Put all your backups in one basket, and then pray that nobody crushes the basket.
That is negligence, practical if not contractual.
Over ten years ago, my employer was spinning up a new DC across the state and had three links between it and the primary DC. Two were pretty direct, but we needed a third because at one point in the 300 mile path, the two main links went within 400 meters of each other.
So how national-security-adjacent critical systems like an airport system doesn't have a larger set of backup links, and validates that they are geographically separate up until the connections, and have realtime alerting on the connection status, is surprising to me.
last time this happened in my area a local farmer was burying a cow and took out the whole towns connection
