There are about 15 people online on my server so the servers are working the problem is making a stable connection to the servers. My advice is try try try and try again until you get lucky enough to get on. Feedback from those of us online on S4. Most seem to have logged in via 101xp portal on chrome with 2 logging in through facebook portal on chrome and 1 player logged in with firefox. I hope this in some way helps and please remember the player mods are not responsible so please lets not make a bad situation worse.
