Do you know the dungeon solo in FFXIV

FFXIV  is my  favorite game.  I start to the game recently. The map in the game world is so huge that I easily lose my way.

I read about the dungeon solo in http://www.ffxivarrstore.com/news/2--ffxiv-arr-is-the-only-dungeon-solo . But I want to know more informaion about the dungeon solo. Do you know abut it?
