Disconnect Issues

Hey, i was just wondering if there are actual servers issues causing disconnection or if its a network problem. I often get disconnect, oh well just reconnect. However this time, i was trying to break my score record so i was at half a million points and the server dc so i lost my streak. Kind of a pain. Lets say i was at some 2.5 million and the server disconnects and you lose it all. Just a bummer really
