Have been able to reproduce it (or better my bot):
18-12 00:00 UTC / 19-12 00:00 UTC / 21-12 12:00 UTC / 23-12 00:00 UTC / 26-12 12:00 UTC / 27-12 12:00 UTC / 28-12 00:00 UTC / 28-12 12:00 UTC / 31-12 12:00 UTC / 01-01 12:00 UTC / 02-01 00:00 UTC
So it seems there is some datapolution on 1 or a few database servers that provide the triples for the Wikidata Query Service. And it doesn't look like it will be solved automatically.
A full reimport is in progress and should solve this issue once completed (or if it does not, then we'll need to dig deeper). Reimport has started last week and is likely to run for another week. It then needs to be propagated to all servers...
Thanks for the update. I'll check if it still occurs after the reimport is finished.
Full reimport is in progress. By the look of it, it will still take around a week to catch up on lag on wdqs1010 before we can copy the data over to other servers.
This should be fixed by latest data reload (T252068). Feelf ree to reopen if that's not the case.
