A couple of things
If only a certain prime minister hadn't decided she wanted competition from the American cable companies, we might have had a UK-wide FTTH network over 25 years ago.
I was on an Openreach briefing call on Tuesday. I was surprised to hear that FTTC speeds will be reduced down to 2Mb download as they start to migrate voice services to All-IP.
My experience of having FTTP services installed by Openreach in inner London is shambolic - still waiting a year on for one of them to be installed. No idea how they are going to get this done by the end of 2025 to support their All-IP directive.
