(Now the whole of Wikitech is down.)

Wikitech is back up after(?) the wikitech servers had php7.2-fpm restarted.

Change 559112 had a related patch set uploaded (by Jforrester; owner: Jforrester):
[operations/mediawiki-config@master] Revert "train: Rolling Wikitech back to 1.35.0-wmf.10"

Change 559112 merged by jenkins-bot:
[operations/mediawiki-config@master] Revert "train: Rolling Wikitech back to 1.35.0-wmf.10"

https://gerrit.wikimedia.org/r/559112

Mentioned in SAL (#wikimedia-operations) [2019-12-18T15:58:45Z] <jforrester@deploy1001> rebuilt and synchronized wikiversions files: train: Rolling Wikitech foward to 1.35.0-wmf.11 T233859 T241059

Having re-rolled the train, all seems quiet. Without replication steps, I'm going to mark this as Resolved.
