Widespread Impact

Reports indicate that the outage has disrupted services globally, with significant effects in the UK where broadcaster Sky News went off air. The outage also impacted users of Microsoft's Azure and Office 365 services. Microsoft acknowledged the issue in a post on X, stating, "We are investigating an issue impacting users' ability to access various Microsoft 365 apps and services." The company noted that users might see gradual relief as they work to resolve the problem.


Airline Disruptions

Airlines have been hit hard by the outage. In Australia, Qantas grounded flights, while in the US, low-cost carriers Frontier and Sun Country Airlines faced similar issues. In Europe, Ryanair users reported difficulties accessing the airline's app and website, with the company confirming a "global 3rd party IT outage" on social media. Several European airports, including Berlin Brandenburg and Edinburgh, reported IT issues affecting check-in and departure boards. Airports in Amsterdam, New Zealand, Japan, and India also experienced disruptions.



Cause of the Outage

Initial reports suggest that the global IT outage was caused by a problematic antivirus software update from security firm Crowdstrike. The update reportedly led to devices becoming "bricked," rendering them inoperable due to corrupted software. On Reddit, users of the Crowdstrike subreddit shared what appeared to be an advisory from the company, indicating that the Falcon Sensor might be the cause. The advisory noted, "CrowdStrike is aware of reports of crashes on Windows hosts related to the Falcon Sensor. Symptoms include hosts experiencing a bugcheck\blue screen error related to the Falcon Sensor."


Moving Forward

As companies and service providers work to mitigate the issues, the global community continues to experience the fallout from this unprecedented IT outage. With significant disruptions in banking, media, and travel, the need for robust IT infrastructure and rapid response protocols has never been more evident. The situation serves as a stark reminder of the interconnectedness of modern services and the potential for widespread impact when technology fails.
