THE operations of at least two local airlines were affected by the massive IT outage on Friday that caused chaos at airports, banks and businesses across the globe.

Cebu Pacific reported it experienced technical problems from its provider, CrowdStrike, forcing the airline to "handle affected processes manually, potentially causing delays."

AirAsia said its provider, Navitaire, also experienced operational problems.

"This outage is causing unexpected rebooting of machines, leading to some operational disruptions related to check-in processes, self-check-in kiosks, and navigating the AirAsia MOVE app," it said.

AirAsia spokesman Steve Dailisan said on a Facebook post that the airline's top priority "is to minimize any impact on our guests and ensure that all systems are restored to full functionality as soon as possible."

The Manila International Airport Authority (MIAA) said it added personnel to manage queues at check-in counters in the Ninoy Aquino International Airport.

The MIAA said it also gave special kits to affected passengers.

Passengers affected by the system downtime were advised to contact their airlines.

Microsoft said in a technical update on its website that the problems began late Thursday, affecting users of its Azure cloud platform running cybersecurity software CrowdStrike Falcon.

The Department of Information and Communications Technology (DICT) said its Cybersecurity Bureau and the National Computer Emergency Response Team were monitoring the software outage.

"We assure the public that the department does not use the same cybersecurity service provider and that no DICT systems or assets have been affected," DICT spokesman Renato Paraiso said.
