I think what the week’s activity has shown is that a lot of mission critical systems in business, health care etc have a single point of failure – a single telecomms provider.
I work in aeromedical retrieval and we have a principle of multiple redundant systems for mission critical systems.
eg each aircraft has two engines, two pilots and two wings (last one is a joke).
The learning might be to have different systems as you do Kate.
