The growing threat to undersea Internet cables

The global network of undersea cables, essential for internet connectivity, faces increasing threats from various sources. A notable incident occurred in early 2022 when a volcanic eruption in Tonga severed its internet connection, highlighting the vulnerabilities of this infrastructure. Undersea cables, which span approximately 1.5 million kilometers, are crucial for transmitting data globally, yet they are often overlooked by the public, who perceive the internet as a wireless entity. Concerns have been raised about potential sabotage by state actors, particularly Russia, which has been accused of surveilling these cables. However, experts suggest that accidental damage from human activities, such as fishing and shipping, poses a more significant risk. The uneven distribution of these cables globally exacerbates the issue, with some regions, like Tonga, having limited connectivity options. Following the Tonga incident, there have been calls for improved security and infrastructure, but the focus remains on economic viability rather than resilience. As digital demand grows, the disparity in cable distribution threatens the promise of equitable internet access, particularly for vulnerable regions.

- Undersea cables are vital for global internet connectivity but are increasingly threatened.

- Accidental damage from human activities is a greater risk than sabotage by state actors.

- The distribution of undersea cables is uneven, leaving some regions with limited connectivity.

- Recent incidents have prompted calls for improved infrastructure and security measures.

- Economic factors often overshadow the need for resilient internet networks in vulnerable areas.
