EU servers for Xbox have now been down for nearly 5 hours, but the NA servers are still available from the UK. It might also be an idea to update the gamehub when stuff like this happens, as you obviously don't monitor it and people on there (who don't have access to these forums) are going absolutely NUTS because you appear to be ignoring them... although to be perfectly honest, it wouldn't surprise me if you were, because if it isn't PC NA you really don't seem to care that much...
