Per MnSCU System Office:

D2L Document Viewer

We made some adjustments to our environment that appear to have alleviated the document viewer issue.  We are still closely monitoring the viewer queue, and would appreciate your prompt reports if users experience the spinning “loading” icon when trying to view documents in Content or Dropbox.

D2L Email and Notification Delays

We also made some changes for email, and continue to monitor the email queue.  This issue is still under investigation.  If you experience delays, please report via the ticket system with details of the time the email was sent or notification alert occurred, and when the email  was actually received.

Thanks for your patience on these issues.
