error code 90,000

So, Since the last maintenance, which was on the 15th of November i believe, I have been receiving error code 90k, I keep getting disconnected from dungeons and regular game play. I am currently playing on ps3, and before this recent update my game play was fine, i would get occasional lag from time to time but nothing serious where i could not play the game. Now the game lags horribly and i ultimately just disconnect. I have checked my internet connecting and my signal is fine, so i know its not me. I really hope this issue is solved b/c i cannot play the game, and i will cancel my December subscription if its not solved, no point in paying, if i am unable to play the game.
