Blackboard has posted the following announcement regarding maintenance of their plagiarism detection utility: The SafeAssign service will be unavailable on Saturday, August 4th, 2012 from 12:01 AM US Eastern (GMT-4) to 9:00 AM US Eastern. SafeAssign is being taken offline for capacity expansion and proactive maintenance in preparation for the upcoming academic term. End-users will not be able to submit papers through SafeAssign during the planned downtime and will receive an error message if they attempt to do so. SafeAssign Originality Reports will not be available to Instructors or Students during the planned downtime, nor will instructors be able to access SafeAssign DirectSubmit. Please make end-users aware of these limitations. Use of SafeAssign can continue as normal after the planned downtime is complete.
