That's because the network is overloaded at half-time with everyone checking their phones. It'll be like that throughout the Wolves match, as people will be constantly trying to check the other scores.
So there's no wi-fi and no mobile web access at the Amex, how are we going to keep up with what's happening elsewhere? Anyone got an old transistor radio? (perhaps this should be posted in the 'match days when you were young' thread!)
