CrowdStrike said that as of Thursday, more than 97% of the systems affected by the IT outage were back online. The incident comes nearly a week after a global IT outage severely affected global businesses, government agencies and air travel. CrowdStrike CEO George Kurtz said the company still has more work to do to repair the impact of last Friday's network outage. In an incident report earlier this week, CrowdStrike said that a vulnerability in the company's quality control tool used to check system update errors caused a serious defect to be pushed to millions of machines running Windows. About 8.5 million devices were affected by the outage, many of which were part of broader enterprise IT systems, meaning that the scope of impact was wider. (Jinshi)
