UPDATE: This again appears to be another strong DDos attack. We are working hard to overcome it and will update when possible. It's currently 2am in Japan so please forgive us if our Facebook/Twitter updates are not as quick, though the team is certainly not taking any breaks. We're very much looking forward to implementing a much stronger solution very soon and will make an announcement to that effect once it's in place.
