Background on Telefónica and its Relevance

Telefónica, a leading Spanish telecommunications company, plays a crucial role in connecting millions of individuals and businesses across Spain. As the second-largest telecommunications provider in the country, following MasMovil (formerly known as Orange), Telefónica offers a wide range of services, including fixed-line telephone, broadband internet, and mobile communications.

Recent Network Upgrades and Communication Disruptions

On Tuesday, Telefónica announced that ongoing network upgrade projects had caused partial communication disruptions for fixed-line telephone and internet services in certain regions of Spain. This incident occurred approximately three weeks after the country experienced a significant power outage on April 28, which affected both Spain and Portugal.

Telefónica issued a brief statement informing the public that their teams were diligently working to restore services. Fortunately, emergency lines (112) in the affected areas had already resumed functioning by late Tuesday morning, following interruptions since early morning.

Impact on Specific Regions

According to the Downdetector website, the reported disruptions primarily affected fixed-line internet services in Aragon, the Valencian Community, Andalusia, Extremadura, the Basque Country, and Navarra.

Comparison with Other Providers

It’s important to note that other major telecommunications providers in Spain, such as MasMovil and Vodafone, were not affected by these disruptions. Furthermore, Telefónica’s mobile services appeared to operate without any issues during this time.
