It appears the built-in time expiry period in the trust relationships between various organisations and clients will increasing become a weak point in the world in the future. Whether these moving parts are in trust only for three months, three years or more is not the issue, it is the fact that periodic resync and retrust needs to happen, means that it may result in a cascadable failure of our infrastructure in the future. Say if a nuclear disaster / earthquake take down one city, will it lead to paralysis of servers and services across the world? Perhaps it is time to start auditing the Internet and identify the weak points.

That doesn’t feel like a weak point to me. In the case you described, trust likely is broken. As a user, I may not care and instruct my browser to ignore the fact that the certificate is broken because I understand the likely cause.
