the hardware or the physical infrastructure for the virtual machine encounters an issue and fails unexpectedly. Issues can include local network failures, local disk failures, or other rack level failures. When detected, the Azure platform automatically migrates (heals) your virtual machine to a healthy physical machine in the same data center. During the healing procedure, virtual machines experience downtime (reboot) and in some cases loss of the temporary drive. The attached OS and data disks are always preserved.

    Virtual machines can also experience downtime in the unlikely event of an outage or disaster that affects an entire data center, or even an entire region. For these scenarios, Azure provides protection options including availability zones and paired regions.

    Hope this helps clarify. Let me know if you have any questions or concerns.
