I uploaded 11 cover art images to http://musicbrainz.org/release/1b00bda1-3d6a-41c2-a9f7-dc0afa278b91/cover-art . That was over 3 hours ago. The cover art list has 11 empty spaces for my images, and all say, "Image not available yet, please try again in a few minutes." Normally the thumbnails appear in just a minute or two.
The Internet Archive location for this Release seems to be https://archive.org/details/mbid-1b00bda1-3d6a-41c2-a9f7-dc0afa278b91 . I only see the one previous image there, not my 11 additions.
Is there a way I should diagnose this? How long should I wait until I decide the upload failed? Is there a good procedure for clearing out the failed uploads and try again?
I looked in the archive and web for relevant directions. I didn't see anything helpful.
When Internet Archive services are unavailable... talks about cover art not showing up when the Internet Archive is completely down. But cover art is appearing for other Releases I uploaded to in the same session. It sounds like a different problem.
Message "Image not available yet, please try again in a few minutes." does not go away appears to list several other upload failures, but doesn't give me hints about what to do when that happens.
Thanks in advance for your help.
