If your thinking of a wires only internet connection, say avg £25 a month for home fibre, or business fibre for around £50 a month. But there there is a lot more an ISP does than just sell broadband, or sell leased lines or other type of wan connectivity
I don't see how its that surprising really, we are just doing what we have been doing for a long time, but faster :\ and with more advances in network technology. Your just hopping off one network to the next, to the next, and you find yourself on the other side of the world
Ie if you using level3 as a peering or carrier and sent a trace route to the USA, you would see go through a few hops at ISP level, hit a level3 border routers maybe, hit a level3 router on the UK to USA transatlantic crossing fibre, then next hop would be USA side and it would be routed towards your destination
What does amaze me is looking at some of the maps of the undersea fibre runsin massive ducting , I seen a video of a ship using this cable thing to repair a section
Most ISPs business wise make most of their money from end to end managed services, managed firewalls, switches, routers, virtualized hosting, colocated hosting, cloud platforms, DaaS, SaaS, etc etc, security, the list gets big, when you get in to them realms wires only services that becomes small fish
Commercial home based isps sometimes offer business packages, or even sometimes hosting . but generally they thrive on manipulating and owning a big % of home broadband and phone lines ie sky, plusnet, BT
