Undersea Cables Cut in the Red Sea, Disrupting Internet Access in Asia, Mideast — Key Takeaways

Overview of the Incident

In February 2024, multiple undersea communication cables in the Red Sea were severed, causing significant internet disruptions across Asia, the Middle East, and East Africa. Key affected cables included SEACOM, EIG (Europe India Gateway), and AAE-1 (Asia-Africa-Europe-1), which collectively handle approximately 25% of data traffic between Asia and Europe. Countries such as India, Pakistan, Oman, Kuwait, and Yemen experienced reduced connectivity, with some reports indicating up to 80% outages in specific regions.

Causes of the Cable Damage

While the exact cause remains under investigation, initial reports suggest the damage may stem from Houthi militant activities in the Red Sea. The group has previously targeted shipping lanes, raising concerns about deliberate sabotage. However, natural causes, such as undersea seismic activity or accidental anchor drags, have not been ruled out. Repair efforts are complicated by geopolitical tensions and restricted access to the region.

Immediate Impacts

• Economic Disruption: Financial institutions, cloud services, and stock markets in affected regions faced delays and outages, impacting trade and digital transactions.
• Latency Issues: Traffic rerouted through alternative pathways, such as cables in the Mediterranean or Pacific, increased latency by 30-50% for users in Asia and the Middle East.
• Communication Breakdowns: Telecommunication providers like Airtel and Vodafone Idea reported service degradation, affecting businesses and emergency services.

Mitigation Efforts

Internet providers, including HGC Global Communications and Cloudflare, redirected data through surviving cables like SMW-5 and IMEWE. Repair ships were dispatched, but operations face delays due to security risks in conflict zones. Experts estimate full restoration could take weeks, contingent on regional stability.

Long-Term Implications

• Infrastructure Vulnerability: The incident highlights the fragility of undersea cables, which carry 99% of global intercontinental data.
• Geopolitical Risks: Conflicts in strategic chokepoints like the Red Sea threaten critical infrastructure, urging nations to diversify routes.
• Investment in Redundancy: Governments and telecom firms may accelerate plans for redundant cables, satellite backups, and regional data hubs.

Key Takeaways

• Undersea cables remain indispensable yet vulnerable to both human and natural disruptions.
• Regional conflicts can have cascading effects on global connectivity and economies.
• Enhanced international cooperation and investment in diversified infrastructure are critical to mitigate future risks.
