If you’ve got a router as a Single Point of Failure in a nation spanning critical system, you’re doing it wrong. If you don’t have a rollback plan that can be executed quickly, you’re doing it wrong.

The contractor may have been incompetent, or the router hardware might have been faulty, or the entire plan may have been wrong, but none of that should have taken down the whole system.

Friday may have been the fault of a single router installed by government contractor L3Harris, government officials said Saturday.

That isnt L3Harris’s fault, its the FAA’s fault for letting a single router be the lynchpin of the entire aviation sector.

Who doesn’t use blue-green or canary deployments for something so critical?
