has aleph.sagemath.org disappeared?
In my school we run a Moodle site. The opening page in my math course downloads two scripts from aleph.sagemath.org. The scripts were useful in the past when I displayed a few sage-cells, which have been removed later. The references to these scripts however were only visible in the page source and were not removed.
Now it seems the server at aleph.sagemath.org is unreachable, and the page hangs when trying to contact it. I'm unable to view it, and unable to edit it. Is this a temporary problem or has this server disappeared for good? Any suggestions on how to repair the situation?
