Congestion figures are only useful if you can see how they moved. Most freight sites publish a single live number and overwrite it, which makes historical comparison impossible. Carrgo keeps every weekly edition at its own permanent URL so analysts, journalists and other freight businesses can cite conditions as they stood on a specific date, and so importers can see whether a port is on a genuine recovery or just having a good week.
