LOS ANGELES -FedEx Corp on Wednesday said its U.S. Express deliveries could be delayed due to an overnight Federal Aviation Administration (FAA) information technology system outage that the regulatory agency said has been resolved.

FedEx's signature Express service uses planes to provide overnight deliveries. The company said shipments delayed due to the outage are not eligible for a refund or credit.

"Potential delays are possible for package deliveries across the U.S. with a delivery commitment of October 25, 2023," FedEx said in a service alert.

In an email to Reuters, FedEx said the IT outage at its Memphis, Tennessee, air hub was an "FAA issue."

FAA told Reuters that departures were stopped briefly on Tuesday night due to an equipment issue that occurred during a scheduled software update. It added that operations in Memphis-area air traffic facilities have returned to normal.

FedEx competitor United Parcel Service (UPS), whose air hub is located in Louisville, Kentucky, told Reuters that its flights "have been operating as expected with nothing to report regarding delays."
