@Prometheus, the answer to v3g's semi-rhetorical question there, is that Transtel & Eskom leveraged the railway network as well as electricity poles & pylons, i.e. the fibre optic cabling is above ground, whereas digging up roads & pavements is considerably more expensive and takes much longer.When did Transtel/Eskom start building their respective networks?
Why do you think it was possible for Transtel/Eskom to lay thousands of Km's of fiber?
