[atlas]Probe flapping

Hi Aftab,

No it's not possible to change the controller your probe is connected to. The system is choosing the best controller for your probe based on the geolocation and some additional criteria.
I guess you can see the ip of the controller your probe is connected to. It's not a secret :)

Regards,
Andreas
