On SciPy's [topical software page](https://scipy.org/topical-software.html), there is a link to a "List of SciKits" at the right (see image below): That link points to: http://scikits.appspot.com/scikits, but I get a "Server Error" when following the link The top-level http://scikits.appspot.com page loads, but the "source" link in the footer of that page points to (https://bitbucket.org/janto/scikits_index/), which no longer seems to exist.
