So the village was difficult and expensive to lay a fibre to. Someone wanted to make a point and decided to opt for a radio link. Still not a particularly cheap option so they didn't spec it particularly well. Link is not doing what it should.
Sounds to me like someone tried to stretch the money too far. Would be interesting to know where that decision came from. I'm envisaging a situation where a bunch of mid-level managers sat around a table and picked that village as some kind of 'poster child' showing how too little money could be stretched to do the job.
