A loading error appeared on some of the lecture videos for some of the courses this morning. The first error occurred at 23:22 on 02/05/2023. We confirm that it had been fixed at 16:45 on 03/05/2023. The error was due to a system update by our video-hosting third-party platform. It is the first major error that has been recorded since April 2022.

This error only affected 14.26% of the videos we have on the platform, mainly lecture videos. The student’s homework, video feedback, and grading system were unaffected.

We are extremely sorry for any inconvenience caused to you during this interruption.
