Today I encountered a strange error in connection with the CAA that I’ve never seen before.
But before I’ll give a description of the impacts, I’m going to start with the chronological background story of the problem:
Another editor tried to upload (additional) images to a release and I wanted to vote on them, but they could not be viewed in any size. After I had told them that their edits look empty, they tried to upload them again – with the same result. I couldn’t believe this and started my own attempt to upload one of these pictures – and failed too 
This is what happens: After “successfully” uploading the image with the AJAX uploader, the resulting edit shows the usual We are unable to display history for this cover art. For a current listing of cover art, please see the release’s cover art page.
So far nothing special… but when I visit the cover art art page, usually it’s only the thumbnail links that are not working shortly after the upload. This time I also get a Page not found error for the original link!
Looking directly at the files on the IA server, there’s only an older upload, but no trace of the new images or any of the failed attempts.
The issue seems specific to the release, because other recent CA uploads can be displayed just fine. Has anyone ever experienced similar issues with the CAA and/or is able to explain this? The only similar ticket I found is CAA-119.
