CrowdStrike IT Outage Not a 'Cybersecurity Incident,' CEO Claims

Microsoft, which allows CrowdStrike to provide antivirus services to Windows computers, earlier reported that the outage also affected its Azure cloud services and Microsoft 365 suite of apps.

CrowdStrike IT Outage Halts Digital Operations

With most of their computers effectively unusable, many businesses had to resort to pen-and-paper to continue some operations, while most had to either delay or cancel schedules due to the outage.

Australia, in particular, has been heavily impacted by the outage as most of its businesses use Windows computers or the CrowdStrike software for their IT networks.

Similar problems are reported across France, which is hosting the Summer Olympics this year, and the UK.

Several Asian countries also confirmed service disruption, although most government units claimed not to have been affected.

Due to the scale of the outage, experts expect that several companies may soon want to hold Microsoft and CrowdStrike financially liable, similar to the response to the cyberattack on car retailers in North America last month.
