As a player on one of the largest EU servers, how is the current lag situation affecting you?

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.
