I recently had a similiar experience at Ponca City where the FSS said
the ILS was operational during the pre-flight briefing. Center cleared
me for the ILS-17 approach. I queried about the lack of GS information,
they said all was well as far as they knew. About 3 miles past the
OM,Center asked me if I wanted to switch to the LOC approach. I
didn't, so Missed approach, no GS, minimum conditions, slight icing
conditions.
Anyway, after landing and reviewing what I had done wrong, I found that
the FSS will not read you all the notams unless you specifically ask.
DUATS will not provide all the notams.

During the review of the flight, I read the notam that was similar to
the one below, I read all the FAA abbreviations list, and I can not
find what, exactly, "S-ILS" means. Just like the notam below, I don't
see where the ILS is OTS? What does "S-ILS" mean?
