He said that the massive outage was due to the airport's 21-year-old Core Network Switches (CNS) system that has not been upgraded since operations began in 1998.

"It was never changed. The core switches connect the entire network system at KLIA," he added.

The Airport's Total Management System was affected from the night of 21 August to 25 August due to the CNS glitch.
