a lot of pages are answering with a 403.
Such as : http://readme.drone.io/setup/overview : those links are in the sidebar.
this is because
http://readme.drone.io/setup/overview no longer exists. It is being served from your browser cache, and the links in the cached page’s sidebar no longer exist either. Unfortunately amazon s3 has very aggressive caching policies which causes issues whenever we make major updates to the documentation.
the 0.4 docs were moved to the following url
the best way to resolve this is to purge your browser cache for readme.drone.io or browse the site with developer tools open and the disable cache button checked. Eventually we’ll move away from S3 to avoid this problem, but it is not an immediate priority.
