It's called planning and emergency procedures. If you have escalation levels in place ( Incase of cable failure of such importance would mean the highest escalation level) then crises management will automatically take over. If these are missing or not been adapted to given crises situations, then the outcome will always be the same. I think this is not the first time that the SAT3 cable has been a problem so there is nothing new to the operators along that route. Question takes us back in crises management and escalation levels.
