What happened to my trusted Turtle validator and converter?

Hi!

I really liked the RDF validator and converter at 
http://www.rdfabout.com/demo/validator/?. I used it often to validate 
the Turtle I wrote and sometimes I used it to convert Turtle to RDF/XML. 
So I was on the verge of being shocked when I noticed that it was gone 
from the web. Yesterday I got a HTTP error and today I am redirected to 
a blog about RDF.

What has happened to the validator?
Will it be back?
Is there an alternative somewhere?

Regards,
Frans
