Scenario guide

Communications outage preparedness

Power cuts can disable home routers immediately and may eventually affect mobile networks. A charged phone is useful, but a battery or wind-up radio can provide another path to official updates when networks fail.

Local guidance always takes priority.

During a real incident, follow current local government, emergency-service, utility and public-health guidance for your location. Local evacuation, boil-water, do-not-drink, shelter and safety instructions override this website.

Try it interactively

Turn communications OFF and electricity OFF to make backup phone energy relevant in the plan.

Run this scenario
Safety: Keep important numbers and essential instructions on paper as a low-tech backup.

Why this page exists

Generic checklists often hide dependencies. Home Resilience Check is designed to make those dependencies visible and keep the underlying assumptions auditable.

Source-led, not fear-led

Planning guidance is based on recognised public authorities. During a real event, current instructions from emergency services, utilities and local government take priority over this planning page.

Communications resilience is more than mobile signal

A mobile or internet outage can remove several routes to information at once. Home broadband equipment normally needs local electricity, mobile networks can become congested or lose local coverage, and battery life becomes more important when devices search repeatedly for weak signal.

Build an information fallback

The calculator treats a battery or wind-up radio as a core backup route for official information. It also keeps phone-energy planning visible when electricity is unavailable at the same time. A written list of emergency contacts, important account numbers and local utility details reduces reliance on a single online service.

Combine failures rather than testing them in isolation

The most useful scenario is often communications plus another outage. For example, a power cut can remove home Wi-Fi while a wider incident overloads mobile networks. Use the combined scenario switches to see whether stored power, lighting and information backup become simultaneous gaps.

Do not treat the result as a live network status

Home Resilience Check does not monitor carrier coverage or local emergency broadcasts. During a real incident, use any functioning official channel available to you and follow instructions from emergency services and public authorities.
