WELLINGTON, New Zealand (AP) — A widespread Microsoft outage was disrupting flights, banks, media outlets and companies around the world on Friday.

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.”

The company did not respond to a request for comment. It did not explain the cause of the outage further.

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.

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.”

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.

Amsterdam’s Schiphol Airport said on its website that the outage was having a “major impact on flights” to and from the busy European hub. The outage came on one of the busiest days of the year for the airport, at the start of many people’s summer vacations.

In Germany, Berlin Airport said Friday morning that “due to a technical fault, there will be delays in check-in.” It said that flights were suspended until 10 a.m. (0800GMT), without giving details, German news agency dpa reported.

At Rome’s Leonardo da Vinci airport, some US-bound flights had posted delays, while others were unaffected.

Australian outages reported on the site included the banks NAB, Commonwealth and Bendigo, and the airlines Virgin Australia and Qantas, as well as internet and phone providers such as Telstra.

News outlets in Australia — including the ABC and Sky News — were unable to broadcast on their TV and radio channels, and reported sudden shutdowns of Windows-based computers. Some news anchors broadcast live online from dark offices, in front of computers showing “blue screens of death.”

Shoppers were unable to pay at some supermarkets and stores due to payment system outages.

The New Zealand banks ASB and Kiwibank said their services were down.

An X user posted a screenshot of an alert from the company Crowdstrike that said the company was aware of “reports of crashes on Windows hosts” related to its Falcon Sensor platform. The alert was posted on a password-protected Crowdstrike site and could not be verified. Crowdstrike did not respond to a request for comment.
