Red Sea Cable Cuts Disrupt Azure and Global Internet Connectivity
MicrosoftS Azure cloud services are currently experiencing disruptions due to damage to undersea cables in the Red Sea. This impacts internet traffic flow through the Middle East,causing delays for Azure users globally.let’s break down what’s happening, the potential causes, and what it means for you.
What’s the Situation?
Microsoft confirmed the issue on saturday, noting increased latency for Azure traffic routed through the region. importantly,traffic not passing through the Middle East remains unaffected. The company has already begun rerouting traffic via choice pathways to mitigate the impact.
However, this isn’t an isolated incident. Reports indicate similar cable cuts are affecting connectivity in the United Arab Emirates, as well as parts of Asia, including India and Pakistan.
Why are Undersea Cables Important?
These cables,laid on the ocean floor,form the essential backbone of the modern internet. They transmit the vast majority of data connecting continents. Think of them as the highways of the digital world. Disruptions to these cables, therefore, have important global consequences.
NetBlocks, an internet monitoring organization, has been tracking the outages and confirms a series of cuts in the Red Sea region. The Pakistan Telecommunication Company pinpointed the damage near Jeddah, Saudi Arabia, warning of potential peak-hour disruptions.
Potential Causes: From Accidents to Sabotage
Several factors can damage these critical undersea cables:
Ship Anchors: Accidental damage from ships dropping anchors remains a common cause.
Natural Disasters: Earthquakes and other geological events can also inflict damage.
Deliberate attacks: Regrettably, intentional sabotage is a growing concern.
A Pattern of Disruptions
This isn’t the first time we’ve seen issues in the Red Sea. In February 2024, similar cable cuts impacted data traffic between Asia and Europe. At that time, concerns were raised about potential Houthi involvement, though the group denied responsibility. Yemen’s government had previously warned of possible cable sabotage.
Furthermore, the Baltic Sea has experienced a series of incidents since Russia’s invasion of Ukraine in 2022, with damage to both undersea cables and gas pipelines. Swedish authorities even seized a ship earlier this year suspected of damaging a cable running to Latvia, with initial investigations pointing to sabotage.
What Dose This mean for You?
While Microsoft is working to reroute traffic, you may experience:
Slower internet speeds: Notably when accessing services hosted on Azure or those routed through the Middle East.
Increased latency: Delays in data transmission, impacting real-time applications like online gaming or video conferencing.
Intermittent connectivity: brief disruptions to your internet connection.
Staying Informed

The ongoing vulnerability of undersea infrastructure highlights the need for increased protection and redundancy in global internet connectivity. As we become increasingly reliant on these cables, safeguarding them against both accidental damage and malicious attacks is paramount.
