According to reports, US software giant Microsoft has deployed hundreds of engineers and experts with its customers to restore their services after an outage caused by its cyber security partner CrowdStrike.

According to Microsoft, 8.5 million devices across the world were impacted by the outage caused by an update from CrowdStrike on July 18.

"Deploying hundreds of Microsoft engineers and experts to work directly with customers to restore services," Microsoft says.

The global outage affected several dealerships and even led to the suspension of airline service in India.

The outage caused major disruption to airport and airline operations, with airlines issuing advisories to passengers; IndiGo, SpiceJet, and Akasa were forced to switch to manual mode after online check-in and boarding was disrupted on their networks.

Several users reported the failure on the failure-tracking site Downdetector, and many users took to X (now Twitter) to complain about the “Blue Screen of Death” error message.

Microsoft is working with other cloud providers and stakeholders, including Google Cloud Platform (GCP) and Amazon Web Services (AWS), to share awareness of the state of impact being seen across the industry and in ongoing dialogue with CrowdStrike and its customers. He stated that this is helpful.

The company recognizes the disruption this problem has caused for businesses and in the daily routines of many individuals. Our focus is providing customers with technical guidance and support to safely bring disrupted systems back online.

"It's also a reminder of how important it is for all of us across the tech ecosystem to prioritize operating with safe deployment and disaster recovery using the mechanisms that exist," Microsoft says.
