RIM CTO David Yach responded to questions during a press conference this afternoon, explaining the original cause of the outage (that UK server failure, along with a series of failed redundancies), and how that grew into the global outage we're experiencing now:
The obvious solution would be to clear the backlog and restore service, but in doing so, RIM would purge any undelivered messages. Yach said that all emails will eventually be delivered, however, so you shouldn't have anything to worry about there (there was no related comment regarding BBM messages). When asked what the company would be doing to "make right" by way of its customers, Yach emphasized that his focus was only on restoring service at this point, and made no promises of restitution.
"It's a backlog issue. Clearly we have a backlog in Europe, based on the initial outage and the time it's taken to stabilize that. At this point, we have not throttled the other regions, but as you can imagine, with the global reach of BlackBerry, people using it to contact others around the world, there's a lot of messages coming to Europe from Asia and the Americas, and those would be backed up on the other system. It's looking like over time that backlog built, and started impacting those other systems."
