When I compare the following two commands

(shell)$ curl --ipv4 --verbose http://ftpmirror.your.org/pub/wikimedia/dumps/ (shell)$ curl --ipv6 --verbose http://ftpmirror.your.org/pub/wikimedia/dumps/

The first reports "HTTP/1.1 301 Moved Permanently" The second reports "HTTP/1.1 200 OK"

Has anyone else noticed this?

I don't see that. (but I also never compared them before)

See below.
