Passengers travelling from Nigeria to other parts of the world on Friday were stranded as several foreign airlines delayed and cancelled flights as a result of a global technology outage caused by a faulty software update.

At the heart of the massive disruption is CrowdStrike, a cybersecurity firm that provides software to thousands of companies worldwide.

Delta Airlines, the largest U.S carrier delayed its Lagos-Atlanta flight, pushing the departure time from 12noon to 3pm on Friday.

The affected passengers were accommodated in hotels while some had to return home.

The airline stated that any customers whose flights are impacted will be notified by Delta via the Fly Delta app and text message.
