None of these are found in the `event.mediawiki_revision_create` hive table.
I can't find them in the `eqiad.mediawiki.revision-create` topic either
* For Q968274 at 2131311442: the revision-create event failed to be emitted with `Unable to deliver all events: 503: Service Unavailable`: https://logstash.wikimedia.org/app/discover#/doc/logstash-*/logstash-mediawiki-1-7.0.0-1-2024.04.17?id=MjA17I4BWjhRzdxne8ai.
I can't find traces of the other three but searching for "Unable to deliver all events: 503: Service Unavailable" in logstash I can huge spikes of failures (sometimes more than 20k in one hour):
{F47519706}
It is possible that mediawiki or event-gate failed to properly submits these revision-create events.
