Our guild is experiencing horrible instance lag every Tuesday evening from around 530-730PST on the Uldum realm. Other guilds are also complaining about it in general chat. No one is having any issues with their latency or FPS, this is just affecting us while in Castle Nathria at certain times. It seems to come in waves, sometimes with delays as much as 2-3 seconds while everyone’s ping and and fps are showing normal. It has lasted for hours before. This is crippling our progression and wasting our time, and we would very much like it to be resolved.
