The instance runs on a compute node and should be unaffected. Traffic doesn't pass through the controller, with one exception: If the instance has no floating IP, packets it sends to addresses outside of the cloud (SNAT traffic) go through controllers.

Yes! existing network part in the VMs won't get affected. Since all the north-south traffic will go from the compute node to the internet and so are east-west traffic.
