As I understand it this is a much bigger issue than BB (all their games are down). It would seem that their internet provider has been hit by a DoS attack and those can take a long time to recover from.
This is why you're not seeing any information through the home page etc. BB have no ability to provide information because they have no internet connection. To be blunt it would seem that this incident is completely out of their control so no point having a pop at them.
