Request: subdomain that times out when connected to via HTTPS, and subdomain that refuses HTTPS connection

[Pokechu22]

http://http.badssl.com/ currently responds to HTTPS with a redirect to the HTTP page. However, some sites do not support HTTPS at all, either refusing the connection (e.g. https://www.dkc-atlas.com instead of http://www.dkc-atlas.com) or timing out (e.g. https://www.metrorex.ro instead of http://www.metrorex.ro). There can be bugs that only occur when HTTPS is refused or timed out, such as this firefox bug.
