Be aware that a few of my long standing orders canceled today for no real legit reason. A DPAC agent told me this, "There was a mass cancelation of orders by the system. They are being reopened as soon as possible. Please watch your orders for orders to be reopened"
I have had several lines say that they are cancelled, but they still show in the backorder report page as pending. The news that I got was that they were working to reverse all cancellations. Time will tell I suppose.
