Description

A Djvu file that was replaced has inconsistent page thumbnails:

File description page: https://commons.wikimedia.org/w/index.php?title=File:Transactions_NZ_Institute_Volume_23.djvu&page=101

1024px shows the old image: https://upload.wikimedia.org/wikipedia/commons/thumb/d/de/Transactions_NZ_Institute_Volume_23.djvu/page101-1024px-Transactions_NZ_Institute_Volume_23.djvu.jpg
1023px shows the new image: https://upload.wikimedia.org/wikipedia/commons/thumb/d/de/Transactions_NZ_Institute_Volume_23.djvu/page101-1023px-Transactions_NZ_Institute_Volume_23.djvu.jpg

2021-09-16_094452_587x434_screenshot.png (434×587 px, 55 KB)

1024px is a number of note because it's the resolution used by the Wikisource viewer.

Several other pages in that file are showing the same thing.

This image has no persisted in some cache for a week (since the 16th Sept)

Krinkle updated the task description. (Show Details)Sep 23 2021, 9:18 PM

I suspect that the thumbnail is no longer in Swift, but still in CDN, since ?action=purge does not work on the file description page.

Krinkle moved this task from General to HTTP Cache on the MediaWiki-libs-BagOStuff board.Oct 12 2021, 6:52 PM

This particular file/page seems to have gotten unstuck, but was there anything done to do that?
