Horrible [Diabolos] World Lag

I don't know if this lag i'm experiencing is interconnected between the home world DIABOLOS or not. But [obviously] I play on the world DIABOLOS. At the beginning no lag. Once i join a queue for AK (Amdapor Keep); the entire time i'm doing the dungeon i am lagging horribly. Receiving: 0.

Anyone else?

Can't be client side.

EDIT: Re logged. World Diabolos is lagging for me.

I find a lot less lag when I make a party in diabolos and go on the dungeon with all diabolos memebers but maybe it was lucky of me when I use duty finder I almost always start lagging on weekends

I haven't noticed much playing off Diabolos... but I usually go into AK with a pre-made, which may support what PrinceKite was saying?
