Re: For those wondering
If the average speed for the UK is 5mbps,
It isn't, and hasn't been for many years, quite possibly not for a decade. Estimates vary but even the most pessimistic put us well into double digits now. Ofcom's latest figure (2017) is 36Mb/s.
I'm actually a little surprised that it's that high given that so many people only opt for the lowest spec package but Ofcom are using Samknows data so it's probably not far out.
