WELLINGTON, New Zealand (news agencies) — A global technology outage grounded flights, knocked banks offline and media outlets off air on Friday in a massive disruption that affected companies and services around the world and highlighted dependence on software from a handful of providers.
Cybersecurity firm CrowdStrike said that the issue believed to be behind the outage was not a security incident or cyberattack.
The issue affected Microsoft 365 apps and services, and escalating disruptions continued hours after the technology company said it was gradually fixing it.
The website DownDectector, which tracks user-reported internet outages, recorded growing outages in services at Visa, ADT security and Amazon, and airlines including American Airlines and Delta.
News outlets in Australia reported that airlines, telecommunications providers and banks, and media broadcasters were disrupted as they lost access to computer systems. Airlines in the U.K., Europe and India reported problems and some New Zealand banks said they were offline.
Microsoft 365 posted on X that the company was “working on rerouting the impacted traffic to alternate systems to alleviate impact in a more expedient fashion” and that they were “observing a positive trend in service availability.”
The company did not respond to a request for comment. It did not explain the cause of the outage further.
CrowdStrike CEO George Kurtz posted on social media platform X that the company “is actively working with customers impacted by a defect found in a single content update for Windows hosts.”
He said: “This is not a security incident or cyberattack. The issue has been identified, isolated and a fix has been deployed.”
New Zealand’s acting prime minister, David Seymour, said on X that officials in the country were “moving at pace to understand the potential impacts” of the global problem.
“I have not currently received any reporting to indicate these issues are related to malicious cyber security activity,” Seymour wrote. The issue was causing “inconvenience” for the public and businesses, he added.
Israel’s Cyber Directorate that it was among the places affected by the global outages, attributing them to a problem with Crowdstrike. The outage also hit the country’s post offices and hospitals, according to the ministries of communication and health.
Meanwhile, major disruptions reported by airlines and airports grew.
In the U.S., the FAA said the airlines United, American, Delta and Allegiant had all been grounded. Travelers at Los Angeles International Airport slept on a jetway floor, using backpacks and other luggage for pillows, due to a delayed United flight to Dulles International Airport early on Friday.
Airlines, railways and television stations in the United Kingdom were being disrupted by the computer issues. The budget airline Ryanair, train operators TransPennine Express and Govia Thameslink Railway, as well as broadcaster Sky News are among those affected.
“We’re currently experiencing disruption across the network due to a global third party IT outage which is out of our control,’’ Ryanair said. “We advise all passengers to arrive at the airport at least three hours before their scheduled departure time.”
Edinburgh Airport said the system outage meant waiting times were longer than usual. London’s Stansted Airport said some airline check-in services were being completed manually, but flights were still operating.
Widespread problems were reported at Australian airports, where lines grew and some passengers were stranded as online check-in services and self-service booths were disabled. Passengers in Melbourne queued for more than an hour to check in, although flights were still operating.
Airline operations in India were disrupted, affecting thousands.
The privately-owned IndiGo airlines told the passengers on X that the Microsoft outage on Friday impacted airline operations in India, inconveniencing thousands of passengers.
