Since 2019-03 (two issues ago), Tech News MassMessage delivery to he.wikipedia.org fails in wikitext.
- In wikitext in Hebrew if the target is not on he.wikipedia.org (example from Hebrew Wikisource)
- On he.wikipedia.org if the target is a Flow page (example)
- For surrounding entries on the target list if they are not on he.wikipedia.org
See https://meta.wikimedia.org/wiki/Global_message_delivery/Targets/Tech_ambassadors for the target list.
See https://meta.wikimedia.org/wiki/Talk:Tech/News/2019/03#A_bot_problem for the initial report.
I have only done a manual check of other targets for 2019-04, but they have all been successful deliveries. Theoretically this could be part of a larger problem and I just haven't found the other unsuccessful deliveries, but then I've been very unlucky.
