 For further comment, the outage, which also took down the London Stock Exchange, has been linked to a faulty update from cybersecurity company CrowdStrike. The company handles the security of many Windows PCs and services around the world. In a statement this morning, CrowdStrike said the issue had been identified, isolated, and a fix has been deployed. The last time there was an internet outage this widespread was when a service called Fastly went down in 2021.
