Vodacom Business has successfully deployed a Mobile Private Network (MPN) at Sasol’s synthetic fuel facility in Secunda, Mpumalanga 

This partnership represents a significant step forward in using next-generation connectivity to drive greater operational efficiency and digital transformation in heavy industry.

Victor Bester, Sasol’s executive vice-president of operations and projects, explained, “As part of Sasol's digitalisation journey, there is a focus on utilising technology to improve processes that impact safety and efficiency across our facilities. This initiative allows us to accelerate these efforts through improved connectivity and control of the mobile network deployed at our Secunda production facility. Our collaboration with Vodacom Business creates opportunities for us to do things differently and grow our digital maturity. We look forward to the positive impact this advanced connectivity solution will have on our operations.”

Vodacom’s MPN is designed to offer tailored, secure, and high-performance mobile network access – critical for large-scale, high-stakes environments like Sasol’s. Peter Malebye, managing executive at Vodacom Business, said, “Our MPN solution provides a dedicated, secure, and high-performance mobile network tailored to meet the specific needs of Sasol's operations. It delivers the scalability and reliability required to ensure continuity for its mission-and business-critical applications.”

According to Malebye, this level of connectivity enables far more than just smoother communication. “When all of this comes together, an organisation can ultimately bring in other innovations, such as digital twins or enable remote and autonomous operations to improve planning,” he added.

Instead of using Wi-Fi to connect around 3,000 staff across Sasol’s vast facility—which would require an enormous and costly infrastructure rollout—the MPN creates a smarter, more streamlined solution. By integrating Vodacom’s network with Sasol’s internal systems, the site now benefits from better-connected employees, equipment, and assets.

This shift not only enhances real-time monitoring but also boosts safety and compliance, enables more effective asset management, improves team collaboration, and sharpens overall operational performance. Crucially, MPNs deliver consistent coverage in areas where public mobile networks may be patchy or completely unavailable.

Unlike public mobile networks, an MPN provides exclusive access, meaning the network can be fine-tuned for specific operational needs. These networks offer increased control, robust security, and ultra-low latency.

What’s more, data processed via the MPN stays entirely on-site—an essential feature for mission-critical operations like Sasol’s, where high uptime and minimal latency are non-negotiable.

“While MPNs are becoming increasingly relevant in a South African context, they are not yet as widespread as traditional public mobile networks,” Malebye noted. “Vodacom Business has been a pioneer in developing tailored MPN offerings for our clients in the southern African region. When Sasol turned to us to embark on this digital journey, it was a privilege for us to walk alongside them and provide them with solutions they needed to transform their operations while making a positive impact on our country's industrial sector.”

Yas Comoros secures US$27mn IFC loan to expand broadband and 5G services

Yas Comoros, a subsidiary of AXIAN Telecom, has announced a new partnership with the International Finance Corporation (IFC) to fuel the next stage of digital development across the Union of the Comoros

This collaboration will support the expansion of mobile and fixed broadband infrastructure, promoting economic advancement and greater digital inclusion throughout the islands.

Stefano Resi of Nokia discusses South Africa’s data centre growth and regional digital leadership

Stefano Resi, head of data centre sales for Middle East and Africa at Nokia, sharing insights into South Africa’s leadership role in Africa’s evolving data centre ecosystem, its unique advantages, current challenges and the road ahead for digital infrastructure across the continent

South Africa has long been a digital powerhouse on the continent, but as infrastructure demand accelerates, its role is expanding in new and significant ways.

With more than 30 million sq km, 54 countries and over 1.5 billion people, Africa represents a complex digital ecosystem—not a singular market. It is home to rising data centre activity in Nigeria, Kenya, Djibouti, Morocco and Egypt, but South Africa continues to stand apart.

According to Stefano Resi, “South Africa stands out because it is the only country connecting the two oceans and it serves as the gateway to the entire sub-Saharan region.”

But it is not just about geography. “Location alone does not define leadership,” Resi explained. “What sets the country apart is its mature legal framework, education system, and accessible business environment. These factors all contribute to an ecosystem primed for digital innovation.”

South Africa’s position as a key landing point for major undersea cables such as 2Africa and Equiano enhances its connectivity, while cities like Johannesburg and Cape Town are becoming magnets for hyperscale and colocation developments.

“These factors combine to make South Africa a fertile environment for large-scale data centre investment,” added Resi. “Already, Johannesburg and Cape Town are hosting an expanding constellation of high-capacity facilities.”

Data centre design has also evolved. While earlier models focused on simple storage and compute, modern facilities are driven by hyperscalers like AWS, Google Cloud and Microsoft Azure. Traffic now flows heavily within the data centre (east-west), requiring intelligent switching, dynamic architecture and automation.

