Hello. When I tried to download Emacs for windows from http://ftpmirror.gnu.org/emacs/ it redirected me to a nonexistent mirror at https://www.gutscheinrausch.de/gnu/emacs/windows/. The actual mirror is located at https://www.gutscheinrausch.de/mirror/gnu/windows/emacs/.
That being said, I don't understand why the mirror is located on a commercial site in the first place. Cheers.
