What happened

A defective CrowdStrike Falcon content update caused Windows computers worldwide to crash and enter repeated blue-screen boot failures. Critical services across several sectors were disrupted, and some energy traders and brokers reported severe problems, including inaccessible deal-entry systems. However, contemporary commodity-market reporting found that major oil and gas producers, power suppliers, shipping operations and physical energy supplies in Europe, Africa and the Middle East were largely unaffected; Vitol said some IT systems were affected while core trading continued. CrowdStrike identified the event as a content-validation failure and CISA emphasized that it was not malicious cyber activity. This record therefore documents systemic energy-market and software-supply-chain exposure without claiming a grid-dispatch failure or energy-production outage that the reviewed evidence does not support.

When cited sources give different casualty, damage or spill figures for this event, they’re reported side by side above rather than merged into one number. See how confidence levels work.
