This.
You are by far not alone, a LOT of people are suffering from constant latency issues, making the game more or less unplayable, and the problem is at SE's hands, or rather their CA data centers.
This problem has lasted for soon two weeks, and for many its getting worse as time goes by.
At the moment 1.0 servers where a lot more stable which is realy sad considering 2.0 would have new server structure and all that.
