Many things are only obvious until you try to spell out the details. Do installed cables, switches etc. have a shorter lifetime in the cities, such that they'll be replaced more often and thus will tend to be newer and better? Does fibre face less competition from installed alternatives in the cities than in the countryside, such that digging is more likely to be profitable? I live in the city. This street was supplied with 20-100Mbps DSL early on. Now the ISPs don't want to dig here, because selling fibre against the installed DSL connections is so difficult.
