Yes, these are pictures of a nuclear bunker, this being the forthcoming Bogons data centre near Comrie. It is also where our fibre should meet that of the wider world and will, we hope, achieve economies of scale from aggregation with other users that will make our network ever cheaper to run: if we just bought our backhaul (the link between the glen and the wider internet) at about the same initial cost from a commercial provider, we’d still have to pay Openreach’s Excess Construction Costs to get the link from the Strathyre Exchange to the entrance to the glen, but we’d never thereafter gain any benefit from others using the wider link. With the bunker, the idea is that we start at par and then go down in cost from there.
We’ve had the cabling company that works with Bogons, our preferred supplier, out to look at the glen and they’ve now been commissioned to come back and carry out the necessary detailed survey (taking 4/5 days) to fully cost what’s needed. That’s happening from 8 March. We’ve asked them to provide us with a menu of costs for each part of the network: the 13km that gets to all bar 22 of the 178 properties in our area and for each segment beyond that (totalling another 13km). This will let us work out just how much of the work we need to do ourselves to get to all parts of the glen: we know that the only way we will be able to provide fibre to every house or business in the area will through significant community effort as part of the lay.
The rest of our costs are now fairly firm, so we’re awaiting the survey results that will let us know just where we stand. We’re including in that survey the costs of crossing both the glen road where needed and the A84 where we’re serving Balquhidder Station.
Like many other rural Scottish communities, our problem is geography: having a fairly small but highly dispersed population strung out along the loch sides and side glens. Our core funding from Community Broadband Scotland will cover the capital expenditure and setup for our external connection and at least the bulk of our costs for our backbone within the glen, which is great. However, connecting the outlying clusters of properties (most of them farms) might be pushing the limits of available funding.
