RIM experienced a second outage in less than a week yesterday and into today. Like last Thursday, users experienced email messaging delays. RIM has issued a statement that indicates that flaws in two recent versions of BlackBerry Messenger were responsible.
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 5.0.0.55 and 5.0.0.56) 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 5.0.0.57) 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.
As of this morning, it appears that RIM has resolved the issue. If/when things are working for you again, be sure to upgrade to BlackBerry Messenger version 5.0.0.57. It is available from blackberry.com/messenger or from BlackBerry App World.
