Alienware m17x R4 order shipping?

I waited 3 weeks (since august 4, estimated delivery date of aug 20, now 9 days overdue) for my m17x to ship because of a "part shortage". Finally I get an email from dell saying it has shipped. So i try and track the package but the UPS website wont recognize my tracking number, nor the Dell site!. Anyone have a clue when it may come? I live in Canada.
