Looks like this is related to https://gerrit.wikimedia.org/r/c/operations/mediawiki-config/+/763779/ (T302081)

From IRC:

20:35:27 cscott but if for some reason this did escape and something important ended up with the wrong URL endpoint, this config change is perfectly safe to revert

brennen subscribed.Mar 17 2022, 9:42 PM

https://gerrit.wikimedia.org/r/c/operations/mediawiki-config/+/771707 will revert the original change

My bad on formatting the revert commit - should have just used this task id.

Looks like it wasn't related so we'll unrevert.
