Impact / Notes
A large spike - around 600 - of these on kowiki several hours after 1.36.0-wmf.3 deploy.
Reproducible at the given URL. Not clear that it's creating user-facing breakage, and I'm reluctant to block the train over the weekend for this, but I'll probably roll back if it crops up at any volume again.
