Hospitals in the Capital Region of Denmark have suffered a major breakdown in IT systems on Friday, regional authorities said.

The breakdown reportedly started at 07:20am Friday and affected computers, telephones and call centers.

The Capital Region of Denmark, the easternmost region of the country, has a population of about 1.8 million people. It includes the municipality of Copenhagen, the Danish capital and the most populous city.

“Capital Region of Denmark hit by network outages [in the IT systems]. Error localized and networks are expected to work again soon,” local authorities tweeted.

Region H ramt af netværksnetbrud. Berører PCer, Sundhedsplatform og telefoni. Fejl lokaliseret og netværk ventes oppe igen snart. Opdateres. — Region Hovedstaden (@RegionH) August 4, 2017

Later they said that the problem of the IT breakdown had been resolved, but some functions are still not working.

“It's still too early to say whether [the breakdown] is going to affect today's program of planned operations,” an official from the Capital Region authorities told TV 2 News channel.

Netværksnedbruddet er i store dele løst nu, men der er stadig funktioner, der ikke virker. Vi arbejder på at løse det. Opdateres. — Region Hovedstaden (@RegionH) August 4, 2017

According to TV 2 sources, the planned operations will be delayed.

It is still early to say if a cyberattack precipitated the IT breakdown, a spokesman for the region told Reuters.
