Widespread technology outage disrupts flights, banks, media outlets and companies around the world

At Hong Kong’s airport, Yvonne Lee, 24, said she only found out her flight to Phuket in Thailand was postponed to Saturday when she arrived at the airport, saying the way it was handled would “affect the image of Hong Kong’s airport very much.”

Her already short five-day trip would now have to be further shortened, she said.

Some athletes and spectators descending on Paris ahead of the Olympics were delayed as was the arrival of their uniforms and accreditations, but Games organizers said disruptions were limited and didn’t affect ticketing or the torch relay.

Toronto Pearson International Airport and Montréal–Trudeau International Airport both said the outage could lead to flight delays and cancellations.

Meanwhile, Air Canada said there is no major impact to its operations, adding it is monitoring the situation closely.

University Health Network, one of Canada’s largest hospital networks, said some of its systems had been impacted by the outage. In a post to social media, it said clinical activity was continuing as scheduled, but some patients may experience delays.

A disturbing reminder of vulnerability

“This is a very, very uncomfortable illustration of the fragility of the world’s core internet infrastructure,” said Ciaran Martin, a professor at Oxford University’s Blavatnik School of Government and former Head of Britain’s National Cyber Security Centre.

DownDectector, which tracks user-reported disruptions to internet services, recorded that airlines, payment platforms and online shopping websites across the world were affected — although the disruption appeared piecemeal and was apparently related to whether the companies used Microsoft cloud-based services.

Cyber expert James Bore said real harm would be caused by the outage because systems we’ve come to rely on at critical times are not going to be available. Hospitals, for example, will struggle to sort out appointments and those who need care may not get it.

“There are going to be deaths because of this. It’s inevitable,’’ Bore said. “We’ve got so many systems tied up with this.”

Microsoft 365 posted on social media platform X that the company was “working on rerouting the impacted traffic to alternate systems to alleviate impact” and that they were “observing a positive trend in service availability.”

CrowdStrike said in an emailed statement that the company “is actively working with customers impacted by a defect found in a single content update for Windows hosts.”

It said: “This is not a security incident or cyberattack. The issue has been identified, isolated and a fix has been deployed.”

Meanwhile, governments, officials and companies across the world scrambled to respond.

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,” adding that he had no information indicating it was a cybersecurity threat.

The issue was causing “inconvenience” for the public and businesses, he added.

On the Milan stock exchange, the FTSE MIB index of blue-chip Italian stocks could not be compiled for an hour, though trading continued.

Major delays reported at airports grew on Friday morning, with most attributing the problems in booking systems of individual airlines.

In the U.S., the FAA said the airlines United, American, Delta and Allegiant had all been grounded.

Airlines and railways in the U.K. were also affected, with longer than usual waiting times.

While the outages were being experienced worldwide, Australia appeared to be severely affected by the issue. Disruption reported on the site DownDetector included the banks NAB, Commonwealth and Bendigo, and the airlines Virgin Australia and Qantas, as well as internet and phone providers such as Telstra.

National news outlets — including public broadcaster ABC and Sky News Australia — were unable to broadcast on their TV and radio channels for hours. Some news anchors went on air online from dark offices, in front of computers showing “blue screens of death.”

Hospitals in several countries also reported problems.

Britain’s National Health Service said the outage caused problems at most doctors’ offices across England. NHS England said in a statement said the glitch was affecting the appointment and patient record system used across the public health system.

Some hospitals in northern Germany canceled all elective surgery scheduled for Friday, but emergency care was unaffected.

Israel said its hospitals and post office operations were disrupted.

In South Africa, at least one major bank said it was experiencing nationwide service disruptions as customers reported they were unable to make payments using their bank cards in stores. The New Zealand banks ASB and Kiwibank said their services were down as well.

Shipping was disrupted too: A major container hub in the Baltic port of Gdansk, Poland, the Baltic Hub, said it was battling problems resulting from the global system outage.
