Tuesday’s disruption of numerous popular websites using the services of US cloud computing firm Fastly has been traced to a software bug, which sneaked into a recent update and got triggered by a user.
The websites of multiple news outlets, the British government, and services like Amazon and Spotify were among those affected by the hour-long outage on Tuesday. Fastly, whose servers were the source of the problem, says it traced the issue to a specific software bug, which its quality control engineers had failed to identify and fix ahead of a May update.
