404 errors on /wp and /gh

I had to disable using Statically for my sites today because I noticed that some scripts that previously worked are now returning 404 on both the /gh and /wp endpoints. Examples (as of this post):
https://cdn.statically.io/wp/c/5.4.2/wp-includes/js/backbone.min.js
https://cdn.statically.io/gh/WordPress/WordPress/5.4.2/wp-admin/css/dashboard.min.css

Did something change?
