MD-11 First Officer reported a HYD 2 OFF Level 2 Alert in cruise. The flight crew ran the QRH and proceeded direct to the destination airport with ATC assistance.

Narrative

At approximately XA10; we received the HYD 2 OFF Level 2 alert. We selected the Hydraulic Synoptic page and noticed that the quantity in the System 2 reservoir was decreasing rapidly. The First Officer (FO) confirmed that he had control of the aircraft and radios; and the RF2 (Relief First Officer 2) pulled out the QRH. Before we could begin running the appropriate checklist; the Hydraulic quantity decreased to zero and we received the HYD 2 FAIL level 2 alert. RF2 completed the HYD 2 FAIL QRH procedure and woke the Captain who was taking his scheduled rest. The Captain confirmed the situation and that the QRH had been executed properly. After a brief discussion amongst the crew; the decision to continue towards the destination was confirmed as we were past the ETP (Equal Time Point); and Dispatcher was contacted via SATCOM. We received concurrence from Dispatch regarding our plan to continue to ZZZ1 with the understanding that we would divert to ZZZ2 if the situation degraded. Upon completion of communications with Dispatch; Maintenance and the Duty Officer; we notified ZZZ on HF and [requested priority handling]. We were cleared direct to ZZZ1 and continued the flight without further incident. Upon arrival in the ZZZ1 terminal airspace; we fully configured the aircraft in the downwind with the RF2 monitoring the configuration and Hydraulic Synoptic pages throughout the process. The Captain conducted an uneventful; Cat I Auto Land to Runway XL and taxied the aircraft to the Company ramp without further incident.
