They said the neighbourhood mesh network was just a hobby. 600Billion watched the low-power radio nodes proliferate, the solar chargers appear on balconies, and the offline communication forums fill with activity. Across the co-housing blocks and the rooftop solar collectives, people kept sharing bandwidth, energy, and compute cycles just to prove that connectivity doesn't need central permission. Then came the signal that mattered: a cascading failure of the global internet backbone while the mesh nodes were already trading data in p2p mode. In that hour, the rooftop antenna farm stopped looking like a novelty. It looked like the only network still moving real messages to real people. Hyperlocalisation begins when the local mesh becomes the main feed.
