Static snapshot captured 2026-09-02 23:08:39 UTC. This page is a frozen copy of Signal Blackout's live national view. Every power cut on it was a real, unplanned incident published by a UK electricity distribution network at that instant — and every one of them has almost certainly been fixed since. Nothing on this page updates. The live version polls the eight UK distribution-network feeds and recomputes on each run; it runs locally (python -m signal_blackout live). Do not read this page as the state of the grid now.

Power cut data: the operators' own public feeds — UK Power Networks (CC BY 4.0), National Grid Electricity Distribution (licence not stated by the publisher), SSEN (CC BY 4.0), Northern Powergrid (Northern Powergrid Open Data Licence v1.0); see the full licence line in the footer.

Signal blackout — UK view, frozen snapshot

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. Every power cut below is a real incident reported by a real distribution network.

AT CAPTURE TIME (2026-09-02 23:08:39 UTC): 6 of 8 feeds were reporting (2 absent, 6 live); the newest incident update was 43 seconds old.

At capture time we could not see these areas: North West England; central and southern Scotland, Merseyside, Cheshire, North Wales, Shropshire. That is not the same as no power cuts there. Treat those areas as unknown.
