When deploying MediaWiki 1.35.0-wmf.18 to Group 2 wikis on Thursday, there was a serious incident which took down all wikis for several minutes and resulted in a rollback to wmf.16.
My current understanding is that attempting to deploy wmf.18 again is likely to cause another severe outage. The train remains blocked until the root cause of the outage is identified. Investigation is ongoing. Details and further updates will be posted on the status tracking task for wmf.18[1] and some background on the investigation has been documented in the incident report[2].
