Issue with SSDI Search

There seems to be a problem searching the Social Security Death Index online.  I searched for William Force who was born 1903 in New York State.  In 1930 he lived in Brooklyn, Kings County, New York.  I tried searching for a death record using Ancestry, Familysearch, Genealogybank.com, NEGHS American Ancestors.org and World Vital Records.  Only Genealogybank found a record!  Alas, this is also a subscription site and try to capture you this way.  At least they let me register and view the record.
