Issue just started occurring yesterday and has not let up. Our internet is 300+ mb/s. Have been playing FFXIV for years with no issues until yesterday. Tried restarting router, computer, switching back/forth data centers, tried using a VPN and tried all of the other fixes online which do not work. Internet is fine and 0 lag on any other programs/devices, only with FFXIV. Something is up with FFXIV specifically. Both computers we have are far above minimum system requirements.
