In a world heavily reliant on technology, the question arises—can the internet withstand the test of a prolonged blackout like the one currently sweeping across Spain and Portugal? As power is stripped from cities, the backbone of modern communication faces its ultimate challenge.
Data Centers: The Last Line of Defense
During a power outage, large data centers stand as bastions of resilience. Equipped with their own clusters and backup systems, they possess the ability to operate indefinitely. However, they are not invulnerable, as the internet’s health heavily depends on smaller intermediate clusters dispersed across cities.
The Weak Link: Intermediate Clusters
The intricate web of the internet relies heavily on intermediate data switches scattered throughout urban environments. Arturo Azcorra, deputy director of Imdea Networks, describes their importance: “The internet works because there is intermediate equipment distributed throughout cities.” These switches, crucial for maintaining connections, have a limited lifespan independent of power.
Vodafone’s Struggle to Stay Afloat
Telecommunications companies like Vodafone report partial success in maintaining network operations using backup generators. Currently, Vodafone Spain’s network remains 70% active. Yet, their operational sustainability is directly tied to how long the blackout persists.
Public Usage and Responsibility
As per Vodafone’s statement, citizens are encouraged to use mobile communication services sparingly to prevent overloading the limited network. Other telecom providers, though integral, have yet to provide updates on their current network status.
The Wi-Fi Conundrum
Another looming question is whether individuals can count on their phones during such crises. According to Azcorra, without Wi-Fi access, mobile phones struggle to connect or make calls, as base stations simply cannot function without power unless close to critical locations with independent power sources.
A Glimmer of Hope
While the situation may seem dire, certain measures can be a beacon of light amidst the darkness. Wi-Fi access in office buildings and connections near critical locations such as security forces headquarters may provide temporary relief, enabling communication until power is fully restored.
As stated in EL PAÍS English, the blackout in the Iberian Peninsula highlights the fine balance between technology and infrastructure and the pressing need for robust backup systems.
