That seems to be an inaccurate title, on the account of a misplaced comma: "Apple Admits iTunes Download Cloud Error, Restricting Some Content Downloads" seems to mean "Apple admits that there is an error, and in response is restricting downloads"; you probably meant "Apple Admits iTunes Download Cloud Error Restricting Some Content Downloads" - "Apple admits there is an error which is the cause of restricting downloads". The story itself is interesting, though.
