In this week's delivery of Tech News, there were 2 problems.
- It sent 3 copies of the entire message to some pages, in multiple diffs across different minutes. E.g. https://cs.wikipedia.org/w/index.php?title=Diskuse_s_wikipedistou:Janbery&action=history and https://de.wikipedia.org/w/index.php?title=Wikipedia:Projektneuheiten/Tech_News&action=history
- But it didn't send at all to some other recipients (unless it's still going?). E.g. not sent to https://pt.wikipedia.org/w/index.php?title=Usu%C3%A1rio_Discuss%C3%A3o:Jaideraf&action=history and https://id.wikipedia.org/w/index.php?title=Wikipedia:Warung_Kopi_(Teknis)&action=history
The full target list was meant to be https://meta.wikimedia.org/wiki/Global_message_delivery/Targets/Tech_ambassadors
I definitely only clicked "Submit" once, so it's not an impatient user-error!
I'll tag this with WMF-JobQueue, which I suspect is related, in case that helps.
