VM Unassignment Started events blowing up today - why?

Today I noticed a dramatic spike in Events.

Was not able to find an explanation for these event spikes, though I suspect stale VMs are suddenly being triggered to be released/cleaned up?

My title has builds with very low capacity (Dasv4 2 cores, 1 server per machine, 3 servers max).

Can somebody explain how to interpret what is happening here?

For clarification, this event multiplayer_server_vm_unassignment_started will be triggered when you set the number of the Target Standby Servers and the Maximum Servers to 0 for the server build, and the backend completed the handling. When you don’t actively using a server build, we would suggest you shut down the active servers and set the number of the Standby Servers and the Maximum Servers to 0. It’s a recommended way to reduce the usage time of the VM. When the number of the standby servers is greater than 0, the VM usage time will be calculated continuously. And finally, when the VM usage per month exceed the 750 free core hours, you will be billed for excess. Besides, this event may also be triggered when you delete the build or title.

Hi! saw this happening again on my build, I don't believe anyone set servers to 0 (is there a way to view history?)

I had standby/max servers set to 3/3 and clients weren't able to connect.

After deleting and redeploying servers things worked.
