This latency is permanent and not just during peak gaming hours.
It's impossible to play Fifa 17 online, I've spoken to EA Games and XBOX support and exhausted all their procedures and tests, leaving it down to the IPS. Please find above a ping test which shows how bad the latency is. The best and worst times should have no larger difference that 100ms. I haven't shown the Host name or IP Address.
I have tried contacting Virgin Media a number of times and it seems as my phone call goes to get answered the person hangs up?
