A nearly six-hour telecommunications outage cut off internet and mobile phone access across the Los Pedroches region and northern Córdoba on Tuesday evening, halting local businesses and forcing cash-only transactions. The disruption began at approximately 17:30 local time and lasted until past 23:15, according to local reports.
Fiber Optic Interconnection Failure Triggers Regional Blackout
The outage stemmed from a failure in the central interconnection lines supplying fiber optic coverage to the northern zone of Córdoba. The general breakdown affected both the aerial line managed by Telefónica-Movistar and the line managed by Correos, disabling every telecommunications and internet provider relying on that shared digital backbone. Infibra confirmed the location of the fault and announced plans to file a formal complaint against its service provider. A similar fiber breakage caused widespread communications losses in the region in December 2025, highlighting recurring infrastructure vulnerabilities.
Business Disruptions and Emergency Response Adjustments
The blackout paralyzed commercial activity in multiple towns throughout the area. Retailers and hospitality venues could not process electronic payments via data phones, forcing merchants to rely strictly on cash transactions. Meanwhile, emergency services maintained operations by switching to radio communication systems, as reported by the Local Police of Pozoblanco.
