CrowdStrike Holdings Inc. Chief Executive Officer George Kurtz said in a Thursday LinkedIn post that more than 97% of the company’s Falcon agent sensors that use Windows are now back online.

CrowdStrike sent out a botched software update that crashed millions of computers on July 19, triggering a global IT outage that grounded flights, closed businesses and brought markets to a standstill. The disruption lasted days, wreaking approximately US$5.4bil (RM25.1bil) of havoc on Fortune 500 companies, according to Parametrix. CrowdStrike shares have fallen by about a quarter since the outage.
