Microsoft’s Azure cloud platform is experiencing disruptions due to severed undersea fiber optic cables in the Red Sea. This incident, which began on Saturday, September 6, has caused delays and increased latency for users whose internet traffic passes through the Middle East. While a complete outage was avoided due to the company’s ability to successfully reroute data, the change in network paths has resulted in a noticeable impact on service performance for affected customers.
The company’s status update confirmed that network traffic traversing the Middle East might experience higher latency. To mitigate this issue, Microsoft immediately redirected traffic through alternate network paths, a crucial step that prevented a full-scale interruption of services. However, this rerouting, while effective, sends data on a longer, less direct path to its destination. Microsoft has clarified that network traffic not routed through the Middle East remains completely unaffected by the incident.
For businesses and individuals who rely on Azure, this increase in latency translates directly to slower response times for applications, websites, and data access. Although this is not a full-scale outage, the delays can significantly impact performance-sensitive operations, such as financial transactions, real-time data processing, and other cloud-hosted services that require near-instantaneous communication. The severity of the impact depends on the user’s location and the specific services they are using, with those in or connected to the Middle East being the most affected.
The incident highlights the critical role of the Red Sea as a major corridor for global internet connectivity. This narrow waterway is a vital link between Europe, Asia, and Africa, with a large portion of the world’s internet data passing through the subsea cables laid on its seabed. Damage to these cables in such a heavily trafficked and confined area can have a disproportionately large impact on international connectivity, affecting not just one provider but potentially multiple telecommunication companies.
This event follows other reports from the weekend indicating that the same cable cuts had already begun affecting internet services in the United Arab Emirates and parts of Asia, suggesting a widespread problem affecting a range of telecommunication providers. The lack of detail from Microsoft regarding the cause of the damage leaves open questions about the nature of the incident. However, the company’s swift response in rerouting traffic has demonstrated its ability to maintain service continuity, even under difficult circumstances, by leveraging its extensive and redundant network infrastructure.
