Emergency responders had to rely on social media to share alternative contact numbers while authorities in Catalonia and Extremadura confirmed that their emergency lines were disrupted but expressed that contingency plans were in place. By late morning, Telefónica declared that all systems were restored, with the country's digital transformation minister praising the company's quick response.

Telefónica serves over 41 million customers and largely maintains a monopoly over Spain's landline services. Outage tracking service Downdetector noted spikes in issues for other telecom providers as well, such as Movistar, O2, and Orange.

This incident follows a major incident last month where an 18-hour blackout affected millions, paralyzing transport and businesses. The previous outage has already drawn public criticism directed at government officials concerning their management of such infrastructure crises, which have reportedly cost the economy millions of euros.
