So I found yesterday that the MultiViews option was active in the
template used by cfgmgmt for those vhosts, and was the root cause of
that behaviour.
I confirm that such .raw image wasn't even present on those
cloud.centos.org, but httpd served the .raw.tar.gz instead.
Fix for this was pushed earlier today so you'll now have a 404 if you
try to download that .raw file again.
That brings though another question : why trying specifically to
download a .raw file that isn't listed on that page ?
