I made a user gadget that renders a chessboard for Property:P6648: https://www.wikidata.org/wiki/User:IagoQnsi/chessboard.js

Hmm, it actually seems like I can't reproduce this bug at all anymore, even without the beta feature enabled. I'm not sure what changed but I guess it's resolved. Thanks for taking a look!

Just trying to think up solutions - if thumbor gives a 429, could varnish instead send an (uncached) redirect to the original file [if not huge] or some standard size (like the size that would be on the image description page so is likely to already be rendered)

It seems like a graceful degredation where if we dont have a thumb just return a larger one and let the browser shrink it, is much preferable than a hard 429 failure. At least as long as the file isnt one of those 2gb nasa images.

{{Wikidata Infobox}} is transcluded 3,081,892 times on Commons. Currently, the template is completely failing, and the infobox contents are replaced with a "NO WIKIDATA ID FOUND!" error message. I'm going to set this to UBN.

Yes, this was on Wikimedia sites. I tested that list of passwords against en.wikipedia, but brief testing indicated that the list was the same on other Wikimedia wikis.
