Denmark is in a state of crisis after the networks of the country’s major telephone operators were shut down at the same time; A catastrophic failure that affected both commercial and government services, including public transport and emergency services.

The situation comes at a time of high political tension due to a possible sabotage campaign against electricity and telecommunications cables that connect the Scandinavian countries to the rest of Europe. Last week, Europe strengthened the protection of underwater power cables, given the possibility that Chinese or Russian ships could cut them to affect normal power supplies.

However, the Danish government has not yet confirmed that this chaos is the result of such sabotage, and instead everything points to a more fundamental failure: a software error. This has been confirmed by TDC Communications, the country’s largest telecommunications provider, whose manager Lasse Bjerre Sorensen told television channel TV2 that the problem This happened due to a software update. Which was implemented last Wednesday.

It is going on. It is still unclear why the rail system was also affected by the mobile network failure, Sorensen said, adding that TDC is working with international experts to investigate the error.
