Spain was exporting power to France and Portugal at the time of the outage, leading to impacts on its neighbors. Portuguese grid operator E-Redes attributed the outage to "a problem with the European electricity system" and said it had to cut power in specific areas to stabilize the network.

In Spain, Internet traffic dropped 60 percent compared to the previous week as the power grid failed, falling to approximately 80 percent below the previous week within the next five hours. Traffic from the top five ASNs in Spain fell between 75 and 93 percent in the hours after the power outage began.

As well as local operators and international colocation companies, hyperscalers including Meta, Amazon, and Microsoft all have a footprint in Spain. While any data center operator worth its salt will regularly test its backup operations, its not uncommon for issues to arise during real-world events.

According to Red Electrica data cited by Reuters, Solar photovoltaic (PV) accounted for 59 percent of Spain's electricity at the time of the blackout, wind nearly 12 percent, nuclear almost 11 percent, and combined cycle gas turbine (CCGT) plants 5 percent.

It has suggested two incidents of power generation loss, possibly from solar plants, in Spain's southwest that caused instability in the electric system and led to a breakdown of its interconnection with France, and had a cascading effect across the country.
