It looks like fedorapeople.org is validated using dlv.isc.org, you might want to change this now that .org is signed: http://dnsviz.net/d/fedorapeople.org/dnssec/
However, it also looks like repos.fedorapeople.org is unsigned (http://dnsviz.net/d/repos.fedorapeople.org/dnssec/) if I am understanding this correctly, in fact it looks like all *.fedorapeople.org objects are unsigned, or something else is broken, which means that anyone validating using DNSSEC (and there aren't many of us) is unable to visit those pages.
I am a subscriber to the digest only so it may take me some time to reply unless you cc me.
