This does not bode well to the quality of the product itself, the lack of basic skills and forethought is frightening. After all that "we know what we are doing" talk I guess we can now point and laugh.
They anticipated the launch issues so they brought on two distributors who have networks and infrastructure in place to distribute these sorts of products to customers all over the world.
The problem is (and judging by their website design) these distributors probably don't get that much traffic on a day to day basis. Their products seem very niche. The distributors were warned and this is what happens.
Don't blame the Raspberry Pi foundation for this.
