Well the lag began in anger at 18.51 UK time on the server today. It seemed a bit slow, but manageable until that point. And now we're back to the 30+ seconds on various channels again. Can you seriously look at your logs about this and work out what on Norrath is going.
I'm pretty sure several european players are considering to stop playing due to the lag problems on AB. If Daybreak doesn't resolve this issue it won't take long before raiding on AB is dead.
