Software bug causes major downtime

A single customer managed to bring down some of the world’s most visited websites on June 8^th. Services such as Amazon, Reddit, Gov.uk and Twitch were knocked offline for just under one hour, according to Data Center Dynamics. Although a cyber attack was discussed online during the outage, it quickly became known that the fault lied with Fastly, a major content delivery network. After all services were resumed, Fastly announced that a previously unknown software bug had caused the outage, and that the bug was triggered by a single customer making a very specific account configuration change which caused errors in throughout the Fastly network.
