The shutdown of the openSUSE Mirror will take place on 1 May 2019.
The SCC has discovered that the openSUSE mirror for updating generates more external network traffic than it really spares. Also, the update has been disrupted for some time.
If you have used the openSUSE mirror (ftp.scc.kit.edu/pub/opensuse) of the SCC so far, you should switch to the official mirror proxy: https://download.opensuse.org/
