Thank you for getting in touch.
I'm afraid that having a static IP address would mean the service is routing traffic differently to that of a dynamic IP address. 16ms ping is still a low latency result but this will be solely down to the difference in hops to the end address. If you don't need the static IP address for a specific reason for example IP cameras, SSH or file servers, I'm happy for you to remove it and we will refund you the one off £5 charge.
