Due to signaling problems, train and bus services were delayed in some parts of the country.
One of Denmark’s largest mobile networks experienced widespread outages on Thursday, preventing people from contacting emergency services and forcing at least one hospital to limit the provision of medical care to essential cases. Bus and train traffic was also disrupted due to signaling problems, but it is not clear whether these two incidents are related in any way, writes TASR according to the AP report.
The network provider, Danish telecommunications company TDC Net, reported on Thursday afternoon that the problems were likely caused by a system update that took place in the past 24 hours. She added that she has no reason to believe that cyber attacks could be behind the outages.
The network has returned to normal operation
The company announced in the evening that it had temporarily fixed the system so that its customers could make calls, albeit with reduced sound quality. At the same time, she urged customers who needed to call the emergency line 112 to remove the SIM card from their phone before making such a call.
It later said that the network had already returned to normal operation and that it would investigate the cause of the failure.
In addition, Danish media reported that due to signaling problems, train and bus services were delayed in some parts of the country, there was chaos at stations and many passengers were stuck on trains for long periods of time. Neither the Danish Cyber Security Center nor the Secret Service have yet been able to determine whether the two incidents are related.
