Now I've noticed quite a few posts saying that people can't connect and when they manage to do it gets disconnected and brings up the dreaded error code. Now, it has nothing to do with your internet connection for one and there is nothing wrong with your disk. Europe experienced the exact same problem for about a week. Some people could try for like an hour and not get on others (like myself) could get on quite easily for a short period. Nintendo will adapt the server to meet demand but everyone has to be patient which I know is difficult but believe me it will get sorted out very soon.
