Narrative:
Rudder fail cas message followed by dutch roll induced by light turbulence. Unable to maintain altitude or airway. Initially [requested special handling] as dutch roll increased in intensity. Requested block altitude initially; but ATC did not understand this request. Requested lower altitude and descended to FL301. Was able to stabilize the dutch roll and reconnect autopilot. Followed QRH procedure; but rudder remained completely failed including trim function; discussed options for landing airport and diverted to ZZZZ due to favorable wind conditions and weather. Completed safe landing at ZZZZ about 1:40 after initial event. Flight control computers were operational hydraulics were all operational remote electronic units 15 and 16 were both failed along with rudder lvdt disconnect.