This transformation aligns with the rise of latency-sensitive services such as augmented reality, industrial IoT and autonomous systems—services that demand a new kind of infrastructure.

“South Africa, with its dispersed urban centres and vast geography, is uniquely positioned to build a tiered architecture of core and edge data centres,” Resi explained. “These smaller edge facilities will be critical to delivering low-latency services to end users across the country.”

Yet, power instability remains a persistent challenge. Data centres consume vast amounts of electricity, and South Africa’s energy volatility poses a threat.

“Power is the Achilles heel of the digital (r)evolution in South Africa,” noted Resi. “However, this challenge can become an opportunity by accelerating the adoption of green energy sources. There needs to be a national-level commitment to energy stability if we are to meet future AI-driven demand.”

The industry must also prepare for the impact of AI. Unlike traditional workloads, AI applications require new cooling, hardware and networking standards.

“AI will reshape how we design data centres,” concluded Resi. “Inference and learning workloads place different demands on hardware, cooling, layout and obviously new network design and specifications.”

He believes South Africa will remain a central pillar in Africa’s digital transformation. “In a first phase by providing directly the data centre infrastructure for less digitalized countries, however in a second phase, when these countries will be accelerating their digital path, South Africa will continue to be the Hub and the guiding reference for the continent’s digital Agenda.”

West Africa’s DDoS threat landscape was dominated by Nigeria and Mali, according to NETSCOUT’s Threat Intelligence Report for July to December 2024, which analyses global attack trends and techniques

Nigeria faced 1,716 attacks in the latter half of 2024, a notable decline from 2,721 incidents in the first six months. Meanwhile, Mali saw a dramatic surge, with attacks soaring from 115 in the first half to 1,637 in the second half of the year.

“Web search portals and all other information services bore the brunt of attacks in Mali, with an astounding average duration of 1,197 minutes per incident,” said Bryan Hamman, NETSCOUT’s regional director for Africa. “This was followed by wired telecommunications carriers, which was also the most targeted industry at a global level during the same period, with more than 2.1 million incidents.”

In Nigeria, the main targets included telecommunications resellers and computing infrastructure providers. Interestingly, beauty salons appeared among the top ten sectors attacked, alongside wired telecommunications carriers, commercial banks, used merchandise retailers, tyre dealers, and household electronics wholesalers. “This shows once again how threat actors adapt their strategies accordingly within different countries to target those industries that are strong in individual sovereign territories,” Hamman explained.

Nigeria also experienced some of the most complex DDoS campaigns in the region, with up to 22 different vendors involved in a single attack, primarily using TCP, DNS amplification, and ICMP flood (Ping flood) methods.

Liberia ranked next with 1,189 attacks, slightly fewer than the 1,515 reported earlier in 2024. The country’s computer systems design services sector was heavily targeted, suffering 360 attacks over six months. DNS amplification was the dominant attack vector, closely followed by STUN amplification.

Ghana recorded a sharp decline in attacks in the second half of 2024, falling to 917 from 4,753 earlier in the year. The ICT sector remained most targeted, including web search portals and information services (317 attacks), wired telecommunications carriers (43), and computing infrastructure providers. Notably, footwear manufacturers were third, enduring 14 attacks during the period.

The Democratic Republic of the Congo entered NETSCOUT’s rankings for the first time, coming in fifth with 879 attacks. Hamman noted, “While the most significant attack peaked at a modest 0.74 Gbps, the complexity was notable – with up to 15 vectors used in a single attack.” Computing infrastructure providers bore the brunt, though one satellite telecommunications attack lasted an exhausting 689 minutes.

Though Cameroon was not the most targeted country with 811 incidents, nor did it experience the most complex attacks, it recorded the highest bandwidth attack in the region at 200.43 Gbps – surpassing Nigeria’s 148.77 Gbps.

Meanwhile, Côte d'Ivoire, Guinea, and the Republic of the Congo faced fewer attacks, with 495, 341, and 329 incidents respectively. Côte d'Ivoire suffered the largest attack among them at 8.66 Gbps, targeting wired telecommunications carriers. Guinea’s wireless telecommunications carriers were most pressured, while telecommunications resellers were the hardest hit in the Republic of the Congo.

“This latest data from NETSCOUT reinforces a critical truth for West Africa: DDoS attacks aren’t just increasing in frequency, but also in intensity and sophistication,” Hamman emphasized. “While nations like Nigeria and Mali face a high volume of incidents, others are experiencing powerful, high-bandwidth attacks that can cripple essential services.

“As noted previously, the ICT sector remains firmly in the crosshairs across the continent in its entirety, making it vital for organisations across the region to prioritise proactive defence strategies, invest in continuous risk assessments and engage in broader cybersecurity collaboration to stay ahead of evolving threats,” he concluded.
