No artwork has been display for any cover art submitted in the past 20 hours.

The big issue is that the photos are not even shown even when you attempt to view through direct link to the CAA. (like usually when you enter new artwork in mb, the artwork might not show on the site for a little while, but you could always see it through the direct link at archive.org, in this case that is not possible). example:
https://coverartarchive.org/release/065e5f3a-23d0-4cbf-8289-8b3b14169149/23925133861.jpg
"cover image with id 23925133861 not found"

This could be a very significant issue as it does appear that these artwork submissions that have been "successfully uploaded" are gone, and nearly a whole days worth which I imagine is a few thousand.
