Nope, the game is still unplayable. I have connected at friends houses (who have Virgin, BT, etc) and barely any noticeable delay. I have tried using a different xbox, using different DNS servers, resetting the router before every game. I have even tried hotspotting my phone and playing on my mobile network - which, funnily enough, gave me a better experience at times.
I'm no network genius but there is clearly a jump from 30-40 ping to 100+ ping when the data passes through zayo - which appears to be part of the virgin network. That would suggest to me that there is an issue with where my data is being routed.
A response with regards to this particular issue would be fantastic
