On Friday, Microsoft users worldwide faced significant disruptions, with major services such as Microsoft 365 encountering widespread outages. This problem quickly extended beyond Microsoft's own applications, affecting various sectors including banking, airlines, and security services.

Speaking with Nanda Kishore, a cybersecurity researcher, Mathrubhumi English gained insight into the nature and scope of the outage. Kishore explained that the impact is specifically related to companies using Cloudstrike’s Falcon Sensor endpoint protection. "The outage affects computers running the Falcon Sensor due to a conflict with Microsoft’s agent. So, those computers using the Falcon sensors are affected by this," Kishore noted. "It is not a Microsoft-created issue but rather one stemming from Cloudstrike. The conflict has led to BIOS errors, which is why it’s misleading to label this as a Microsoft outage."

Why Aren’t All Microsoft Systems Affected?

The question on many minds is why not every system using Microsoft services has been impacted. Kishore clarified, "The outage does not affect all Microsoft systems. It is specifically the systems with Cloudstrike’s Falcon Sensor that are experiencing issues. Systems without this particular security software remain unaffected."

How Long Will It Take to Fix the Issue?

Regarding the resolution, Kishore shared that a temporary solution has been provided, which involves starting systems in safe mode and following a series of troubleshooting steps. "While there is a temporary workaround, the primary challenge lies in developing a permanent fix. They need to release a software update to manage the issue," he said.

The outage has led to widespread disruptions across various industries. DownDetector, a service that tracks internet outages, reported growing problems at major services including Visa, ADT Security, and Amazon. Airlines like American Airlines, Delta, SpiceJet, and IndiGo have also been affected, with disruptions in flight operations at Bengaluru International Airport.

As the situation evolves, both Microsoft and affected organizations are working to resolve the issues and minimize the impact on users worldwide.
