CrowdStrike failure: What you need to know

To provide scope for this, more than 3,000 flights within, into, or out of the US were canceled on July 19, with more than 11,000 delayed. Planes continued to be grounded in the days since, with nearly 2,500 flights canceled within, into, or out of the US, and more than 38,000 delayed, three days after the outage occurred.

The outage also significantly impacted the healthcare industry, with some healthcare systems and hospitals postponing all or most procedures and clinicians resorting to pen and paper, unable to access EHRs.

Given the nature of the fix for many enterprises, and the popularity of CrowdStrike’s software, IT organizations have been working around the clock to restore their systems, with many still mired in doing so days after the initial faulty update was served up by CrowdStrike.
