“Grid down” gets thrown around as one single catastrophic event, and that framing does more harm than good when it comes to actually planning. Cell service, internet, and the power grid fail on different timelines and for different reasons, and almost every real event most of us will actually experience is a partial, temporary version, not the total collapse the phrase implies.
Cell and Internet Fail Long Before the Power Grid Does
Cell towers have battery backup measured in hours, not days, and they get overwhelmed by call volume well before their batteries even run out. Internet service depends on that same cell infrastructure for a lot of people, plus whatever is happening at the ISP’s local equipment. Power can stay up while both of those are already struggling, which is exactly the gap radio fills.
Most Outages Are Hours, Not Months
The overwhelming majority of power and comms disruptions most people ever experience resolve within hours to a few days. Planning exclusively for a permanent grid collapse, while satisfying as a thought experiment, leaves you underprepared for the far more likely short, disruptive event that is actually going to test your plan.
The Realistic Middle Scenario Nobody Plans For
A multi-day regional outage from a storm, wildfire, or infrastructure failure is far more likely than a permanent collapse, and it stresses a comms plan in a way a one-hour blip never will. This middle scenario is where most families’ plans actually break, not from lack of gear but from a schedule and battery plan that only ever got tested for a few hours at a time.
Plan for the Likely Case, Not the Movie Version
A good plan, like the one I lay out in what a real SHTF communications plan actually looks like, scales from a short disruption up to a multi-day event without requiring completely different gear or a completely different mindset. Build for the realistic middle, and the rare worse case is just more of the same plan run longer.
