I got an email about scheduled maintenance for vm's not in an availability set and the vm was rebootet just like it would. I can verify this by checking the event logs of the virtual machine and the System log says
The operating system is shutting down at system time 2015-09-14T00:05:00.602526500Z.
and the next row is 15 minutes later
The operating system started at system time 2015-09-14T00:20:18.497268500Z.
When I open the Azure portal, go to could services and for this vm select "View Reboot logs" I can find absolutely no record of any reboot.
Why is this?
