We will be applying a patch to the database at 11:00pm MST Saturday March 2nd to address performance issues related to the Quiz Heuristics report and the Course Activity report. These report issues were also affecting other parts of the system causing broader performance issues. We expect the downtime to last between 15-30 minutes. This patch only affects the AWS North American server cluster.
