At the page dewiki:Staatscourant I tried to run RENDER/Supporting Tools for Wikipedia/Article Monitor and got an error on the gadget. It seems like the service is active. The problem could be as simple as use of deprecated functions, and an image that has been moved.
There is also a note at Talk:RENDER#Cleanup, but this is more a notice of the documentation which seems to be outdated and possibly wrong.
