I am hoping that it will be back soon. Something at the back of my mind thinks that it was linked to one of the Universitys over there, and the server may be down for the summer ??
However I found 2 sites that I used to access via the Dutch site .
They are :-
http://ippc.nais.luftfartsverket.no/...rodrome1.html?
I find this really useful for the combined Metar/TAF/notam
and -
http://ows.public.sembach.af.mil/
whose synoptic charts tend to be a little more accurate than the Met offices.
Hope that helps
