Narrative:

Immediately after takeoff from ZZZ we received this icas message 'C hydraulic press'. Initially we thought that the APU may not have been providing enough air for the adp to work properly since we were operating with a deferred maintenance item on the right-side bleed system which required the right side to be off. We waited until flaps were retracted to see if message and light would go off. It did not and in addition to the icas and adp pressure lights we got the system light and both the left and right main pump low pressure lights on.we proceeded to execute the QRH procedure and stopped the climb at 15;000 ft. To work the checklist. After completing the checklist; we were faced with operating the aircraft without a center hydraulic system which will call for a flaps 20 landing using the alternate method of extension for the flaps and gear.after receiving weather for ZZZ1; we elected to divert to ZZZ1 because it offered an instrument approach; a longer runway and less mountainous terrain than ZZZ. We were going to land overweight; may need assistance getting off the runway and elected to [request priority handling] and have equipment standing by.

Title: B767 Captain reported a hydraulic system failure that resulted in a diversion.

Narrative: Immediately after takeoff from ZZZ we received this ICAS message 'C HYD PRESS'. Initially we thought that the APU may not have been providing enough air for the ADP to work properly since we were operating with a deferred maintenance item on the right-side bleed system which required the right side to be off. We waited until flaps were retracted to see if message and light would go off. It did not and in addition to the ICAS and ADP Pressure lights we got the System light and both the Left and Right main pump low pressure lights on.We proceeded to execute the QRH procedure and stopped the climb at 15;000 ft. to work the checklist. After completing the checklist; we were faced with operating the aircraft without a center hydraulic system which will call for a flaps 20 landing using the alternate method of extension for the flaps and gear.After receiving weather for ZZZ1; we elected to divert to ZZZ1 because it offered an instrument approach; a longer runway and less mountainous terrain than ZZZ.
