PharmaOntology / TMO KB Wiki Demo Page.... BROKEN sparql endpoint

Hi,

I�d hoped to use some of the work we did for the TMO / TMOKB in a course I�m teaching (now [*]) however I�m finding broken links on this page:

http://www.w3.org/wiki/HCLSIG/PharmaOntology/TMKB

Virtuoso provisions a :

  *   SPARQL endpoint : http://tm.semanticscience.org/sparql
  *   Full text faceted browser: http://tm.semanticscience.org/fct

And..
We can pose SPARQL Queries<http://www.w3.org/wiki/HCLSIG/PharmaOntology/Queries> questions to the SPARQL endpoint.   /// The page with the queries is there, however�..
none can be run.

I had hoped it was a momentary glitch, but it�s now been at least a few days.
Season�s Greetings to all!

Joanne
