Mirroring codecs?

What is the best way to have a private mirror for codecs.fedoraproject.org? It’s referenced by EPEL for openh264. The host doesn’t respond to rsync. It doesn’t seem to be part of any of the mirror list that I can find. I’m mirroring codecs.fedoraproject.org with wget --mirror but it’s slow and inefficient. I’d much rather use a more elegant tool like rsync if possible.

For context, we’re developing retrogrid.io, a temporal mirror of Operating System history. Think: mirror + wayback machine + Vault + administrator support.

Thank you for your service!
