It's great.
When I moved to Watford nearly a decade ago, the entire estate/street had no significant broadband.
They offered me "up to 4Mbps". I'm not joking. And wanted me to pay £160 to resurrect the line because obviously previous tenants had not thought it worth the effort. No cable. No alternative providers.
No fibre. That was it. We all used 4G etc. instead and got far better speeds for years.
I could literally have thrown a stone and hit the city centre.
I moved near Oxford. Completely rural area, miles from anything. I got 30Mbps with an option to 70Mbps. Who through? Openreach and their resellers. That's it. No other options. Nothing. Not even a wifi or satellite provider.
I bought a router with DSL and 5G and that's all I can get (and the 5G is actually 4G and very ropey but better than nothing if the DSL goes off).
25+ years ago, when my brother and I first convinced my parents to move away from a modem and get a DSL line (which up until then was just something that we only heard US people talk about on IRC), we got 8Mbps down, then 24Mbps in the space of a couple of years. I've literally not progressed significantly in home DSL connectivity (or wealth of options) in over 25 years.
I would buy a Starlink connection TOMORROW if Elon wasn't involved in it (come on and hurry up with yours, Bezos! At least you're the lesser of two evils!).
So all this "world-leading" nonsense implication is just that. My daughter in Spain has gigabit fiber (proper fibre FTTP, a literal fibre hanging out of the wall) by default. I've priced up leased lines, backup DSL connections, 5G, etc. for workplaces smack-bang in the middle of towns and only leased-lines are at all viable in terms of speeds for them, but cost the Earth.
We are *decades* behind. Literally decades. Some areas get ludicrous speed, but the outliers never catch up, or even match the pace (if it took 10 years to upgrade a dense city, for example, why would it take 25 years for a rural connection to pick up the tech that's now OBSOLETE in the city and still be behind?).
There is still no plan for ANYTHING in my area in terms of upgrades. All the community wifi, etc. projects don't cater to us or require so many people to sign up we'd have to start importing residents to achieve the necessary numbers. The only option is to ignore ALL existing infrastructure and go with something like Starlink. Which tells you just how good "BT" / "Openreach" / "Ofcom" really are.
