When you move into a zone and it's too busy a new instance is created therefore reducing the burden on the servers. This worked flawlessly for people on Legion release.
The problem with FF14 is that it uses very poor server organisation. They, as far as I know, keep everyone on the same instance so you can only get in so many, which is odd considering each zone is instanced, and not seamless like WoW.
SE really need to get their act together and write proper server code. Sadly the Achilles Heal of this game (2.x+) has always been it's poor, limited server code.
