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
Thank you.
