KL ATC graveyard shift staffing "arrangements"
From page 94 of the Factual Report - 16 controllers were on the floor until midnight, after which half were sent off for a 3 hour sleep (or smoke or feed or whatever). Significantly for the region of interest (sectors 3 & 5), 2 controllers suddenly were tasked with controlling an area that 6 staff covered up until midnight. And the controller who took the last radio exchange with MH370 was off on break when more and more questions were asked higher up and from other centers. It surprises me that the numerous other AC in those sectors that night made it safely home. Reading between the lines the stress level eventually became palpable.
