A major disruption in global internet connectivity has been reported after critical submarine cables in the Red Sea were damaged. These undersea cables play a vital role in carrying internet traffic between continents, and their damage has caused widespread slowdown and latency issues for users across multiple countries, including India.
Internet Disruption After Red Sea Cable Damage
Reports confirm that several optic fiber cables running under the Red Sea have suffered severe damage, directly impacting internet performance worldwide. Users have been facing slow browsing speeds, delays in accessing services, and interrupted online communication. The problem has extended to enterprise services as well, with Microsoft Azure being significantly affected.
The damaged cables include some of the most important international systems such as SEACOM/TGN-EA, AAE-1, and EIG. These cables together carry about 17 percent of global internet traffic between Europe and Asia. Their disruption has caused delays in data transfer between continents, raising concerns about the vulnerability of undersea infrastructure.
Microsoft Azure Faces Major Impact
Microsoft has acknowledged that the cable disruption has had a serious effect on its Azure platform. Users, particularly those depending on data traffic between Asia and Europe, are experiencing noticeable slowdowns. The company is currently routing traffic through alternative pathways to minimize the disruption, but officials warn that repairs may take considerable time.
Azure engineers are working to ensure continuity by balancing data loads and optimizing traffic through backup systems. However, given the scale of the disruption, users can expect continued issues until the damaged cables are fully restored.
Unclear Cause Behind Cable Breaks
The exact reason for the cable damage has not been confirmed yet. Historically, commercial vessels have been linked to similar incidents, as ship anchors can sometimes damage undersea cables. However, in this case, experts are also considering the possibility of deliberate sabotage.
There is speculation that digital infrastructure in the Red Sea region may have been intentionally targeted to disrupt global connectivity. Analysts warn that hostile groups may exploit vulnerabilities in critical undersea networks to gain geopolitical leverage.
Some reports have pointed towards the possibility of Yemen’s Houthi rebels being involved. Analysts believe they could be attempting to pressure Israel into ending the Gaza conflict by targeting international communications.
Widespread Internet Connectivity Issues
Internet watchdog NetBlocks confirmed that disruptions in the Red Sea cables have affected multiple countries, including India and Pakistan. The group traced part of the issue to failures near Jeddah in Saudi Arabia, where SMW4 and IMEWE cable systems were impacted.
These failures have slowed connections, disrupted cloud services, and caused packet losses across several networks. Businesses dependent on high-speed connectivity for financial transactions, cloud computing, and communication services are among those hit hardest.
Operations of Affected Cable Systems
The South East Asia–Middle East–Western Europe 4 (SMW4) cable is operated by Tata Communications, a part of the Indian business conglomerate. The India-Middle East-Western Europe (IMEWE) cable is maintained by a separate consortium under the supervision of Alcatel-Lucent.
Despite the widespread impact, neither Tata Communications nor the IMEWE consortium has released an official statement about the disruption. Technical experts say that restoring undersea cables can take weeks or even months, depending on the damage location and prevailing security conditions in the Red Sea.
Houthi Rebels Under Suspicion
Earlier this year, the internationally recognized Yemeni government in exile accused Houthi rebels of planning attacks on submarine cables in the Red Sea. Several cables were cut, though the Houthis publicly denied responsibility at the time.
On Sunday, Houthi-linked Al-Masirah satellite news channel cited NetBlocks in acknowledging disruptions caused by cable damage. This has fueled suspicions that the group may be linked to the latest incident.
Previous Houthi Attacks on Maritime Infrastructure
Since November 2023, Houthi militants have carried out over 100 attacks on ships in the Red Sea and surrounding waters. Using missiles and drones, they targeted vessels in connection with the Israel-Hamas war in Gaza. At least four ships were sunk during that period, and eight sailors lost their lives.
Although the Houthis briefly paused attacks during a temporary ceasefire in the conflict, renewed hostilities in recent months have triggered fresh assaults. The pattern of targeting maritime infrastructure has raised alarm that undersea digital infrastructure is now also at risk.
Strategic Importance of Red Sea Cables
The Red Sea is one of the most important corridors for global internet traffic. Submarine cables laid here connect Asia, Africa, and Europe, ensuring smooth data exchange across regions. A significant share of international bandwidth depends on these routes.
Damage to these cables not only affects individual users but also disrupts multinational corporations, government agencies, financial markets, and cloud-based services. With remote work, digital trade, and online communication now central to modern economies, disruptions in submarine networks can trigger widespread economic consequences.
Repair Challenges and Global Implications
Repairing undersea cables in conflict zones like the Red Sea presents immense challenges. Specialized ships and equipment are required to locate, lift, and fix the damaged cables. In regions where security threats exist, these operations become riskier and more time-consuming.
The longer the repairs take, the greater the economic and social consequences. Cloud computing, streaming services, financial transactions, and even military communications can face interruptions. With more than 95 percent of global internet traffic carried by undersea cables, the importance of their protection has become a global security priority.
The Red Sea cable damage is a stark reminder of how vulnerable global connectivity is to physical and geopolitical risks. As investigations continue into the cause, suspicion of sabotage highlights the urgent need for stronger international agreements to safeguard undersea networks.
For users in India and across Asia, the slowdown underscores the reliance on fragile submarine infrastructure. Companies like Microsoft are working tirelessly to maintain services, but long-term solutions require global cooperation.
The incident may also prompt governments and corporations to invest in diversifying routes, strengthening redundancy systems, and enhancing maritime security. With the world increasingly dependent on fast, reliable internet, protecting submarine cables has never been more critical.
