Thread:VisualEditor/Feedback/Seems to have a very big bug on fr.Wiki that could cause lots of damage. VERY FAST ACTION NEEDED/reply (3)

IRC would be that place, either #mediawiki-parsoid or #mediawiki-visualeditor. It only took 10 minutes for Parsoid devs to know about this, and (AFAIK) there isn't a real emergency switch (well, devs will try to revert the broken deployment, but that can go wrong as well, unfortunately). I personally checked all the edits made during that time on fr.wp (and it.wp) and reverted those which were not noticed by patrollers, and my colleagues did the same for other wikis. We did that in the past, and will do it in the future if similar emergencies arise. Thanks.
