This page loads successfully: http://savannah.nongnu.org/projects/lmi but clicking its "Homepage" link, i.e.: http://www.nongnu.org/lmi/ now gives "500 Internal Server Error". This always worked in the past. I've tried refreshing the page manually and using a different browser.
The same error results from attempting to access project webpages, e.g.: http://www.nongnu.org/lmi/7702.html although that page's source is definitely in the "web" cvs: http://web.cvs.savannah.gnu.org/viewvc/lmi/lmi/7702.html?view=log
