Snapshots are run regularly which normally update Blackboard with information about instructor assignments and students enrollments.
Around 8am, Sunday May 20, we had a bad run of those snapshots which returned no information from Oasis. This lack of Oasis data was then processed, which resulted in all Summer instructor and student assignments disabled in Blackboard. This was identified and corrected by 10am Sunday.
No student data was lost as a result of this error. All student submissions entered prior to the error are back online along with Blackboard access.
