If i delete a topic on mediawiki.org, i still see this topic (and all deleted answers), if i open the thread in another (private) tab where i'mnot logged in. This shouldn't be possible, if i delete a topic, it should be deleted and all caches should be purged.
Sidenote: If i run action=purge as a not logged in user, the topic appears as deleted.
This essentially sounds like the varnish cache isn't clearing all related pages. We have a hook called getSquidURLS or something like that that likely needs to be updated.
