FFXIV ARR is 3 this year, Server upgrades?

[Delmontyb]

So with that 3 year mark advancing upon us, I wondered about server upgrades for FFXIV. With increasing network bandwidth and better server hardware, how many of the limitations we hear of might be overcome?

Contrary to popular belief, but server upgrades are always happening. Hardware breaks down, get's replaced, sometimes even the whole setup gets replaced as well. That's all depends on the network architecture that they are using.

More or less what you are referring to is a re-write of the server code that runs the game, to take advantage of any new hardware updates that have been made along the way.

I could see that happening every once in a while, but I'm only guessing with no knowledge of the code base.
