The openSUSE servers seems to be running a SOPA blackout protest on its own. The servers are down and users can't download the distro or software packages from the build service.

The SAN array of the backend server server seems to have lost 3 hard disk at once now :/ That means the array is broken atm. We can not fix this before monday. Since not all binary parts of the projects are in backup it means that we will need to rebuild some of them afterwards. Sources and project configurations shall not be affected by this. It is sunshine out there, have fun :)
