Simultaneous faults near Jeddah slow connectivity as operators reroute traffic; motive and cause remain unconfirmed.
Lead
Multiple undersea telecommunications cables in the Red Sea suffered damage over the weekend, throttling internet performance across parts of Asia and the Middle East and underscoring how exposed global data arteries remain in a tense region. Network monitors and service providers reported widespread slowdowns, while investigations into the precise cause are ongoing.
Major systems affected
– Two key routes—the South East Asia–Middle East–Western Europe 4 (SMW4) and the India–Middle East–Western Europe (IMEWE) systems—experienced failures in waters off Jeddah, Saudi Arabia, leading to degraded service in several countries. Operators shifted traffic onto alternate paths to stabilize connectivity, but users continued to face higher latency and reduced speeds during peak periods.
– Cloud platforms reported regional impact. Microsoft cautioned that services traversing Middle East paths could see elevated latency following the fiber cuts, though traffic outside the corridor remained stable. The company rerouted Azure workloads to minimize disruption.
Regional impact snapshot
– Pakistan: National carriers acknowledged cable damage and warned of performance dips, particularly in busy hours, as restoration and rerouting efforts proceeded.
– United Arab Emirates: Customers on major networks, including Etisalat and du, reported slower broadband and mobile data, even as authorities offered limited public detail on root causes.
– India: Monitoring groups flagged performance degradation, though Indian operators emphasized resilience through redundant cables and alternative transit routes.
– Kuwait: Some networks reported successful rerouting with minimal domestic impact, highlighting the benefits of multi-path diversity.
Attribution still uncertain
– The incident occurred along a maritime corridor that has seen persistent security risks, including attacks on commercial vessels amid regional conflict dynamics. Authorities have not verified a cause, and no group has credibly claimed responsibility.
– Yemen’s Houthi movement has been accused in the past of threatening subsea infrastructure, allegations it has denied. While their media channels noted the connectivity issues, they did not assert involvement in this event.
Why the Red Sea matters
– The Red Sea–Egypt–Mediterranean chokepoint carries a substantial portion of intercontinental internet traffic between Asia, the Middle East, and Europe. Concentration of cables along this route means single points of failure can have outsized effects, even when providers maintain backups.
Repair outlook
– Fixing subsea cables typically requires specialized vessels to locate, retrieve, splice, and re-lay the fiber—a process that often stretches over weeks depending on weather, depth, permitting, and maritime security conditions.
– The region’s geopolitical sensitivities and heightened naval activity may complicate repair timelines and vessel access, increasing reliance on backup routes until full capacity is restored.
What to watch next
– Restoration windows from cable operators and marine maintenance consortia.
– Additional traffic engineering by carriers and cloud providers to normalize latency.
– Any official findings on the cause, including maritime incidents (e.g., dragging anchors) versus deliberate interference.
– Temporary capacity boosts on alternative corridors (e.g., via the Cape of Good Hope or terrestrial segments) to offset congestion.
