wonder if the failure is on a line or neutral? or even worse, a PME neutral?
one way to find out would be hammer in a rod, and wire a light between line & rod... obviously this needs to be done with caution.... if it flickers at same time as others, its a line problem. if it doesnt flicker, its a neutral problem
