Three days of your visibility events are unrecoverable and freight is still moving. How do you re-establish where everything is?

Answer

Short answer

Rebuild rather than reconstruct: most of those events still exist in carrier systems, EDI mailboxes and handheld queues, so re-ingest them idempotently by date range, then close the residual gap with physical observation at yards and terminals.

Track and trace matters here because the three days of visibility events are answer has to show the boundary, not just the happy path.

Likely follow-ups

  • Which of your carriers can serve a date-range replay, and what do you do about the ones that cannot?
  • A re-ingested event arrives after a later event you already applied. What does your projection do?
  • How would you prove afterwards which parts of the rebuilt history were observed and which were inferred?
  • What would you archive today, cheaply, so that this recovery is a day rather than a fortnight?
