Software glitch caused BlackBerry outage

  • Toronto (Canada) - Research in Motion says it recent BlackBerry outage was caused by a server-side software glitch.  The company was trying to upgrade the server cache, but apparently didn’t test the software thoroughly.  The company stresses that this was the only cause of the outage and that the scalability and security are functionally normally.

    The software upgrade was supposed to improve email storage, but eventually caused a cascading failure between the BlackBerry database and cache. Engineers desperately tried to move operations to a backup system, but that also failed.

    The outage caused eight million BlackBerry users to miss their emails.  Users were also unable to send any messages.  Sevice was eventually restored Wednesday April 18th.
