After takeoff the 'RUD STBY UPR OFF' and 'RUD STBY LWR OFF' level one alerts illuminated. After running the checklist (AOM) we called Dispatch/Maintenance/MD-11 for consultation. I elected to change destinations so as to facilitate repairs before the oceanic crossing. Dispatch gave us a diversion release; we coordinated a new destination with Center and we also coordinated approximately 18 minutes of fuel dump with Center. Dumping was accomplished on the airway; at cruise altitude of FL290 Mach .820 in accordance with the QRH checklist. Dump was secured at 500;000 LBS gross weight. This allowed the aircraft to re-distribute fuel before the approach phase began. We made an uneventful landing where the Hydraulic System Controller (HSC) was replaced. The flight resumed without further problems.
A MD-11's EICAS alerted RUD STBY UPR OFF and RUD STBY LWR OFF so fuel was dumped and the flight diverted to an enroute airport for repairs.
