Hi,I think the email somehow didn't reach wikitech-l and some other mailing lists (except ambassadors)
The message did made it to wikitech-l:
I only got it via [wikibots-l] though. I suspect it is an issue with mailman which would prevent delivering the same messages multiple times even if it is dispatched to different mailing lists.
There is a bug filed https://gitlab.com/mailman/mailman/-/issues/914 which looks awkwardly close to the issue:
When a message is cross-posted and held on more than one list, handling the held post on one list will delete the held message from the message store. The held post is still in the held message view on the other list(s) and viewing, rejecting or discarding the post all behave reasonably, but accepting the post results in urllib.error.HTTPError: HTTP Error 500: {"title": "500 Internal Server Error"}
I have filed it as https://phabricator.wikimedia.org/T345691
, then I don't know anything about mailman, but it might be worth
looking at the server side logs.
