I live and work in the W1 postcode in London. Yup, London's properous business heart, with its Mayfair hedge funds and all that. Pretty much the 'first third' by anyone's measure. In fact, I live next door but one to our telephone exchange, so close it explains why I can get a staggering 12Mbps download speeds. Prospects for BT fibre in ANY form? Zero. Sure, I can get my own leased line for £400 a month but that's a tad expensive.
Actually, I moved on from a G4 service from Relish (70Mbps) to the Hyperoptic FTTP that the building management sensibly allowed them to install (247 Mbps for £20 a month). but BT/Openreach - WTF??
