Ah yeah, that could well be the case.

We should drop that from dns. It was only used when we were moving from
phx2 to iad2. There should be 3 things in dns:

bastion01.fedoraproject.org
bastion02.fedoraproject.org
bastion.fedoraproject.org

with the last one being a CNAME for whichever one is default
(currently 01).

Anyhow, the ssh access SOP should be updated with all this info. 

Probibly sshfp isn't worth doing these days and we should just stick
with the certificate signed config.
