Blackout

Plan a trip.

Pick where you’re driving. Blackout forecasts the dead stretches from modeled coverage, then gives one person a link to watch you through them.

Carrier

Coverage is modeled per carrier. One carrier per trip.

Grace period

Alert after15 mins

How long we wait after you were predicted to get signal back before your watcher is alarmed. Late is normal; silent is not.

Demoing on stage? Set this to 1–2 minutes — nobody watches a green screen for fifteen.

Pick a start and a destination to run the forecast.

Coverage is a forecast, not a measurement. Browsers cannot read signal strength, so we predict from modeled data and treat anything weaker than −100 dBm as dark. Modeled coverage runs optimistic; we round against it on purpose.
