State-owned Bane Nor, Norway's equivalent of the Swedish Transport Administration, told Norwegian broadcaster TV 2 that problems with its communication system, which brought all train traffic in the country to a complete halt, were linked to problems at Telenor.
The problems also made it difficult to reach Norway's three emergency numbers: 110, 112 and 113.
At 6:30 p.m., Telenor announced that text messages and mobile data services were working as usual and that the emergency numbers could once again be reached. Half an hour later, train operator Vy said train services were expected to resume shortly.
It is unclear what caused the problems, but Aftenposten reports that Telenor says there are no signs of a cyberattack.
