WiseTech platform CargoWise experienced a 22-hour service delay affecting customs messaging in Great Britain and Japan. Operations returned to normal by the morning of October 29, 2026, after the software provider cleared its message backlog.
Why it matters
For logistics operators relying on automated customs declarations, platform outages can stall cargo transit and disrupt compliance timelines. Managing these interruptions requires clear communication protocols to avoid duplicate data submissions that exacerbate system load.
The system disruption lasted 22 hours from the 10:37 am acknowledgement on October 28 until recovery at 8:33 am the following day. Affected users across British and Japanese markets were explicitly warned against resubmitting pending messages to prevent further queue growth.
The players
WiseTech
An international technology firm that develops the CargoWise software platform for logistics service providers.
CargoWise
A global supply chain software platform used by logistics providers to manage customs and freight documentation.
The details
The outage impacted the automated exchange of customs declarations between CargoWise and local regulatory authorities. To maintain data integrity, WiseTech engineers monitored queue processing while advising clients to withhold resubmission attempts. This strategy prevented the backlog from snowballing as the system attempted to reconcile thousands of pending requests once processing resumed.
Timeline
October 28, 2026, 10:37 am: WiseTech acknowledges the messaging delay.
October 28, 2026, 8:47 pm: WiseTech processes backlogs across most queues.
October 29, 2026, 8:33 am: WiseTech confirms full processing of the messaging backlog.
Market Landscape
This messaging delay represents the second significant service disruption for the CargoWise platform this year. It follows a separate outage involving log-in failures that occurred in June 2026.
Logistics managers should maintain internal logs of communication delays with customs interfaces to substantiate potential transit penalties with clients. When platforms encounter similar backlogs, enforce a 'do not resubmit' policy to prevent system-wide compounding.
The takeaway
Reliant operators should develop manual failover communication protocols when customs gateways go dark. Monitor vendor status pages or internal service alerts for clear directives on whether to queue or halt submissions during future system degradation.
