Any other institutions experienced students submitting papers to Turnitin but their paper not being visible for days during the JANET issues? We have one report of a student submitting on the 4th December (received a digital receipt) but the tutor couldn't see it until this morning (11th Dec). The tutor had checked on the 10th December and the paper wasn't there so emailed the student, who then emailed her digital receipt as prove of submission on 4th Dec. I've reported it to Turnitin just in case they have noticed anything at their end.
We use the Turnitin building block integration with our Blackboard Oct 2014 release.
