We’ve run into some issues.,, iThenticate, SimCheck, Similarity and Originality are currently experiencing an unexpected service degradation. Users accessing the service via an integration may also be affected.

During this time, you may find that Similarity Reports are slow to generate, and logging in to Turnitin via Google SSO, will result in error.

We invite you to track the progress of this disruption while we work to bring the service back to optimum health.
