Well, i’ve put Orbus on the shelf due to this exact issue and 56+ posts in the crashes/lags/freezes/disconnect thread. I’ve provided countless log files and tested many things to no avail.
Since i put orbus away i have ofcourse played many other online games, with servers based various places around the world. Not once have i been disconnected or had a bad connection to any of these games. And prior to getting orbus in the first place, it has generally been the same.
I disconnect or suffer from a bad connection extremely rarely. When it does happen, it is almost always on the server end, and often a temporary problem that the insert-name game i am playing are aware of at the time. Outside of that, i may lose or suffer from a bad connection due to my ISP maybe 2-4 times in a year. Each time, i can also read why that has happened on my ISPs info pages. I have had the same ISP for about 10 years, so yes, i know it is almost 100% stable.
So no, as far as i am concerned it definetely does not point to being an EU thing.
