The patch that introduced the bug was merged on

which, I think, means that it'd have been deployed on Thursday, 3rd
September – that's a long weekend's worth of data that we won't see again.
The deployment schedule is not quite that simple. If you open the 'Included
in' section of the breaking commit, you can see it was included in
wmf/1.26wmf21.
According to
https://www.mediawiki.org/wiki/MediaWiki_1.26/Roadmap that was
deployed to
mediawiki.org,
zero.wikimedia.org and some test wikis on the
1st, most wikis on the 2nd, and then only Wikipedias on the 3rd.
