PowerSchool Service Interruption

On Tuesday, June 14, 2011 from 7:45 AM until 8:45 AM PowerSchool was unavailable.  The application encountered an error and hung while it was shutting down.  When the application was brought back up, a security setting had been changed to allow only 2 concurrent logins.  This setting was corrected, the PowerSchool application was restarted, and service was restored.
