All airports in Spain were also experiencing “disruptions” from an IT outage that has hit several companies worldwide on Friday, the airport operator Aena said. Lisbon airport, Portugal’s biggest, also experienced disruptions amid a global cyber outage.
Hong Kong’s airport also said some airlines had been affected, with its authority issuing a statement in which it linked the disruption to a Microsoft outage.
Singapore’s airport said Friday that some airlines had been affected by an IT outage, as widespread technical problems were reported by flight operators around the world.
“Due to a global outage affecting IT systems of many organisations, the check-in process for some airlines at Changi Airport is being managed manually,” the airport said in a Facebook post.
Swiss International Air Lines said on Friday that its systems had not been impacted by a global IT outage but Swiss flight operations have been affected due to disruptions at partner companies and air traffic control.
Prague Airport also reported some delays to departures on Friday morning due to an outage of the global check-in system used by a large number of airlines, but said on X social media platform the situation had stabilised by midday.
Malaysia’s airport operator also Friday that some airlines had been affected by an IT outage, as widespread technical problems were reported by airlines around the world.
“Our network of airports in Malaysia remains unaffected by the global Microsoft outage. However, some of our airline partners are experiencing disruptions due to this issue,” Malaysia Airports Holdings Berhad said in a statement.

“Flights are currently arriving and departing however there may be some delays throughout the evening,” a Sydney Airport spokesman said.
“We have activated our contingency plans with our airline partners and deployed additional staff to our terminals to assist passengers.”
Australia’s National Cyber Security Coordinator said the “large-scale technical outage” was caused by an issue with a “third-party software platform”, adding there was no information as yet to suggest hacker involvement.
Sky News in the UK said the glitch had ended its morning news broadcasts, while Australian broadcaster ABC similarly reported a major “outage”.
Some self-checkout terminals at one of Australia’s largest supermarket chains were rendered useless, displaying blue error messages.
New Zealand media said banks and computer systems inside the country’s parliament were reporting issues.
Australian telecommunications firm Telstra suggested the outages were caused by “global issues” plaguing software provided by Microsoft and cybersecurity company CrowdStrike.
Microsoft said in a statement it was taking “mitigation actions” in response to service issues.
It was not clear if those were linked to the global outages.
“Our services are still seeing continuous improvements while we continue to take mitigation actions,” Microsoft said in a post on social media platform X.
CrowdStrike could not immediately be reached for comment.
University of Melbourne expert Toby Murray said there were indications the problem was linked to a security tool called Crowdstrike Falcon.
“CrowdStrike is a global cyber security and threat intelligence company,” Murray said.
“Falcon is what is known as an endpoint detection and response platform, which monitors the computers that it is installed on to detect intrusions (i.e. hacks) and respond to them.”
University of South Australia cybersecurity researcher Jill Slay said the global impact of the outages was likely to be “enormous”.
