Taiwan Throttles Mobile Internet Speeds in Defence Drill, Raises Questions About Preparedness
Taiwan’s annual Han Kuang war games have once again highlighted a crucial aspect of these exercises: the government’s decision to throttle mobile internet speeds in case of a potential Chinese invasion or natural disaster. The intention behind this move is admirable – simulating communication disruption and testing the public’s resilience. However, it raises questions about the effectiveness of such drills in preparing Taiwanese residents for real-world scenarios.
The limited scope and execution of these exercises fall short of the mark. By confining throttled internet speeds to specific regions, including Taipei and central Taiwan, while leaving out southern and eastern areas critical for military and industrial infrastructure, the government creates an unrealistic narrative of what a full-scale invasion would look like. This narrow focus overlooks the fact that any potential cyberattacks or communications blackouts could cripple Taiwan’s digital backbone, regardless of geographical location.
The public’s response to these drills has been telling. Many residents have grown complacent with civil defence routines, treating them as minor inconveniences rather than genuine threats to their safety. This complacency is concerning, especially when considering the very real vulnerabilities Taiwan faces in terms of cyberattacks and undersea cable sabotage. The island’s reliance on international submarine cables for global data traffic makes it susceptible to physical damage or grey zone threats from nearby vessels.
In 2023, the Matsu islands were knocked offline for several weeks after two undersea cables connecting them to the outside world were severed – an incident that Taiwanese authorities suspected was linked to Chinese vessels. The scale and frequency of these attacks underscore the need for robust preparedness measures.
Taiwan’s National Security Bureau reported a staggering 2.63 million intrusion attempts in 2025, but it remains unclear whether the public is taking these threats seriously enough. The drill by design is far from perfect – limited in scope, poorly executed, and seemingly ineffective at instilling a sense of urgency among residents.
As Taiwan navigates its complex relationship with China and the ongoing threat of cyberattacks and digital blackouts, it faces a critical juncture. The government must revisit its strategy and consider more comprehensive approaches to simulating real-world scenarios. This includes increasing public awareness about the risks associated with these threats and engaging residents in genuine emergency preparedness exercises.
The stakes are high, and Taiwan’s success will depend on its ability to adapt and improve its response to potential cyberattacks and communications blackouts. As the island continues to push for greater international cooperation and support in the face of Chinese aggression, it must demonstrate a unified commitment to defending its digital infrastructure and safeguarding its citizens’ well-being.
Taiwan’s war games test falls short because they fail to genuinely prepare residents for the devastating consequences of a full-scale invasion or natural disaster. The public needs more than just symbolic gestures; it requires robust exercises that simulate real-world scenarios and foster genuine resilience in the face of adversity.

The government's decision to throttle mobile internet speeds during the Han Kuang war games is a misguided attempt to simulate crisis conditions, but it falls short in adequately preparing Taiwanese residents for real-world cyber threats. The exercises' narrow focus on specific regions overlooks the vulnerability of Taiwan's digital backbone to widespread disruptions, including undersea cable sabotage. Furthermore, the public's growing complacency with these drills suggests that more needs to be done to educate citizens about the actual risks and consequences of a potential Chinese invasion or natural disaster.

While Taiwan's Han Kuang war games aim to test emergency preparedness, they often prioritize showmanship over realism. By selectively throttling internet speeds in specific regions, the government creates a skewed narrative that may not accurately reflect the actual impact of a cyberattack or natural disaster on critical infrastructure. What's often overlooked is the potential for cascading effects from sabotage of undersea cables connecting Taiwan to international networks. A more nuanced approach would focus on simulating systemic disruptions that could cripple the island's digital backbone, rather than just local internet speeds.

While Taiwan's Han Kuang war games are a commendable effort to simulate disaster scenarios, their reliance on throttled internet speeds as a key component raises questions about the government's real-world preparedness. What about the island's power grid? Taiwan's infrastructure is increasingly digitalized, making energy and communication systems intertwined. A blackout could cripple both the internet and critical services like hospitals and emergency services. The drills should test resilience against not just cyberattacks but also simultaneous power outages to paint a more accurate picture of what residents might face in a full-scale invasion or disaster scenario.
