How Would Russian Submarines Cutting Atlantic Internet Cables Impact Global Connectivity?

With advancements in technology and the increasing reliance on the internet, the potential disruption caused by a complete shutdown or rerouting of Atlantic internet cables poses significant concerns. In a scenario where Russian submarines were to intentionally cut these critical undersea cables, the impact on global internet connectivity would not be seamless. However, the internet's design for redundancy and resilience offers some measures that could mitigate the effects of such a massive disruption.

Redundancy in Internet Infrastructure

The internet is built on a vast network of interconnected cables, including undersea cables that connect continents. This interconnectedness means that if one or more cables are damaged, traffic can often be rerouted through other available paths, provided those paths are operational. This inherent redundancy ensures that internet traffic is not solely reliant on a single route. For example, data can be rerouted to Pacific cables or even via satellite communications, though this process requires significant human and technological intervention.

Routing Protocols: The Role of Border Gateway Protocol (BGP)

The internet uses routing protocols such as Border Gateway Protocol (BGP) to manage how data is routed across the network. BGP allows routers to communicate and share information about the best paths to reach various destinations. This dynamic nature of BGP can help find alternative routes if a major route becomes unavailable. However, this redirection process is not instantaneous and relies on the availability and proper configuration of alternative paths.

For instance, if the Atlantic cables were severed, BGP could help redirect traffic through operational Pacific cables or even via satellite networks. But this process would require active monitoring and adjustment by network operators to ensure that the alternative routes are properly set up and optimized for the sudden increase in traffic.

Impact of Damage

Severing the Atlantic cables would likely result in significant delays and congestion as the system attempts to reroute traffic. While some data might be successfully rerouted via existing Pacific routes, the overall performance and connectivity would heavily depend on the remaining infrastructure's capacity to handle the traffic. The disruption could lead to a decrease in internet speed, increased latency, and potential outages.

For non-technical entities, this means that websites would load slower, video streaming would be more erratic, and real-time communication could be significantly disrupted. These issues would affect businesses, educational institutions, and governmental operations globally.

Human Intervention and Management

In practice, network operators would need to closely monitor the situation and manually intervene to manage the new routing requirements. They would adjust routing policies to optimize traffic flow and ensure that alternative paths are prioritized over existing routes that may be experiencing congestion. This proactive management would be crucial to minimize the impact on internet users and critical services.

Moreover, network operators might need to deploy additional resources and technologies to handle the surge in traffic. This could include launching emergency repairs to repair the damaged cables or investing in new infrastructure to increase the capacity of the alternative routes.

Limitations and Challenges

Even with the built-in redundancy, the capacity of alternative routes may not be sufficient to handle the traffic that typically flows through the Atlantic cables. Extensive damage could lead to significant outages or slowdowns, making it challenging to maintain the same levels of performance and connectivity.

It is important to note that while the internet has mechanisms for rerouting traffic, significant human oversight and intervention would likely be needed to effectively manage the situation following a major disruption like severed Atlantic cables. The internet's robust nature and its adaptability to changes are essential, but they are not immune to the impacts of such a deliberate and targeted disruption.

Conclusion: The internet's design for redundancy and resilience offers some measures to mitigate the impact of a major disruption. However, a complete severing of Atlantic internet cables would likely require extensive human intervention to reroute traffic effectively, manage congestion, and ensure ongoing connectivity for global users.
