Newly, the data on [[Special:LanguageStats]] are no longer updated
The Special:LanguageStats_are_no_longer_updated_55750 highlighted comment was created in this revision.
We can no longer force it with "&action=purge" either, it just does nothing. I believe someone managed to force a purge yesterday (I got the "refreshing stats" message when viewing the stats) and since then it neither refreshes nor allows a purge.
I saw timeouts on our logs, so likely I should move that to the JobQueue.
Anyway, we should hunt down why it's not updating as it should.
