Global shipping was disrupted this week after a cyber incident knocked out scheduling systems at a major port operator.
The company said some terminals lost access to their logistics software, forcing staff to manage ship movements by hand. Port authorities stressed that safety systems were not affected, but the slowdown caused congestion and knock-on delays across several routes.
Details about the incident remain limited. Industry sources say the disruption exposed weaknesses in how heavily ports now rely on automated systems.
The operator said work to restore services is ongoing and that an internal review has been launched.
