Norway’s DSB says its household self-preparedness campaign began in 2018 with a three-day message. In May 2024 the recommended period increased to one week. An updated brochure followed in autumn 2024.
The authority describes preparing for interruptions to electricity, water and mobile networks, with public resources prioritised for people who cannot manage without help.
A policy change, not an attack timetable
The change is real, but a household planning period does not state the probability or date of a future emergency. It also shows why describing every country’s advice as exactly 72 hours is inaccurate.
