We are testing Azure right now with a RDG/RDS setup with 5 VMs right now. We noticed that one of the VMs has reported 1 hour of no activity in the monitor at 11 PM CEST on 07/07/2013 (in case any one else felt it) on anything (network, CPU usage, storage = all nothing), while all the other VMs reported to be fine and the VM itself even did stuff. It's the DC which holds all the FSMO roles, and stuff was happening in the hour "it was down" and nothing reports error, so we are pretty sure it wasn't down even though noone actively checked it in that time.
Just wondering if this is to be expected, since we want to use the built-in monitoring in Azure. If not, what can be done to fix/alleviate this?
