I don't know if my post will help but ...
I am located in Europe, specifically in France. And yesterday before the server update, I had around 20% of rejects, since the update things are alot better.
ATM i've got one 1,120kh/s rig, so almost 1,1MH, perfect beta-test rig.

I've totally normal reject ratio, so it's possible to join and make profits with this pool even if you're european.
In this rig i've two card: one r9 280x with intensity of 13 and one 5870 with I=17.
Finally, i would like to thank Terk who did an outstanding job, is aware of the priorities and help us to make good profits.
