In the past couple of days, Petscan searches for en.wikipedia articles with no wikidata item have been returning articles that have wikidata items.
I think the issue may be higher than normal replication lag from production to labs databases - cf. https://tools.wmflabs.org/replag/ currently showing replags of up to 6 hours.
I use a consistent set of petscans on roughly a daily basis & have done for months & years. Current behavior - returning articles that have wikidata items - is not normal. Petscan is normally very reactive to changes made, such that one can run a petscan, create items for articles, and run the same petscan pretty much immediately and see the articles have disappeared from the list.
Grateful for any info or input on whether there is an issue here, and if so, a prognosis on likely time to fix. thx.
