Update: It seems BlackBerry Internet Services are starting to work again in the affected regions. If they still haven't started working for you, try a 30 second battery pull and give it a shot.
RIM is very aware of the problem and is working to get it fixed as soon as possible, but as you all can imagine, maintaining and fixing a global network problem that expands over 3 continents is not as easy task. We'll keep you updated with any news we receive!
