There are no fixes. There are no workarounds. Just keep trying.
Our clients/games/connections worked fine 3 days ago. Nothing on our end has changed to such a degree that they would cause problems to this extent. The only thing that has changed are the amount of people playing/trying to log/etc etc.
They dont have enough datacenters. They have the most populated servers on one datacenter so if you're on Aether you're doubly screwed; hence why you have such an easy time connecting to other data centers or the JP servers.
Sorry folks, but this is no different than the initial launch of the game. Things will calm down in a couple weeks. Sooner if they split the data centers in half.
