In an unprecedented event, a recent update to CrowdStrike's endpoint security software has caused a major global outage affecting various Microsoft services, including Windows and Office 365. The update, rolled out on Friday, has resulted in widespread instances of the dreaded 'blue screen of death' (BSOD) on Windows devices, leaving users unable to access their systems. The impact of this outage has been felt across a wide range of sectors, from information technology (IT) companies to airports and banks.

CrowdStrike Error: What Happened
The issue emerged following a CrowdStrike update that led to BSOD on numerous Windows devices. Affected users reported seeing the error message, "Your device ran into a problem and needs to restart," only for their devices to become stuck in a boot loop upon restarting. According to Microsoft, the error is associated with the STOP code “PAGE_FAULT-IN-NONPAGED_AREA,” which logs indicate is due to a failure of a CrowdStrike agent system file.
CrowdStrike Error: Its Impact
Downdetector, a software status monitoring website, highlighted that the outage has significantly impacted several Microsoft services, including Microsoft Store and Microsoft 365. Alarmingly, the issue also disrupted 911 emergency services in several U.S. states. Social media reports suggest that banks, airports, and IT companies around the world have faced severe disruptions due to the CrowdStrike update error.
In Berlin, airport authorities suspended all flights, citing a "technical problem," and cancelled all check-in and flight services until 10 am local time. U.S. airlines, including Delta, United, and American Airlines, also grounded flights, with the Federal Aviation Administration (FAA) attributing the disruptions to a communication issue.
In India, IndiGo Airlines issued a statement acknowledging the impact on its services, leading to long waiting lines and booking errors. The airline attributed the problems to Microsoft Azure and assured that their digital experts are working on a solution. Akasa Air and Indian Airlines issued similar statements.
Media outlets were not spared either, with the UK's Sky News and CBBC, and Australia's ABC News among those affected by the global outage. The London Stock Exchange (LSE) also reported issues, with the LSE Group stating that its RNS news service was unable to publish on the LSE website.
CrowdStrike Error: Response
In response to the outage, both CrowdStrike and Microsoft have issued statements. Microsoft reported that several "mitigation actions" were in progress and that efforts were being made to redirect affected traffic to "healthy systems." The company acknowledged that the issue began at 6 pm ET (3:30 am IST) and primarily affected customers in the Central U.S. region.
A Microsoft spokesperson told Gadgets 360, "We're aware of an issue affecting Windows devices due to an update from a third-party software platform. We anticipate a resolution is forthcoming."
CrowdStrike, in a statement accessible behind a registration wall, acknowledged the issue, stating it "is aware of crash reports." On the CrowdStrike subreddit, a moderator shared a workaround for affected users, advising them to boot into Safe Mode or the Windows Recovery Environment, navigate to the C:\Windows\System32\drivers\CrowdStrike directory, delete the file matching “C-00000291*.sys,” and then boot the system normally.
In a subsequent update, the Texas-based cybersecurity firm revealed that the problem was related to a “Falcon Sensor” on Windows following a content deployment. CrowdStrike confirmed that its engineering teams had patched the issue and reverted the changes.
As both companies continue to work on resolving the fallout from the update, users and businesses worldwide await a fu
ll restoration of services.
