Try to do a bit of debugging as to why the EventLogging ExternalLinksChange doesn't work as expected.
To speed up debugging we need to be able to rapidly push changes to a local copy of the [[ https://gerrit.wikimedia.org/r/#/projects/mediawiki/extensions/SpamBlacklist,dashboards/default | spam blacklist extension ]] (logging to file etc.) and do controlled testing on a MediaWiki install. Obviously we can't do this with the production extension and we don't want to continue testing on the production test.wikipedia.
Therefore, we could try:
- [[https://www.mediawiki.org/wiki/MediaWiki-Vagrant|A local MediaWiki-Vagrant install]]
- [[https://wikitech.wikimedia.org/wiki/Analytics/EventLogging/TestingOnBetaCluster|Mucking around with the beta cluster deployment whatsit]]
- [[https://phabricator.wikimedia.org/T76375|Create a labs project dedicated to rapid debugging]]
Once testing, throw findings up on [[https://wikitech.wikimedia.org/wiki/User:Samtar/Why_isn%27t_ExternalLinksChange_working|this wikitech page]] and discuss with T115119
