I can only provide theory, not facts, but the city spans half the planet. It's in the Deep Core and it's one of the busiest hubs of space traffic in the galaxy. 310,000,000,000 people populate Cinnagar.
The amount of scanning equipment that the traffic towers across the city would require is clearly of a very, very high volume. Then we have the technicians per tower to wonder about. It's clearly an insane number of staff.
Importantly, Exar Kun has years of 'extreme', 'enormous' growth to undergo, making this a seriously pre-prime feat.
