Service Unavailable ??? !!!

As an old Siedlerfan I like the game as usual very good. The procedure is known and become the graphic grow. Online is not a problem for me. But now the shock. I want to play, signaling to me. And what I see on the screen: "Service not available .... try again later". Yes the spin of Ubisoft. I'm of the guys even punished because your server does not have the touch. So you can drive customers away.
