Yemen Mobile Fiber Optic Cable Outage

Multiple subsea fiber optic cables in the Red Sea near Yemen were severed, causing widespread internet disruptions across the Middle East, South Asia, and East Africa.Overview of the OutageThe outage began on September 6, 2025, at 05:45 UTC, when several undersea fiber optic cables in the Red Sea were cut or damaged, including the SMW4 and IMEWE cable systems near Jeddah, Saudi Arabia. These cables are critical for global internet traffic, linking Asia, the Middle East, and Europe, and carry a significant portion of intercontinental data, including cloud services, banking, and streaming traffic (Microsoft, NetBlocks, Independent) .Geographic and Service ImpactThe disruption affected multiple countries, including Yemen, India, Pakistan, the UAE, and other parts of the Middle East and South Asia. Users of services like Microsoft Azure experienced increased latency and intermittent access, while telecom operators had to reroute traffic over alternate paths, which slowed connectivity and caused congestion during peak hours (Microsoft, Converge Digest, Independent) .Possible CausesWhile the exact cause remains uncertain, reports suggest two main possibilities:Deliberate sabotage: Yemen's Houthi rebels have been active in the Red Sea, attacking ships and potentially targeting subsea cables as part of regional geopolitical tensions. Some media outlets consider them a plausible suspect due to prior attacks and published maps of cable routes (Factually, Ynet News) .Accidental damage: Undersea cables are vulnerable to ship anchors, fishing gear, or maritime accidents. Historical incidents, such as a cargo ship dragging its anchor in March 2024, have caused similar cable damage, highlighting that accidents remain a credible explanation (Factually, Ynet News) .Repair and MitigationRepairing subsea cables is logistically challenging and can take weeks, especially in politically sensitive waters like the Red Sea. Operators are currently rerouting traffic, rebalancing network loads, and seeking alternate capacity through regional providers to minimize disruption (Microsoft, Converge Digest) . Customers may continue to experience slower speeds and intermittent connectivity until repairs are completed.Key TakeawaysThe Red Sea is a strategic chokepoint for global internet traffic, making outages in this region highly impactful.Yemen Mobile and other regional ISPs are affected due to the cables passing through Yemeni maritime jurisdictions.Users should expect continued latency and potential service degradation, particularly during peak hours, until full repairs are completed.The incident underscores the vulnerability of subsea infrastructure to both geopolitical tensions and accidental damage, highlighting the need for alternative routing and geographic diversification of internet cables. This outage demonstrates the critical role of subsea fiber optics in global connectivity and the challenges in maintaining uninterrupted service in conflict-prone regions.
