Telia's last night's network failure was due to a disturbance in connection with the renovation work, says Timo Saxén from the company's communications.
According to Saxén, the fault was in the connections connected to business services.
From the company's ordinary subscriptions, it has been possible to call all numbers during the fault, including the emergency number.
The number of subscriptions covered by the fault was 200,000–300,000. In total, Telia has about three million mobile subscriptions in Finland.
Telia has notified the authority, ie the Finnish Transport and Communications Agency Traficom.
The disturbance lasted a couple of hours at night between one and three o'clock.
