(Reuters) - FedEx Corp ( FDX ) said on Friday it faced substantial disruptions throughout its networks due to a global IT outage experienced by a third party software vendor.

A global tech outage was disrupting operations in multiple industries on Friday, with airlines halting flights, some broadcasters going off-air and everything from banking to healthcare hit by system problems.

It was not clear if the network disruption reported by FedEx ( FDX ) were related to outages at Microsoft and cybersecurity firm CrowdStrike ( CRWD ).

"Contingency plans have been activated to mitigate impacts but potential delays are possible for package deliveries with a delivery commitment of July 19," FedEx ( FDX ) said.

Peer United Parcel Service ( UPS ) also warned of potential delivery delays and added that contingency plans were in place.

Railroad operator Union Pacific Corp ( UNP ) said the CrowdStrike ( CRWD ) software outage had "varying levels of impact" across its network but added that backup protocols helped it communicate with its teams and dispatchers.
