As Ghost stated, "Networking Issues" can be and is a big problem with accessing the game and also causes the lags. I've monitored with pings or tracerts to the server and I've monitored my own systems (PC's) while playing. If you notice, the game freezes, but the text messages do not. This isn't a sign of flyordies site failing. Its PC related. If it were the server, the text messages, while in a game would also freeze.
The networking aspect is simple....
There are many pieces of the puzzle between your PC and the server. Any one of which can be weak or slammed with traffic. Not only are you sending "0's" and "1's"(data)to flyordie, but in return, your getting the same back. Everyone may be taking a different route to the server which would explain why some have this problem and some don't.
As in driving a car, sometime ya hit a traffic jam,
sometimes you don't.
