The 1.35.0-wmf.34 version of MediaWiki is blocked[0].
The new version is deployed to group0[1], however, canary checks failed during the deployment of wmf.34 to group1 wikis and was rolled back. The train can proceed no further until this issue is resolved:
Exception from TermStoreWriterFactory : Local entity source does not have items. https://phabricator.wikimedia.org/T253804
Once resolved, the train can resume. If resolved on Friday, the train will resume Monday.
Thanks for your help in resolving the issue.
