Accenture subsidiary Navitaire has blamed a blackout at a "third party data centre in Sydney" for a failure of airline check-in systems used by Virgin Australia and Jetstar on Saturday.
"A power failure occurred in a third party data centre in Sydney which impacted the Navitaire reservation systems," an Accenture Australia spokeswoman told iTnews.
Weekend air travellers faced delays at major Australian airports after the check-in systems for Virgin Australia and Jetstar crashed.
Tiger Airlines was also thought to be affected by the problem, but not Qantas.
Virgin Australia confirmed its check-in system, operated by Navitaire, experienced a nationwide outage affecting all ports.
Manual check-ins were performed during the Navitaire outage.
Travellers took to the microblogging service Twitter over the delays and "chaos".
