The sudden Red Sea cable cuts disrupt internet across broad regions, affecting service speeds and connectivity across Asia and the Middle East. Microsoft and NetBlocks both confirmed degraded performance, while telecoms reported spiking latency that frustrated millions of users. At the same time, concerns mounted about the cause, whether sabotage or technical failure, and how long the critical infrastructure would remain vulnerable. Repairing these underwater lifelines could take weeks, and the disruptions highlight how exposed global internet systems remain to unexpected shocks.
What Caused the Disruption?
On Sunday, experts confirmed that undersea fiber cable cuts in the Red Sea disrupted internet services across multiple regions. Cable systems like SMW4 and IMEWE near Jeddah were affected, and while causes remain unclear, attention turned to ongoing Red Sea regional conflicts that have previously seen infrastructure targeted. Although Houthi rebels denied responsibility, the timing raised red flags amid escalating tensions.
Impact on Internet Services
Microsoft alerted users that Azure cloud services were experiencing increased latency, while traffic not routed through the Middle East remained unaffected. Meanwhile, users in the UAE, especially those using Etisalat and du, reported slowed access for websites and streaming. NetBlocks confirmed degraded connectivity in countries including India and Pakistan, while several Asian and Gulf regions experienced cascading slowdowns across everyday digital services.
Why This Matters Globally
The Red Sea cable cuts disrupt internet remind us how vital undersea networks are to global communication. Nearly 99% of intercontinental data traffic travels through these cables. When they fail, rerouting becomes complex, and repairs require specialized ships and favorable weather. The result is weeks of degraded service for millions of users, including businesses, governments, and individuals depending on reliable internet access.
Conclusion
This incident highlights the urgent need for stronger security and redundancy in global internet infrastructure. Stakeholders must boost protective measures and diversify connection routes to withstand such shocks. As repairs move forward, the outage may serve as a wake-up call to treat undersea cables not just as technical assets, but as fragile threads that, when cut, impact economies, societies, and global stability.
