I had some serious lag very late night EU times last night on Phinigel and Aradune. Had to log off, couldn't play. My friend i played with from Canada didn't have any problems. Could have been some EU > USA connection that was having issues. I don't know.
One of the ISP companies in Germany was having issues a while back, issues may have resurfaced again, either with them or a different one.
Had been seeing some minor lag the past few days but this morning the lag is very noticeable on Phinigel, from the UK anyway. Average ping is higher than usual too which would suggest a routing change.
