If you want to get ready to play as soon as Final Fantasy XIV: A Realm Reborn's servers come back up with patch 3.15 and its intake of new Anima-driven content the download is now available.

The patch is pretty light, weighing about 90 megabytes (92.16 on PC).

While the download is now available, the servers aren't open yet. They will in a little over an hour, at 3 AM PST.
