Hello there!
5 years ago this post was created noticing that the artifacts hosting (gh.circle-artifacts.com) is not correctly configured for static website hosting, since it does not serve /0/index.html when pointing to /0/ or even /. There was a reply 2 years later without response.
3 years after the last activity in that topic, has there been any new developments in this regard? My team heavily relies on different statically-built websites and having this feature would greatly increase the value CircleCI brings to us.
