Would you be opening to setting an A record in the DNS? I could then make sure the redirect is working properly while we work through updating all the links.
I am not going to give you my login. I can add an A record if you like. There is already an A record that points to a IP address that resolves to https://shortener.secureserver.net
I just need the name, IP address, and TTL. The nuttx.apache.org URL and variants don't work. It asks for an actual IP address.
