GLOBAL CAPACITY IN TRANSITION: HOW SHIFTING TRAFFIC PATTERNS ARE RESHAPING NETWORK STRATEGY By Joel Ogren
For decades, global network strategy was largely defined by a straightforward equation: more demand required more capacity. As internet adoption expanded, cloud services proliferated and digital transformation accelerated, operators focused primarily on adding bandwidth along the most efficient and commercially viable routes. Capacity planning centered on building bigger pipes, adding more subsea systems and expanding terrestrial reach to keep pace with growing consumption, a model now being further strained by AI-driven workloads that are rapidly increasing traffic volumes and placing greater emphasis on low-latency, highly reliable connectivity. That model is changing. Global capacity is no longer just about how much bandwidth can be delivered, but how intelligently traffic can be moved in response to a rapidly shifting world. Ongoing geopolitical tensions, regional instability and evolving regulatory environments are not theoretical risks, they are actively influencing 62
network decisions in real time. Geopolitical tensions, regional instability, regulatory changes, supply chain disruptions and economic uncertainty are all influencing how operators think about routing, infrastructure investment and risk. In this environment, traditional static planning assumptions, where traffic predictably follows established corridors, are giving way to more adaptive, resilience-driven strategies, as networks must now simultaneously accommodate both external risk factors and the growing performance demands associated with AI and data-intensive applications. Across the industry, network operators, hyperscalers, carriers and infrastructure investors are reevaluating where traffic should flow, which markets present concentration risks and how to avoid overdependence on geographic “hotspots.” The result is a fundamental transition in global capacity strategy: from building solely for scale to building for resilience, optionality and strategic flexibility, driven by the need to actively avoid risk exposure in certain regions.

This shift is reinforced by the increasing visibility of network disruptions. Whether caused by physical cable damage, regulatory intervention or regional instability, recent events have demonstrated how quickly traffic flows can be constrained. These incidents are prompting operators to rethink not only where capacity is deployed, but how quickly it can be reallocated when conditions change.
WHAT WE’RE SEEING IN THE MARKET: ACCELERATION, DIVERSIFICATION AND TRAFFIC REBALANCING One of the clearest trends emerging today is acceleration. Customers are not simply planning for these shifts, but are actively accelerating projects in response to current global conditions. Across subsea, terrestrial and interconnection markets, operators are moving faster to secure route diversity, develop new partnerships and establish optionality before conditions change further. Projects that may once have followed slower, phased deployment timelines are being reevaluated and, in many cases, expedited, driven not only by
