Of all the large interferometric gravitational-wave detectors, the German/British project GEO600 is the only one which uses dual recycling. During the four weeks of the international S4 data-taking run it reached an instrumental duty cycle of 97% with a peak sensitivity of 7 x 10(-22) Hz(-1/2) at 1 kHz. This paper describes the status during S4 and improvements thereafter.
