What is the status of the Turnitin tools? Are they working normally?
Please see Turnitin's status page.
Because Feedback Studio, and other Turnitin tools, are not produced or maintained by D2L, Inc., the Turnitin tools' maintenance and upgrade calendars do not match those of D2L Brightspace.
In addition to visiting the status page, you may also track Turnitin system status by following @TurnitinStatus on Twitter.
