From TFA:

> Det har siden kl. 01 mandag 3. august pågått et tjenestenektangrep (DDoS) som rammer ID-porten som driftes hos Digdirs driftspartner Vivicta.

> Since 0100 hours Monday August 31st there's been an ongoing DDoS attack which affects the ID-Portal which is run/hosted by DepDig's (Department of digital services') service provider Vivicta.

(My translation)

Ed: just realized Vivicta is TietoEvery with a haircut and new shoes:
