A global tech outage that appeared to be related to issues at global cybersecurity firm CrowdStrike and Microsoft was affecting operations in various sectors on Friday including airports, airlines, media and banks.
Numerous airports and airlines reported IT system issues, resulting in grounded flights and service interruptions.
Notably, Sydney airport has seen flights halted, United Airlines has ceased operations, and the London Stock Exchange Group’s platform has encountered disruptions.
In Germany, Berlin airport experienced IT problems, causing delays in check-ins due to technical faults.
Also, rail transportation has not been spared, as the UK’s Govia Thameslink Railway reported widespread IT issues across its network, leading to potential cancellations and delays.
The company is actively investigating the root cause and has urged passengers to check their journeys before traveling.
Australia’s Telstra Group also reported service disruptions.
Meanwhile, in a post on X, CrowdStrike CEO George Kurtz said the outage was not a “security incident or cyberattack.”
He said it was connected to a “defect found in a single content update for Windows hosts.” He said the issue has been “identified, isolated and a fix has been deployed.”
Also, Microsoft said in a statement on X that “the underlying cause has been fixed,” however, residual impacts continue to affect “some Microsoft 365 apps and services. We’re conducting additional mitigations to provide relief.”
The affected services include PowerBI, Microsoft Teams, and OneDrive for Business, among others. The tech giant is working on mitigation efforts and has already restored some services.
However, this global IT outage highlights the interconnected nature of modern digital infrastructures and the widespread impact that technical disruptions can have across various industries.
