If SI are not able to deliver the patch from the update URL hardwired into the game, then they should really set their servers to redirect to one of the mirrors or, at least, provide details of these mirrors on the update page.
The current message is extremely unhelpful, don't you think? It To me, it just suggests server load problems which will go away very soon but that is clearly not the case.
Not everyone who plays the game wants to have to register and then scour the forums for information ...
