The Machine Learning team rolled out a change to most of the wikis (excluding fi, wikidata and en) that changes the backend service called by the ORES Extension code. This is part of a process to modernize our ML infrastructure, you can find more details here:

The main impact that users could have is getting weird results in Recent Changes filters (all the ones related to ORES, for example "User intent predictions" and "Contribution quality prediction"). So far the only issue was reported by the fiwiki's community, tracked in https://phabricator.wikimedia.org/T343308 (we are still investigating what happened). If you see anything out of the ordinary, feel free to contact the Machine Learning team:

Thanks in advance!
