'Hyperbolic map' of the internet will save it from COLLAPSE

International computer boffins are warning that the internet may "collapse" at some point within the next decade. They propose the use of a new routing method based on hyperbolic geometry, and have devised what they call a "hyperbolic atlas" of the entire net to aid in this plan. Hyperbolic map of the internet.
