Issues like the 2 navtiming downtimes I caused this week could have been prevented if we would have been able to notice their effect on group1 wikis.
Taking a quick look, we don't collect enough navtiming data on those wikis and they have no data at night, but we can try oversampling them:
SELECT wiki, hour, COUNT(*) FROM event.navigationtiming WHERE year = 2019 AND month = 4 AND day = 11 AND wiki IN ('cawiki', 'hewiki') GROUP BY wiki, hour;
