Is there a wiki page where we can find name servers concerned by the
website (and which task they are doing)?
Sijis, I think that you where answering at this question last time
when my alias was down... I didn't get any answer ;-)
I thought i did answered you question. It took me to find it but its all here [1].
You may not have access to the server but jumping onto #fedora-admin or #fedora-websites, someone would have access there and double-check that everything on those servers are acting properly.
