Sometimes a tl;dr really helps.

If I understand the article:

  • a flight plan is a series of waypoints.

  • Waypoints are represented using identifiers that are known to not be globally unique.

  • an algorithm attempts to extract the portion of the flight in the UK airspace failed due to one of the non-unique waypoints in a flight plan

  • the failure caused the primary system to halt

  • the backup system takes over, processes the same flight plan and fails the same way, halting as well

  • UK air traffic control can no longer accept/process flight plans, preventing flights from happening

  • it took a while to resolve the system error, and longer to resolve the impacted people
