NT cites 7 cable systems in November 9 backup report
National Telecom would prioritise bandwidth for security, government, medical and financial services in Thailand if a major disruption occurred.
- National Telecom (NT) will use its seven submarine cable systems to reroute internet traffic and maintain connections if an international link is severed.
- During a major disruption, the backup plan prioritizes bandwidth for essential services, including security agencies, government bodies, medical services, and the financial system.
- The contingency plans also outline responses to other major threats, such as complete power-system outages, to ensure business continuity.
- NT also enhances stability by securing extra network capacity on various international routes and using local content caching to reduce reliance on overseas servers.
National Telecom Public Company Limited (NT) has outlined backup arrangements involving seven submarine cable systems to maintain Thailand’s internet connections if an international cable link is severed. The plans also cover major power failures and priority communications for essential services, Thansettakij reported on November 9, 2026.
Colonel Sanpachai Huvanandana, president of NT, said the company had comprehensively prepared its international internet network and backup systems to maintain stable services 24 hours a day.
Sanpachai said NT had submitted its risk-response and cybersecurity monitoring plans to the Ministry of Digital Economy and Society, as instructed.
NT would reroute traffic after a cable cut
Sanpachai said traffic could be redirected to alternative routes through NT’s seven submarine cable systems, which connect to all regions of the world, if an international link were cut.
NT had also secured network capacity in advance on a range of international routes through global service providers, Sanpachai added.
Sanpachai said NT’s international submarine cable systems were designed with high levels of security to protect against external intrusion. NT also uses caching and locally hosted content to reduce the need to connect to overseas servers, he added.
Essential services would receive priority bandwidth
Under NT’s business continuity plan, security agencies, government bodies, medical services and the financial system would receive priority bandwidth if a major disruption occurred, Sanpachai said.
Sanpachai said NT had assessed threats to the resources needed to operate its systems, including a complete power-system outage, to prepare its business continuity response.
NT would manage communications according to priority and use broadcasting systems to communicate with the public while services were being restored to full operation, Sanpachai said.
NT monitors cyber threats to public and private clients
“NT currently provides cybersecurity services to both government and private-sector organisations, with continuous monitoring and assessment of cyber threats,” Sanpachai said.
Sanpachai said NT was ready to use technology and cyber defence systems meeting international standards to protect organisations’ information systems, strengthen the security of digital infrastructure and improve its ability to prepare for and respond effectively to cyber threats.
