Widespread disruption in Denmark after mobile network outage

Severe outages for one of Denmark's largest mobile networks caused disruption for emergency services, with investigations ongoing to identify the cause.

At least one hospital was forced to reduce non-critical care after one of Denmark's largest mobile networks suffered severe outages.

TDC Net said the problems were likely due to an update carried out in the past day and it had no reason to believe a cyber attack was behind the disruption.

While the network was down, people couldn't contact emergency services and security services in some areas patrolled streets in case anyone needed help.

According to Danish media, trains and buses in some parts of the country experienced delays because of signalling issues, with chaos in stations and passengers stuck on trains.

The Centre for Cyber Security, the country's national IT security authority, and the Danish Defence Intelligence Service couldn't confirm if the mobile network and transport signalling issues were linked.
