On April 28, 2025, a massive power outage swept across Spain and Portugal, severely disrupting transportation, communications, and internet services.
The blackout was attributed to a rare atmospheric phenomenon causing oscillations in high-voltage lines, which led to synchronization failures across the European grid.
Internet traffic in Spain immediately dropped by over 60% and later plummeted to 80% below the previous week's levels within just a few hours, highlighting how dependent digital infrastructure remains on stable energy supply.

While there were no direct reports of Bitcoin network disruptions, the incident has reignited concerns about the resilience of Bitcoin's infrastructure in the event of large-scale power failures. Experts stress the importance of decentralized nodes and offline backup solutions to maintain blockchain operations during regional outages.
Spanish authorities have launched an official investigation into the cause of the blackout, with early findings suggesting that a cyberattack is unlikely.
