There's been severe lag and disconnect (90K) issues since 16:00 GMT on Leviathan. That's six hours. The lag was intermittent and noticeable for me as I was gathering and unable to log the trees, just standing there like a fool. At round 20:00 the first disconnect occurred (I had been logged in but not playing due to the lag) and I've not been able to get back in since. Shame as this is the first time I've had to play properly since last weekend.
