Blackberry Interruption Due to Tech Upgrade

A major disruption to the BlackBerry email service Monday afternoon was caused by an internal data routing problem related to a recent technological upgrade, BlackBerry maker Research In Motion said today. The Waterloo, Ontario-based company said the upgrade was a long-term technology investment made to deal with increasing demand for its popular email service.
The upgrade caused intermittent service delays Monday afternoon, which lasted between 3:30 p.m. and 6:30 p.m. The company said no messages were lost and that the system operated smoothly all Tuesday.
Yesterday, the company didn't respond to inquiries about the outage but major carriers like AT&T and Sprint Nextel said they had heard from RIM. The carriers said the network problems affected BlackBerry users on all North American carriers.
It was the second time in a year that a technological upgrade at RIM caused a major breakdown in the service. Last April it was a software upgrade that caused the system to blitz for several hours overnight.
