Over the recent weekend, the digital world faced a stark reminder of its vulnerabilities when Seacom, a crucial link in Africa’s connection to the global internet, experienced significant subsea cable disruption in its network in the Red Sea. This incident, confirmed by multiple sources including TechCentral and official statements from Seacom, has highlighted the fragility of the underwater cables that underpin our global communication systems. As one of Africa’s premier undersea communications and fiber network operators, Seacom plays a pivotal role in connecting the continent to the rest of the world, making this disruption more than a mere inconvenience.
On the 24th of February, Seacom, a key player in subsea cable operations, reported a significant outage impacting the section of its network stretching from Mombasa, Kenya, to Zafarana, Egypt. This incident, which took place in the vicinity of the Red Sea, not only affected Seacom’s infrastructure but also had repercussions for adjacent cable systems in the region.
As of now, Seacom has not been able to pinpoint the exact cause of this disruption. The company is actively collaborating with its cable repair partners to evaluate the possibilities for repair, a task made more complex by the geopolitical tensions and sensitivities associated with the Red Sea area.
In response to this challenge, Seacom has tried to maintain traffic flow within Kenya, Tanzania, Mozambique, and South Africa by leveraging its existing cable network for both transmission and IP services. To mitigate the impact on services destined for Europe and beyond, the company implemented rerouting protocols through alternative submarine cable routes such as Equiano, PEACE, and WACS. This rerouting, supported by Seacom’s terrestrial infrastructure, led to routing disruption, with some noticeable increase in latency for a lot of companies throughout the region.
Despite the adverse effects of the outage on businesses across East and Southern Africa, Seacom has been proactively working to sustain service continuity. The company had previously issued a cautionary note to customers on the 5th of February, warning of potential delays in repair operations due to the unstable security conditions in the region. Seacom is now focused on establishing restoration timelines and plans to keep its clients informed of developments as they unfold.
While SEACOM has assured its customers of unaffected capacities, the broader issue encompasses more than just available bandwidth. CDNs and content behemoths like Netflix, Microsoft, Amazon, and Facebook, might face challenges due to possibly strained capacity.
Navigating this complex landscape calls for a strategic reliance on peering exchanges, an indispensable mechanism that facilitates cost-effective data interchange within diverse data center environments. In the current predicament, it’s not merely about possessing extra international capacity; the real challenge is rerouting this traffic to prevent congestion at local peering junctures, especially during peak times.

The Red Sea region, a critical juncture for global telecommunications, is serviced by several undersea cables that are pivotal for internet connectivity between continents. These cables are operated by a consortium of international telecommunications companies and regional players. While the exact number of cables can vary due to new deployments and decommissions, some of the notable cables in this region include:
Operators of these cables include global telecommunications giants as well as regional telecom companies, all of whom share the responsibility for the maintenance and operation of these critical infrastructures. Here are some of the major operators:
The occured incident illuminates the broader implications for companies reliant on these critical undersea infrastructures. The potential for disruptions, whether from natural phenomena or geopolitical strife, poses substantial risks to uninterrupted global communications, impacting businesses, economies, and even the day-to-day lives of individuals dependent on seamless connectivity.
In response to such vulnerabilities, companies can adopt several strategies to safeguard their operations against similar disruptions:
Diverse Routing: Implementing alternative routes and leveraging multiple cables can provide redundancy, ensuring that a single point of failure does not cripple the network. Seacom’s rerouting of IP services through alternative cables like Equiano, PEACE, and WACS exemplifies this approach.
Enhanced Monitoring and Quick Response Systems: Advanced monitoring technologies can detect faults more swiftly, enabling quicker response times and reducing downtime. Employing AI and machine learning algorithms can predict potential failure points, facilitating preemptive actions.
Strategic Partnerships and Collaborations: Forming alliances with other network operators and consortia can enhance resource sharing and collective response strategies, improving the overall resilience of the global communications infrastructure.
Infrastructure Investments: Investing in the physical security and durability of cables, especially in conflict-prone or environmentally sensitive zones, can prevent intentional and accidental damages.
Regulatory and Policy Advocacy: Engaging with international bodies and governments to secure undersea cables as critical global infrastructure can lead to stricter regulations, recommendations (e.g., the EU Recommendation on the Security and Resilience of Submarine Cable Infrastructures) and protections against intentional sabotage.
In this complex landscape, technologies like the Noction Intelligent Routing Platform emerge as a critical tool for maintaining and enhancing connectivity. IRP dynamically optimizes internet traffic paths, ensuring data transmission takes the most efficient and reliable route. For businesses affected by undersea cable disruptions like Seacom’s, Noction’s intelligent routing offers several key advantages:
