CRITICAL (for 5d 8h 23m 54s)
I don't understand what needs to be done from the linked doc: https://wikitech.wikimedia.org/wiki/Application_servers#Apache_setup_checklist
The runbook should probably be improved.
A quick search shows: T82798 but the file mentioned in the Gerrit CR doesn't seem to exist anymore. (that's also why I CCed @Dzahn )
Bryan pointed me to this depool from @MoritzMuehlenhoff - https://tools.wmflabs.org/sal/log/AWu4jHBdOwpQ-3Pkztx-
