There was an error with uploading files, including Turnitin assignments, Moodle assignments and static files, since late Friday 15 March 2019. Users may have received the error message: 'unable to write to disk'.
The issue has been resolved as of 11:30am GMT, and students should be able to submit assignments as normal.
We apologise to the users that were effected, and we recommend the following:
Unfortunately some students may have been unable to submit their assignment during this period. Please try resubmit., and if you are unable to do so, please contact firstname.lastname@example.org with the course and assignment name, and a link to the course submission page.
If you had an assignment due over this period, please be aware that some of your students may have been unable to submit. To ensure your students can now submit, please ensure that late submissions are enabled, or re-open the assignment.
