Microsoft Confirms Azure Latency After Red Sea Cable Cuts

Microsoft Azure Impacted by Red Sea Cable Cuts

Microsoft confirmed that its Azure cloud services briefly experienced disruptions on Saturday after several undersea fiber cables were cut in the Red Sea.

According to Bloomberg, the incident led to increased latency for customers with traffic routed through the Middle East or terminating in Asia and Europe.

Microsoft’s Response

In a public status update, Microsoft reassured users that:

• Teams were actively monitoring and rebalancing traffic.
• Alternative routing paths were deployed to minimize disruptions.
• Repairs to undersea cables can take significant time, and the company pledged continuous optimization.

By Saturday evening, Microsoft reported it was no longer detecting Azure issues, suggesting traffic had been stabilized.

Why Undersea Cables Matter

Undersea cables carry over 95% of global internet traffic. Any disruption—whether caused by accidental damage, natural disasters, or sabotage—can have ripple effects on cloud services, financial systems, and global communications.

The Red Sea, a critical internet bottleneck, connects Europe, Asia, and Africa, making cable cuts there particularly impactful.

What’s Next for Azure Customers

While the issue was quickly mitigated, enterprises relying on Azure should:

• Monitor regional latency reports.
• Prepare for possible service rerouting in the coming weeks.
• Stay updated via Microsoft’s official Azure status page.

Key Takeaway

The Red Sea cable cuts highlight the fragility of global internet infrastructure and the dependence of businesses worldwide on a handful of submarine cables. For Microsoft, the quick stabilization underscored both the challenges and resilience of modern cloud infrastructure.
