The problem was discovered at 04:00 on Monday morning and led to Nobina having to inform drivers about schedules manually.
Several counties in Sweden reported disruptions to public transportation, including Halland where bus routes were cancelled throughout the county. Problems also arose in Norway and Finland, where, among others, Yle reported on delays and cancelled departures.
Skånetrafiken reports that they still lack technical communication with several buses in the county.
It may be a delay. As long as it doesn't flow as usual, we have a message about disruptions on our website, says Theresia Swanholm, press officer at Skånetrafiken.
According to Nobina, there may be delays throughout the day.
It's too early to say that the system is stable, and that we've gone back to a normal Monday, says Niklas Torslund.
It's also too early to determine the cause behind the failure that occurred in two data centers and led to the internet being shut down.
At present, there is no indication of a cyberattack, according to Niklas Torslund.
We're working on figuring it out. The next step will be to ensure it doesn't happen again. At present, we haven't found anything that suggests it came from outside.
