take a trip to Littlehampton.
Over 40 years ago, Openreach installed all cables underground.
They should have been one of the first places for FTTP, if all the underground chambers had not collapsed 
Every time Openreach go to add further FTTP there the funding is used up almost immediately in repairing the underground chambers.
Yep, underground is really inefficient, I see a lot round here, 6 hours digging, 30 mins works, 3 hours reverse digging to put everything back how it was. So an entire day for a 30 min repair. Noisy as hell, a pole instead? Yes please.
Not just collapsed ducts either, but all the accidents from diggers cutting the cables.
Never seen a pole blown down before, for most of the country it will be a non issue.
