B757 first officer experiences a jolt at FL340 accompanied by autopilot disengaging; flight directors disappearing and an EICAS message for the right rec fan. A strong burning smell is reported by the lead flight attendant and the crew dons oxygen masks and diverts to the nearest suitable airport. The smell dissipates during descent and an overweight landing ensues with normal taxi to parking.

Narrative:
Cruising at FL340; we felt a jolt and at the same time the autopilot disengaged; flight directors disappeared and an EICAS message appeared (right rec fan). Since I was the pilot flying; I busied myself engaging the autopilot; the captain got a call from the back. A first class flight attendant indicated a strong burning smell; and a loss of galley and entertainment power. After the captain hang up; we smelled it on the flight deck. We donned our mask and made a plan of action to divert. We decided to divert to ZZZZ initially but changed as soon as we made the turn because ZZZZ1 was a lot closer. The captain worked the radios; FMS and ACARS (company notification). The relief pilot; after coming back from his short break; worked the QRH and made the necessary PA announcements. I flew the airplane; trying to keep the descent going and not fly to far away from ZZZZ1. The burning smells dissipated during descent and approach. After an uneventful overweight landing; the captain decided to taxi to the gate/hard stand.
