My memory is still afresh with the news..Black berry outage affects Europe, Middle East & Africa. Now, time has come to north america.
Again, details are yet to known and coincidentally today is the iOS5 upgrade day and many of my friends 'bricked' their iPhones :). Seems the Apple servers are overloaded and today may be a good day to look for some device called 'land line'

I'd think this could be due to the DC issue or their GRX peering issue. DC is in London (or Slough to be more specific), where by the largest peering point is @ Amsterdam.
Looking at the problem, I'd say this is more likely due to the DC issue as some of the large operators have direct links with RIM but the DC @ Slough is the single point which consolidates the traffic.

Hopefully the Engineers can make it up fast :)
