It will be great to see a feature that will enable DNP administrator to limit the Maximum Bandwidth of the website when the site exceeds his bandwidth quota limit (Same as "stop website" feature in schedule tasks).
In this way, the customer will not be upset because his site was down. Instead of, he will ask us why the site is slow.
I think it's more elegant than stopping the customer website and it will be a unique feature.
I don't think it is hard to implement.
