"I'm not saying it can't happen but there is a lot of resilience in place, on all network types, nowadays."
Is there, really? We're talking about BT here, remember. They're not rolling out IP to improve QoS (in the general sense), they're doing it as part of a plan to make money for the Board and the shareholders. 'Investing', especially in resilience, isn't a concept they understand.
