I emailed but didn't hear back, so I sent a Facebook message to their team.
They came back with:
"Hi, thank you for your message.
At the moment your address is within our second phase build which will commence September 2020.
Have you registered interest on our website so we can keep you informed of our progress?"
No concrete dates, just a start date for Exmouth in general I take it.
At a guess I would say it's going to be mid-late 2021 by the time they get to us, fingers crossed for earlier though.
That is odd, I also assumed they were covering all of Exmouth, especially Dinan.
It's got to be more cost effective to lay fibre around there than other parts of Exmoth.
