Hello all!
This morning at 8:30 UTC I merged a configuration cleanup on kartotherian configuration [1]. This ended up creating issue with geoshapes returning HTTP 400. The feature does not see much use yet and was only identified at 9:40 UTC. Rollback of the change was done at 9:57 UTC [2]. A slight increase in HTTP 400 on maps servers can be observed during this time frame [3].
The underlying issue is being investigated on T153188 [4].
Very sorry for the inconvenience...
Guillaume
