The shell server, “fedora.eskimo.com“, is back online, now as Fedora 22. There are still some operations in progress like the conversion of the yum database to dnf, the new package handler [Probably stands for D)oes N)ot F)unction].
I really hate it when developers make major changes to what was a good functional system. Anyway it is what it is. Those of you wanting to get a look at Fedora 22, there it is.
