There is a further update on this issue, which can be found from this blog post from 01 February.

Following investigations, we can confirm that no recordings have been lost, and all are in the system as usual. Students are able to access published recordings as normal, and have not lost access to playback.

We are currently working to restore staff access to their folders as soon as possible, ensuring that current teaching is prioritised.

We understand that some recordings need to be edited prior to being made available, which is why we have the 48-hour delay in publishing recordings. If you need to access your recordings to edit them during this window and currently cannot access them, please email digital-education@bristol.ac.uk. Please provide the unit code, your username, and the details of the lecture you need access to most urgently, so that we can help as quickly as possible. Thank you for your help with this.

Permissions will be reset using the data we have available via timetabling and unit information in the University systems. If we have previously granted permissions to those who are not unit directors or owners in the system, we may need to do this again.

We again apologise for any inconvenience this has caused.
