A massive power outage hit the entire territory of Spain, Portugal and parts of southern France at around 12:30 today.
The reasons for the outage - which is still ongoing (although power has been restored in some areas) are not yet known, although there have been some bizarre theories.
According to Portuguese network operator Ren, quoted by Reuters, the reason is related to a rare atmospheric phenomenon: due to extreme temperature changes in the interior of Spain, abnormal fluctuations occurred in very high voltage lines, a phenomenon known as "induced atmospheric vibration".
For now, official sources from Spain, Portugal and the European Union explain that there are no indications suggesting a cyberattack: "There is no indication that the power outage was provoked," said Spanish Vice President of the European Commission Teresa Ribera.
The governments of Madrid and Lisbon have called emergency meetings in an attempt to coordinate the response to the power outage.

A graph from Spanish grid operator Red Eléctrica Nacional shows the power curve dropping like a knife at 12:30 p.m. Red Eléctrica said it could take "another 6-10 hours" to return to normal, while the Portuguese operator said the "complexity of the phenomenon and the need to rebalance electricity flows at an international level" lead to fears that "full normalization of the grid could take up to a week."
Paralysis and chaos of transport and lines
The consequences were immediate and very serious. Telephone lines were cut throughout Spain and Portugal.
The rail system has been paralyzed, with the Spanish national network announcing that all trains have stopped at stations and there are no departures.
Barajas Airport in Madrid and Lisbon Airport in Portugal were also hit; the Madrid and Barcelona metros have been halted.
Traffic in the capital is also in chaos; problems have also been reported in Seville, Barcelona, Valencia, Pamplona and the rest of the country.
The Spanish traffic authority has asked the population not to use the car unless absolutely necessary. / Corriere Della Sera
