I've gone forward with 1.30.0-wmf.12 on all wikis except for Wikidata due to the ongoing issues mentioned previously. Wikidatawiki remains at 1.30.0-wmf.11 (with wikidata extension at wmf.10)

Due to today's train deployment more than doubling the error rate seen in fatalmonitor[1], I have rolled-back group 1 wikis to wmf.11. I've submitted an UBN task T172320 [2] detailing the error, which appears to be fallout from issues in Wikibase first noticed two weeks ago.
I expect that this will be easily resolved once someone familiar with the issue has had a chance to look into it and the train should be back on track in time for tomorrow's deployment.
