rpsl bug?

I am not an rpsl guru so if this is normal, please let me now:

whois -h rpsl.ripe.net ynet.co.il

% This is the RIPE Whois server.

% See http://www.ripe.net/ripencc/pub-services/db/copyright.html

% The object shown below is NOT in the RIPE database.
% It has been obtained by querying a remote server:
% (x17.ripe.net) at port 43434.
% To see the object stored in the RIPE database
% use the -R flag in your query
%
%REFERRAL START
%ERROR:304: referral host not responding

But this does work:

whois -h whois.ripe.net ynet.co.il
