they sent out random emails for people to join the "closed" beta. The reason I say "closed" is because as a closed beta participant you can add up to 3 friends off your uplay friends list. It is not a true closed beta as they are just doing a smaller scale stress test. Also if it were a true closed beta there would be some requisites to be considered. Just another ploy by Ubisoft to make it seem like they are going to listen to the community.
