CityFibre is only available through wholesale ISP's. Other smaller alt-nets (such as the one I work for - Netomnia (including Brsk/YouFibre)) is gearing up to provide wholesale access.

In the UK there are even aggregators like Fibre Café [1] that makes it easier for ISP's to connect through multiple networks.
