[atlas]Probe flapping

Hi Aftab,

Although your probe is located in Asia, it is still connected to one of our controller in Europe because this part of Asia is closer to Germany than west coast of US :)
Since Friday our system is fully functional, so I think it's your network that makes your probe flapping. The small gap is normal since after the probe disconnects it takes some time to re-connect.
From what i can see from our history your probe was disconnected quit often from the beginning :)


Regards,
Andreas Strikos
