This happened to me and seems to have stopped now *crosses fingers* I tried two different PCs. Two different routers. Two different browsers. Two different IPs. Two different ISPs. Tried flushing DNS. Tried flushing browser cache. Tried different OS. etc etc etc. Could still connect from my phone on the cell network. Only thing I can think of is that the whole region was having trouble connecting or something. Oh, and I tried two different DNS servers. Only thing that stopped it was just waiting for it to work again.
