On Tuesday morning, a significant disruption in Spain saw major mobile networks going offline, leaving millions without phone or internet access. The problem began around 2 AM and escalated by 5 AM, with services completely failing in key cities like Madrid, Barcelona, and Valencia. Users reported an inability to make calls, send texts, or use mobile data.
This disruption also directly impacted emergency services, making it difficult for people to reach the EU emergency number 112 in regions such as Aragon and the Basque Country. In response, local authorities provided alternative contact numbers to maintain public safety. By late morning, some services started to return, although the situation caused considerable inconvenience for many.
Spanish media reported that the outage resulted from a major technical flaw during network upgrades conducted by Telefonica, the leading operator for most of Spain’s mobile infrastructure. Landline services were significantly affected as well, causing various issues in voice-related communications. A spokesperson for Telefonica acknowledged the problem, indicating they were actively working to resolve the situation.
The Ministry of Digital Transformation monitored the issue closely and requested further information. Notably, this outage came just weeks after another significant blackout, known as the Iberian Peninsula blackout of 2025, which left Spain and parts of Portugal without electricity for nearly 10 hours. Initial theories of a cyberattack were quickly dismissed by authorities.
