The External Tool configuration when using Turnitin in ICON is unavailable and not working at this time.  As a result, a Page Error notice is displayed that says "Something broke unexpectedly..."  Access continues to work when logging in at Turnitin.com.  

A work around for this, when creating new assignments in ICON, is to use the Plagiarism Framework configuration to work with SpeedGrader.  The instructions for this process are available at:  Creating an assignment in Feedback Studio using Canvas Plagiarism Framework

Support staff are working with Turnitin Support to clarify and resolve the situation.
