Microsoft Azure Faces Disruptions Amid Red Sea Cable Damage

A significant disruption in global internet connectivity has impacted Microsoft Azure services following multiple undersea cable cuts in the Red Sea. The incident, which began on September 6, 2025, affected several key subsea cables, including SMW4, IMEWE, and FALCON, leading to increased latency and slower data transmission for users in Asia, the Middle East, and parts of Europe.

Impact on Microsoft Azure Services

Microsoft acknowledged the issue, stating that users of its Azure cloud platform might experience higher latency due to the damage to undersea cables. The company reported that traffic routed through the Middle East, particularly between Asia and Europe, was most affected. In response, Microsoft rerouted traffic through alternative paths to mitigate service disruptions. While the company assured users that services remained operational, the rerouting led to temporary delays for some users.

Wider Internet Disruptions

The cable cuts have had a broader impact on internet connectivity across the region. Countries including India, Pakistan, Saudi Arabia, Kuwait, and the United Arab Emirates reported slower internet speeds and connectivity issues. Telecom providers such as Etisalat and Du in the UAE confirmed the disruptions, which have also affected other cloud services and online platforms.

Challenges in Repairing Subsea Cables

Repairing damaged undersea cables is a complex and time-consuming process. The Red Sea region, a critical hub for global internet traffic, presents logistical challenges for repair efforts. Factors such as maritime traffic, political considerations, and the need for specialized equipment can delay restoration. Experts suggest that full repairs could take weeks, depending on the severity of the damage and the availability of resources.

Conclusion

The damage to undersea cables in the Red Sea underscores the vulnerability of global internet infrastructure. While Microsoft Azure has implemented measures to mitigate the impact, the incident highlights the importance of robust and resilient communication networks. As repair efforts continue, users in affected regions may experience intermittent service disruptions. The event serves as a reminder of the critical need for secure and redundant pathways in global data transmission systems.
