I've been playing the game since last April and had no issues with lag (outside of the DDoS situations). Suddenly on 5/17/2018 I now have permanent all day lag within FF14.

This lag is exclusive to the game. No changes were made on my end to the game or my PC. The lag is still here this morning and presumably is here to remain.

When checking my latency specifically within FF14, it jumps from 74 on average (in any other game) to well above 200. This isn't really a tolerable situation, so it must be resolved or I'll be getting refunded/chargebacked for my sub money and moving on to other games.
