I specifically did not post a link to the cert download site  because I don't

The OLD CA was destroyed it no longer exists.  because we were not issuing 
certificates correctly and were unable to revoke them.

I don't personally know  each and every fedora contributor.  but if anyone 
wants me to call them to verify that they need new certs I am more than 
willing to call each and every person.  However  if you don't replace the 
certs you will not have access to cvs or the buildsystem.  they are using only 
the new certs and checking the crl. 

you can verify the new cert and host key hashes at  
https://admin.fedoraproject.org/fingerprints  of course you have to trust that 
that is valid and that the whole fedora infrastructure has not been spoofed.
