Simulated scenario — the storm is invented. This is Signal Blackout's deterministic offline demo, not a live view and not a forecast. The storm warning that drives it was made up by the demo because no Met Office warning was active when the fixtures were captured. The power cuts underneath it are real incidents captured from the UK Power Networks and National Grid Electricity Distribution public feeds on 10 August 2026, replayed against a scenario clock of 2026-08-10 01:30 +01:00. Nothing here is happening now.

Signal blackout

When the power cut takes your phone too. Phone masts run on batteries. In an extended power cut those batteries run down, and mobile signal goes with them — which is exactly when people need to call for help.

Simulated scenario. The power cuts below are real incidents from the UK Power Networks and National Grid Electricity Distribution public feeds, captured 10 August 2026. The storm warning is invented, because no Met Office warning was active at capture time.
