We have one path that our communication goes which is from Alert over the spine of Ellesmere Island, which is covered in glaciers. It's a beautiful country, but it's very rugged, and glaciers also move. We have the one path. We have multiple means of communication down that path through these towers, mountain top to mountain top, until we get to Eureka, and it goes to the sky to more than one satellite. We have redundant communications but it's only on one path. As a signaller by trade, having a diversity of paths gives you redundancy and flexibility beyond just the fact that you have more than one system going down the same route, but that's quite expensive. Building towers across the top of Alert off Ellesmere Island is not a trivial exercise, and maintaining them is a big deal as well. Where else would you go off Alert because it's very far north?
In a perfect, resourced, unconstrained environment I would agitate for a separate physical path as well, but we've got redundant paths.
