Authenticator sold out, still no word on Canadian security

According to the writer of the isheepthings blog, the Blizzard Authenticator, after about two and a half days on sale, is listed on the Blizzard store as sold out. This all happened with no Canadian being able to order one themselves unless they had a US shipping address. There are those who advise that Canadians go and order from the European store, but to my knowledge the Authenticator was never available from there, only showing Sold Out for the entire duration.

[Update: Blizzard has now posted both about the sell out and the lack of availability to Canadians. Thank you Blizzard for answering the questions I and others had.]
