Update: RIM this morning released a statement regarding the outage:
A service interruption occurred Tuesday that affected BlackBerry customers in the Americas. Message delivery was delayed or intermittent during the service interruption. Phone service and SMS services on BlackBerry smartphones were unaffected. Root cause is currently under review, but based on preliminary analysis, it currently appears that the issue stemmed from a flaw in two recently released versions of BlackBerry Messenger (versions 126.96.36.199 and 188.8.131.52) that caused an unanticipated database issue within the BlackBerry infrastructure. RIM has taken corrective action to restore service.
RIM has also provided a new version of BlackBerry Messenger (version 184.108.40.206) and is encouraging anyone who downloaded or upgraded BlackBerry Messenger since December 14th to upgrade to this latest version which resolves the issue. RIM continues to monitor its systems to maintain normal service levels and apologizes for any inconvenience to customers.
