I'm a bit confused by this task.
There is a browser test which fails when no cards show (see https://integration.wikimedia.org/ci/view/Reading-Web/job/selenium-daily-beta-RelatedArticles/332/)

@Jdlrobson thanks, I should have looked more closely at jenkins before creating this task. Could someone verify that it actually failed between May 28 and June 2 (jenkins history is too short but hopefully a mail was sent to someone)?

Found https://lists.wikimedia.org/pipermail/qa-alerts/2019-May/date.html#start and https://lists.wikimedia.org/pipermail/qa-alerts/2019-June/date.html#start and indeed the browser test properly failed 6 times consecutively.
I'll start monitoring this particular job but Is there something we can do so that we take actions when it happens again in the future?

The beta cluster job runs daily, so I guess if anything is being touched that might impact the morelike API, it's best to merge that after a branch cut and verify those tests are continuing to work correctly. Our team should be monitoring those too (https://www.mediawiki.org/w/index.php?title=Reading/Web/Chores) although it looks like we missed on this occasion possibly due to some noise on our failing Minerva build (cc @phuedx), You can test the morelike API on https://en.m.wikipedia.beta.wmflabs.org/wiki/Baby_chicks as well.

Thanks, we will try to be more cautious on this feature in the future, if there is anything else we can collectively do to improve this I am happy to help otherwise please feel free to close this task as Invalid.
