+Packit downstream jobs may not work as expected due to the new _Anubis_ rules deployed in Fedora Infrastructure.
+For example, sometimes Packit gets back an HTML page with the _Anubis_ disclaimer instead of the specfile or the packit yaml config.
+Waiting and retriggering a job could work around the issue.
