In terms of connectivity, I would say no, not with our model.
We have dedicated links to some of our suppliers exactly because we expect greater reliability and availability. These are some of the aspects of fibre optics my colleagues are discussing.
We use protocols with different service providers in Canada and the United States with dedicated MPLS links. This is not necessary for others. We should not forget that there are levels of criticality associated with our systems: there are the “critical”, “standard” and “average” levels. We put in place the measures required to ensure availability.
