Central service problems.
The cooling system at USIT is having issues, something which has caused a number of services to fail. Email, user administration (brukerinfo/bofh/Cerebrum), Feide, nettskjema, and other services are affected.
The situation is treated as serious and there is a lot of staff on site to try to remedy the problem. There is currently no ETA on when the services will return. See also http://www.uio.no/tjenester/it/aktuelt/driftsmeldinger/problemer-med-epostsystemet.html (in Norwegian).
