A sweeping internet disruption on Thursday briefly took out a wide range of major corporate websites — from FedEx and Delta to HSBC and McDonald's. The outages coincided with reports of system disruptions from Akamai and Oracle, two key providers of internet infrastructure services. Oracle said Thursday afternoon that its outage was the result of Akamai's service disruption. "We are monitoring a global issue related to a partner Edge DNS that is impacting access to many internet resources, including Oracle cloud properties," Oracle said. Akamai's Edge DNS service helps route web browsers to their correct destinations and also provides a security service. Among the affected websites were Fidelity, the US Securities and Exchange Commission's document search site, Airbnb, and British Airways. Most of the sites were back up and running in under an hour.<br/>
