We have spotted the issue, it seems like a deliberate attempt that was done yesterday to cause an issue. It has been plugged and shouldn't repeat.
Deepsat, trade execution/charting/ will happen on Pi itself, no NEST will be involved at your side. The execution management will still be at the Omnesys end, but they are probably the best among what we have for this in India.
We are also in the process of completely replacing our entire server setup (which is between 3 to 1 years old). This should happen by Sept 20th.
