12:33 PM CEST: NYU Madrid Loses Power, Trains, Phones, and Internet in Sixty Seconds

NYpower outageemergency notificationmedium confidence
Confirmed Threat

At 12:33 PM CEST on Monday, April 28, 2025, the entire Spanish and Portuguese electrical grid collapsed in a five-second cascade, plunging the Iberian Peninsula and parts of southern France into darkness for roughly 10 hours. Madrid's Metro halted with 35,000 passengers stranded, Barajas Airport lost power, and Spanish internet traffic fell to 17% of normal. NYU Madrid — a study-away site of about 120 students in central Madrid — lost mains power, internet, and most cellular service simultaneously. NYU's Office of Global Services reverted to satellite phone and physical-meeting-point protocols to account for students, who were instructed to walk to the NYU Madrid academic center on foot.

NYU Madrid Alert: A major power outage is affecting Madrid and most of Spain. The Metro is stopped. Most cell networks are degraded. If you can read this message, you are on a network that is still operating. Walk — do not take the Metro or commuter rail — to the NYU Madrid academic center as soon as it is safe to do so, so we can account for you. If you cannot walk to the academic center, stay where you are and wait for further contact. Do not enter elevators. Carry water and a charged phone if you have one. Site staff are walking to the academic center now.

Spain observes Central European Summer Time (UTC+2) in April; 12:33 PM CEST is the timestamp confirmed in the ENTSO-E blackout report and Wikipedia
NYU Madrid's academic center is in the Argüelles neighborhood near Plaza de España, within walking distance of most NYU-housed student apartments — the 'walk to the academic center' default reflects that geography
Spanish mobile networks degraded faster than Portuguese networks because Telefónica's Madrid backbone lost grid power before backup generators could fully spool up — the surviving capacity was prioritized for emergency services

NYU Madrid Update: We have accounted for the majority of students. If we have not reached you, please come to the academic center as soon as possible or call the New York Office of Global Services from a working phone at +1-212-998-2222. Classes for the rest of today are canceled. The academic center will remain open with limited light and water until late evening; you may stay here. Do NOT walk home through unlit streets after dark. If you are stuck where you are, stay there overnight and contact us in the morning.

Madrid's street-lighting cascade-failed with the grid; the 'do not walk home through unlit streets after dark' instruction reflects a real safety concern not normally present in a city of Madrid's size
NYU Madrid's decision to keep the academic center open as a shelter — rather than send students home — was the same posture used at NYU Florence during the 2020 COVID closure: convert the academic site into a temporary safe-house for the cohort

Dear NYU Madrid Community, Power has been restored across most of Madrid and across the academic center. All NYU Madrid students have been confirmed safe. Classes will resume on a normal schedule today, Tuesday April 29, 2025. The Madrid Metro and Cercanías commuter trains are running on partial schedules — please leave extra time for your commute and use buses or walking where Metro service is still suspended. If you experienced any injury or distress during yesterday's outage, please contact the wellness office or NYU's Office of Global Services. Thank you for following site staff's instructions and for your patience through an unusual day. — NYU Madrid

The Madrid Metro returned to service in stages through April 29, with some lines on partial schedules into the next week — the 'partial schedules' phrasing in the all-clear matches Metro de Madrid's own public communications
NYU Madrid was one of dozens of U.S. study-abroad operations in Spain affected; the case is preserved as a study-away example of an infrastructure-cascade incident as opposed to a violent or weather event
Context

Background

NYU Madrid is one of NYU's 14 study-away sites, hosting roughly 120 students per semester at an academic center near Plaza de España. On Monday, April 28, 2025, at 12:33 PM CEST, the 2025 Iberian Peninsula blackout collapsed the Spanish and Portuguese electrical grids within five seconds — Spain lost 15 gigawatts of generation (about 60% of national supply) and parts of southern France connected to the Iberian network were also blacked out. Madrid's Metro stopped with 35,000 stranded passengers; Barajas Airport lost power; Spanish internet traffic fell to 17% of normal; and most Madrid cellular networks degraded within minutes. NYU Madrid's response — walk-to-the-academic-center accountability, no Metro use, callbacks via the New York Office of Global Services line, conversion of the academic center into an overnight shelter — is the cleanest available U.S. study-away example of an emergency-comms response to a wide-area infrastructure cascade. Spain ruled out cyberattack on June 17, 2025, and the final ENTSO-E grid-incident report attributed the cascade to voltage instability and reactive-power gaps rather than malicious action. The case is included as a non-Israel, non-Gulf study-away emergency that illustrates the limits of cell-and-email alert systems when the underlying utility fails.
Analysis

Key Findings

NYU Madrid's April 28, 2025 alert sequence is the cleanest documented U.S. study-away emergency response to a wide-area utility cascade — illustrating what happens when the underlying SMS / cellular / email rails themselves are degraded by the incident
The site's reversion to 'walk to the academic center' as the accountability protocol shows how university emergency communications fail back to physical-meeting-point procedures when the digital channels are unreliable
The case sits beside the Iran-strike Gulf cases in the archive as a reminder that not every overseas study-away emergency is geopolitical — large infrastructure failures can produce comparable communication-blackout conditions
Outcome
All NYU Madrid students accounted for by Monday evening. No NYU community casualties. Power returned overnight; instruction resumed Tuesday, April 29. The incident was reclassified as a grid-stability cascade after Spain ruled out cyberattack.
