Brinztech Alert: Red Sea Cable Cuts Cause Widespread Internet Disruptions

Critical Infrastructure Analysis

Significant internet disruptions have been reported across the Middle East and South Asia following multiple undersea cable cuts in the Red Sea. Tech giant Microsoft confirmed the issue, warning customers that its Azure cloud services are affected and that network traffic traversing the region may experience increased latency. The disruptions, which began on September 6, have been independently verified by the internet connectivity watchdog NetBlocks, which reported degraded connectivity in several countries including Saudi Arabia, Pakistan, the United Arab Emirates, and India.  

The connectivity issues are reportedly due to failures in the SMW4 and IMEWE cable systems near Jeddah, Saudi Arabia. While undersea cables can be damaged by accidents like ship anchors, the incident occurs in a region of high geopolitical tension. In early 2024, several cables in the Red Sea were cut, though Yemen’s Houthi rebels, who are active in the area, denied responsibility. The current incident again raises serious concerns about the security of the physical infrastructure that underpins the global internet.  

Key Insights

This major infrastructure event provides several critical insights:

• Widespread Disruption to Critical Infrastructure: This incident is a stark reminder of the fragility of the internet’s backbone. The physical cuts to just two cable systems are having confirmed, real-world consequences for major cloud providers like Microsoft and for internet users across multiple nations, demonstrating how a localized event can have widespread effects.  
• The Middle East as a Critical Data Hub: The location of the cuts near Jeddah highlights the Middle East’s role as a critical chokepoint for data traffic linking Asia and Europe. Disruptions in this narrow corridor can degrade intercontinental connectivity for millions of users and businesses.  
• Ambiguous Cause in a Geopolitical Hotspot: While the cause remains unconfirmed, the context is critical. The Red Sea is a major global shipping and data lane that is also a zone of active conflict. The possibility of deliberate sabotage, in addition to accidental damage, makes this a serious geopolitical concern.  

Strategic Recommendations

In response to the vulnerabilities highlighted by this incident, businesses and governments must prioritize infrastructure and service resilience:

• Invest in Network and Cloud Resilience: For businesses, this incident is a clear signal to avoid single points of failure. Critical operations should be architected with multi-region and multi-cloud failover capabilities. Utilizing diverse network carriers and routes is essential to ensure traffic can be rerouted around major disruptions.
• Enhance Physical Security of Critical Infrastructure: For governments and telecommunications consortiums, the physical security of subsea cables and their landing stations is paramount. Increased international cooperation, surveillance, and security are needed to protect these vital assets, especially in contested maritime regions.  
• Develop and Test Business Continuity Plans: Organizations must have well-documented and tested business continuity plans that specifically account for a prolonged loss of primary internet connectivity. This includes having backup communication methods and procedures for operating in a degraded network environment.
