Typically when outages happen, especially at this magnitude, some customers can request a root cause analysis report from the vendor, whether it be AT&T or RIM. These usually take up to 7 days to be researched and approved for distribution. I would say that there's a good chance you'll read about it in the news and/or on these forums from those who have access to request the root cause analysis.
