A widespread 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.

In South Africa, at least two major banks said they experienced service disruptions as customers complained they weren’t able to make payments using their bank cards at grocery stores and gas stations or use ATMs.

Both banks said they were able to restore services hours later.

Southern African regional airline Airlink also reported that its IT network and telephone lines were down because of what it called a global network outage, but said flights were not affected.

A look at some of the disruptions affecting airlines and airports around the world:

Germany: Eurowings says it had to cancel German domestic flights as well as services to and from the U.K. on Friday. The budget subsidiary of Lufthansa said that its check-in and boarding processes were impaired by the computer disruption. The airline called on people traveling inside Germany to book a train ticket and submit it for reimbursement.

South Korea: Several low-cost airlines reported problems, triggering delays in passenger boardings at Incheon international Airport, the country’s biggest airport. Jeju Air Co. said it was experiencing problems with ticketing and other services on its website. Air Premia Inc. said key services on its website, such as ticket bookings, cancellations and online check-ins, were not working. The website of Eastar Jet Co. wasn’t accessible as of early Friday evening.

U.S.: United Airlines said the outage was impacting its computer systems and warned customers of potential flight delays. The carrier said some flights are resuming and it is issuing waivers to make it easier to change travel plans within its website.

The London Stock Exchange says it is experiencing disruptions from the technology outage that has created chaos around the globe.

The LSE says its regulatory news service was not working Friday morning but the outage had not affected trading.

“We are currently experiencing a third party technical issue which is impacting some of our services,” a London Stock Exchange Group spokesperson said in a statement.

The exchange says it’s trying to resolve the problem as soon as possible.

Nasdaq said Friday: “Our European markets and U.S. pre-market are operating normally. We expect our U.S. markets to open normally.”

The automated border control system at Bangkok’s two airports have been affected by the tech outage, according to
Kerati Kijmanawat, president of Thailand’s airport authorities.

The ground operation of several airlines at six major Thai airports has also been disrupted, he added. He encouraged passengers to come to the airports at least 4 hours before their departure time.

Airports in Singapore and Malaysia were also reporting similar issues, with long queues and passengers worried about missing their flights due to the long check-in process.

Singapore Post also reported technical disruptions to its services, as did Malaysia’s railway company KTM.

Flights at Germany’s Berlin Airport were delayed on Friday morning as a widespread fault with some Microsoft technology caused chaos around the globe.

At Hong Kong’s airport, hundreds of travellers were queuing for manual check-in around the counters of budget airline HK Express, which said that its global e-commerce system was affected by Microsoft’s service outage.

Hospital clerk Timmy Lo, 29, said that he and his girlfriend had been in the queue for more than two hours waiting to check in for their flight. The delay meant they could only arrive at their hotel in Tokyo in the early hours of Saturday amid infrequent public transportation services.

“I am very tired because I have to stand in line all the time, and we don’t know when we can get in,” he said.

A cyber security expert said internet outages will cause real harm as hospitals and other essential services are disrupted.

“There are going to be deaths because of this. It’s inevitable,’’ said James Bore, the managing director of cyber security consulting company Bores.

“We’ve got so many systems tied up with this. We’ve got emergency services. There are going to be excess deaths. People will die who wouldn’t have otherwise. And we’re not talking millions, but it is going to hurt people. And there are really serious consequences. That’s without getting into anything financial, which is of less importance. This is going to cause harm.”

Some Olympic delegations’ arrivals have been delayed because of the outage, as well as delivery of uniforms and accreditations, Paris Olympics organizers said in a statement.

It has not affected ticketing or the torch relay. ''Our teams have been fully mobilized to ensure the continuity of operations at optimum levels,’' it said.

CrowdStrike CEO George Kurtz said the company was working to fix problems created for Windows users of its tools by a recent update in a post on the social media platform X.

Britain’s National Health Service says a global internet outage is causing problems at most doctors’ offices across England.

NHS England said in a statement said the glitch was hitting the appointment and patient record system used across the public health system. The state-funded NHS treats the vast majority of people in the U.K.

The NHS said the issue was affecting the majority of family doctors’ practices, but was not the 999 number used to call for ambulances in emergencies.

Baltic Hub, a major container hub in the Baltic port of Gdansk, Poland, says it is battling problems resulting from the global system outage.

The hub’s entry gates were temporarily closed on Friday morning and they suspended business.

With athletes and spectators arriving from around the world for the Paris Olympics, the Paris airport authority said its computer systems “are not impacted” by the global outage, but several airlines and airports elsewhere are.

As a result, “this situation has an impact on the operations of airlines at Paris-Charles de Gaulle and Paris-Orly airports: delays in check-in, delays and temporary suspension of some flights. Our teams are mobilized to orient and assist passengers,” the airport authority said in a statement Friday.

The U.K. television station Sky News began broadcasting again after the outage knocked it off the air during the morning.

The news anchor referred to printed notes after getting back on the air.

Sky News was able to deliver news on its app and website during the broadcast outage.

One possible cause of the internet issues plaguing airlines, companies and governments around the world is a tool developed by the online security firm CrowdStrike.

Israel’s Cyber Directorate was among the groups attributing the issues to CrowdStrike.

A recording playing on CrowdStrike’s customer service line said, “CrowdStrike is aware of the reports of crashes on Microsoft ports related to the Falcon sensor,” it said, referring to one of its products used to block online attacks. It said callers should monitor its customer support portal.

Escalating disruptions continued hours after the technology company said it was gradually fixing an issue affecting access to Microsoft 365 apps and services.

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. Some New Zealand banks said they were also 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.”
