VM Shutdown unexpectedly and didnot restart automatically either

HI ,

My VM deployment id :71683c255ddf45fd84c67f0b9101a261

I noticed that my VM got shutdown unexpectedly on Sep 1st 2013 . And the worst is that it didn't restart automatically either. I had to manually start the VM .

The event log had only the entry with timestamp when i manually restarted and it said ,

Source : Kernel-power
Event ID : 41
Task category : (63)
Description :
The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly

Can somebody explain what might be the reason ? I am starting to doubt if Windows Azure is ready for full deployment yet.
