I have been playing DCUO (online super-hero MMO) on the PS3 for about 10 or so months, mostly trouble free. About 1 month ago I started to experience extreme lag (I find myself three or four minutes behind everybody else - i.e I get a message that the boss is dead, but I haven't even reached that part of the fight) when in a raid (8 man group), and some open-world parts of alerts (4 man group).
At first I thought it was my PS3, so I replaced the hdd - this solved my rendering issue, but the lag persisted. I then suspected it was the actual game as a new DLC was released around the time I noticed the lag. Seeing as nobody else in my league is having problems, I started to look at my internet connection. speedtest.net is showing a ping of about 350 - 400ms from my PC to Amsterdam (where the EU DCUO servers are)....from memory that gave me a rating of "D"

So I started to poke around, and ran a trace route - results follow:

I like to think that I'm reasonably astute, but I have no idea how to read this, let alone work out if where the problem is likely to be occurring!
Any help would be greatly appreciated.
