Chokepoint risk exposure
Why ArangoDB: Graph / network. What share of shipments transit Suez / Panama / Malacca, and the reachability impact of a closure.
Reachability when GIBRALTAR closes
29 → 11 reachable origin→destination pairs
Closing the GIBRALTAR chokepoint cuts network reachability from 29 to 11 pairs — a loss of 18 reachable pairs across 9 origins (open) / 9 origins (closed).
Reroute impact when SUEZ closes (ports/USNYC → ports/CNSHA)
+76.22hadded transit time
Baseline transit 355.97h → reroute transit 432.19h when the shortest path must detour around SUEZ.
Chokepoint criticality ranking
Each chokepoint by share of network lanes transiting it, paired with its betweenness criticality — close GIBRALTAR and reachable pairs drop 29 → 11.
| Chokepoint | Transiting / total lanes | Transit share | Criticality |
|---|---|---|---|
| GIBRALTAR | 16 / 40 | 40.0% | 1.429 |
| PANAMA | 14 / 40 | 35.0% | 1.786 |
| SUEZ | 6 / 40 | 15.0% | 1.071 |
