Airlines worldwide began to recover on Saturday after a massive IT crash disrupted global carriers, banks, and financial institutions. The chaos, one of the most significant IT failures in recent years, was triggered by an update to an antivirus program.
On Friday, airports were overwhelmed with passengers as dozens of flights were canceled due to the crash of systems operating on Microsoft Windows. The disruption led to long waits and operational struggles.
By Saturday afternoon, multiple US airlines and airports across Asia had resumed operations. Check-in services were restored in Hong Kong, South Korea, Thailand, and largely back to normal in India, Indonesia, and at Singapore’s Changi Airport.
“The check-in systems have come back to normal (at Thailand’s five major airports). There are no long queues at the airports as we experienced yesterday,” said Airports of Thailand president Keerati Kitmanawat at Bangkok’s Don Mueang airport.
Microsoft reported the issue began at 1900 GMT on Thursday, affecting Windows users running CrowdStrike Falcon cybersecurity software. CrowdStrike rolled out a fix, with CEO George Kurtz apologizing to those impacted.
The White House stated that US President Joe Biden’s team was in communication with CrowdStrike and affected entities, offering assistance. “Our understanding is that flight operations have resumed across the country, although some congestion remains,” a senior US administration official said.
Reports indicated that health services in the Netherlands and Britain might have been affected, suggesting the full impact was not yet known. Media companies like Britain’s Sky News and Australia’s ABC also reported disruptions.
By Saturday, services in Australia had mostly normalized, although Sydney Airport still experienced delays. Authorities warned of an increase in scam and phishing attempts following the outage.
Banks in Kenya and Ukraine reported digital service issues, and customer services for various companies were disrupted.
“The scale of this outage is unprecedented, and will no doubt go down in history,” said Junade Ali of Britain’s Institution of Engineering and Technology, noting the last incident of this magnitude was in 2017.
Airline staff at some airports resorted to manual check-ins, causing long lines and frustration among travelers. The US Federal Aviation Administration initially grounded all flights but later allowed airlines to re-establish services and clear backlogs.
India’s largest airline, Indigo, announced that its operations had been “resolved” in a statement on X. “While the outage has been resolved and our systems are back online, we are diligently working to resume normal operations, and we expect this process to extend into the weekend,” the carrier said Saturday.
A passenger at Delhi Airport reported the situation returning to normal by midnight Saturday, with only slight delays in international flights. Low-cost carrier AirAsia continued to work on recovering its departure control systems, advising passengers to arrive early and be prepared for manual check-in.
Chinese state media reported that Beijing’s airports were unaffected. In Europe, major airports, including Berlin, resumed departures and arrivals after suspending flights on Friday.
Companies scrambled to patch their systems and assess the damage. Officials ruled out foul play to mitigate panic. CrowdStrike’s Kurtz stated that his teams were “fully mobilized” to assist affected customers and that a fix had been deployed.
However, experts like Oli Buckley of Britain’s Loughborough University questioned the practicality of implementing the workaround. “While experienced users can implement the workaround, expecting millions to do so is impractical,” he said.
The incident has prompted a reevaluation of society’s reliance on a few tech companies for critical services, urging a reconsideration of dependencies on such technology.
