How come that BT sends offers of Full Fibre 900 to people in this postcode? I always thought that only one ISP puts fibre cables in the ground.
Is this overbuilding? Really?
Overbuilding based on business realities. Let us say that you are BT ............. defending their business by overbuilding.
I do understand the business case, but struggle a bit with accepting the waste of resources, including public money that must have gone into delivering FullFibre to these remote towns and even smaller groups of houses. No doubt subsidising is the right thing to do. CDS (https://www.connectingdevonandsomerset.co.uk) has an appalling history and BDUK (Broadband Delivery UK) doesn't seem to know whether they should rename itself once in a while and appoint new chairs etc or actually work on Broadband Delivery. But let's not get too deep into the politics.
If an AltNet (like Jurassic Fibre in this case) builds with substantial investment, and then Openreach throws all their much bigger resources at the same pool of target households (by overbuilding) the AltNet wouldn't stand a chance. I have seen these discussion over and over again, people have never heard the name of "Jurassic Fibre", limited or no trust in the brand, so they book what they know which is BT. This includes being ripped off on price, but let's ignore this for the moment.
As for
Airband, I have seen their marketing teams targeting areas near Axminster/Devon. BIG promises, but once you look at details, you realise that they only resell Openreach's VDSL, not their own FullFibre which is only available in few locations.
Are we sure there is no behind-the-scenes fibre cable sharing, even between arch rivals like OpenReach and Jurassic Fibre? I have seen the Jurassic branded cabling teams working here for many many months, but never similar teams of OpenReach.
