As one of the larger EU servers, how are you affected by the lag issues? And will/has Tuesday's patch made a difference?

Since the "fix" that was supposedly to rectify the situation (I was on holiday during 1.3 patch launch, and just getting back in the game now). I was in Denova last night. It was not pleasant. We had three major lag spikes on Kephess, the last boss, the largest spikehit for about 2-3 seconds which wasn't welcome. We also had one disconnect during the encounter.
