Another cable at the bottom of the Baltic, between Sweden and Lithuania, was broken a day before Cinia's cable was damaged. It was repaired on Thursday evening, according to Arelion, the Swedish firm that manages the cable. That cable is now operating at full capacity, Arelion told news service STT.
