Transport Minister Anthony Loke Siew Fook told Dewan Rakyat that the five day long Kuala Lumpur International Airport (KLIA) system disruption in August was caused by the airport's aged Core Network Switches (CNS) system
Malay Mail reported that Loke was answering a question on the status of the police investigations into the network service disruption at KLIA.
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.
The police are still investigating the matter to determine whether there was sabotage
According to Free Malaysia Today, Loke said that the police have made an arrest over the disruption last August and no one has been implicated in the case.
Previously, investigators were looking into the possibility of a cyber attack but no evidence was found to support the suspicion.
The Malaysia Airport Holdings Berhad (MAHB) is still looking into the amount of losses resulting from the incident
The incident affected multiple systems including flight information display, immigration, and baggage handling.
This resulted in flight delays and cancellations.
The Ministry of Tourism promises to take into account the security measures proposed by the committee to prevent the incident from happening again.
