Where the attack comes from is unclear.

- It is not something I can comment on right now, I have no information about it, says Richard Karlsson.

Whether the disturbances at the other regions, the hospitals and 1177 had to do with an IT attack is also unclear.

On Region Stockholm's website, it was announced that the problems with 1177 were due to a malfunction.

The website 1177.se is used, among other things, for healthcare information and for patients to book an appointment with their healthcare centre.

1177 is operated by the company Inera, which is owned by SKR.

Inera's website was also down.

The website of the Västra Götaland region and the Sahlgrenska University Hospital are still not accessible.
