Connecting South Asia: The Impact of the Digital Silk Way

A new fiber-optic cable project spanning the Caspian Sea is poised to reshape international data travel and connectivity for South Asia. The Digital Silk Way initiative, launched by NEQSOL Holding, aims to create a robust network linking markets in Central and South Asia with Europe through Azerbaijan and Georgia.

The Necessity of Reliable Internet Connectivity

In September 2025, a significant disruption occurred in the Red Sea when several submarine cables were damaged, leading to immediate consequences in South Asia. Cloudflare recorded a staggering 25–30% drop in internet traffic in Pakistan's Punjab and Sindh provinces within hours of the incident. The Pakistan Telecommunication Company had flagged concerns regarding the SEA-ME-WE-4 and IMEWE cables, predicting that service degradation would impact peak usage times.

This incident underlined an ongoing challenge for businesses in the region: despite an ability to purchase additional bandwidth, companies remained vulnerable to cable failures occurring far from their immediate locale. The robustness of these connections greatly relies on the availability of alternative pathways, particularly those that don’t share the same geographic risks.

The Vision Behind the Digital Silk Way

NEQSOL Holding's Digital Silk Way initiative is a response to such challenges. The project is a long-term vision aimed at establishing a fiber-optic transit network to foster improved access to European and Central Asian markets. Kirill Rubinski, the CEO, highlights the importance of reliable market access for South Asia's digital economy, stating, "The Caspian crossing provides a vital foundation to enhance our service offerings for operators in the region."

This development raises an essential question: How will infrastructure across the Caspian improve connectivity for South Asian enterprises?

Current State of International Connectivity

South Asia’s existing international connectivity primarily links its coastal regions to Southeast Asia and Europe. For instance, the SEA-ME-WE-5 subsea cable, which spans approximately 20,000 kilometers, connects Singapore to Europe with additional links to Pakistan, Bangladesh, and Sri Lanka. While these systems grant operators several pathways to the international network, a point of concern arises deeper along the route, where many cables rely on pathways through the Red Sea and Egypt.

TeleGeography's analysis in January 2024 indicated that over 90% of Europe-Asia capacity traversed the Red Sea, showing the heavy reliance on a few key systems. While rerouting can help maintain service during disruptions, the need for viable alternatives with sufficient capacity can be a bottleneck, especially during crises.

Recent disruptions have shown that regional unrest can further complicate recovery efforts. For example, in February 2024, damage attributed to conflict-related activities in the region showcased the vulnerabilities inherent in existing networks.

The Trans-Caspian Cable and Its Advantages

The Trans-Caspian project, developed by AzerTelecom International in collaboration with Kazakhtelecom, plays a crucial role in enhancing connectivity. Covering around 380 kilometers, it connects Kazakhstan and Azerbaijan and integrates seamlessly with other terrestrial and submarine networks. With recent completion milestones achieved, this crossing aims to diversify the existing routes and offer alternate paths for data traffic.

Emil Masimov, chairman of AzerTelecom’s board, emphasizes that having different routes is critical. “Two cables can still share the same vulnerabilities if they traverse similar corridors. The Caspian crossing introduces a new pathway, allowing for improved flexibility in how operators can connect to Europe and respond to disruptions,” he shares.

Enhancing Resilience Through Diverse Options

The advent of this new route is particularly beneficial for South Asian telecom operators, as it opens up additional options for negotiating international capacity and planning backup connections effectively. For data and cloud service providers, it presents another avenue to facilitate connections with global networks.

Rubinski underscores the significance of route diversity, stating, “For software companies serving international customers, maintaining service continuity is paramount. We aim to collaborate with operators to enhance resilience through this initiative.”

However, the successful realization of this potential hinges on establishing adequate connections and agreements that allow South Asian operators to utilize the new segment effectively. The end commercial viability will be determined by the cost-effectiveness and performance of the associated networks.

Moving Forward with the Digital Silk Way

The experiences of South Asian nations during the Red Sea disruptions provide a clear context for the necessity of the Caspian project. The goal is to establish a practical alternative route that enables greater stability and reliability in digital services. Rubinski emphasizes that success will be measured by the extent to which operators gain meaningful choices and their customers experience enhanced service reliability.

In conclusion, the Digital Silk Way initiative aims to create substantial opportunities for South Asian businesses by enhancing connectivity and resilience in the digital landscape. With continued efforts to forge partnerships and establish effective networks, this venture has the potential to revolutionize data travel in the region.
