TNT says most services are back to normal and it is working hard to clear any backlogs following its IT systems being hit by a virus.

Operations and communications were disrupted when a ransomware attack swept the globe, affecting numerous companies, though TNT says no data breach occurred as far as it is aware and operations of other FedEx companies are unaffected.

The company says: “TNT continues to make significant progress in resuming full services and bringing critical systems back online. These remediation efforts are being carried out methodically to ensure the integrity of TNT’s information systems and operations.”

TNT says contingency plans making use of FedEx Express and TNT networks will remain in place to minimise the impact to customers though warns some customers may continue to experience delays in service and access to package information.

TNT also says: “We cannot measure the financial impact of this service disruption at this time, but it could be material.”
