Cool! I noticed the following: from many NLNOG RING nodes I can reach
that IP address, but not from 195.66.134.42:

    deepmedia01.ring.nlnog.net:~$ mtr -z -w -r 134.195.47.1

Do you have a BGP route for 195.66.134.0/23 on the router with
134.195.47.1 ?

Do you have a traceroute towards 195.66.134.42?

Kind regards,
