Amazon has identified the cause of a significant AWS outage that disrupted services for numerous companies worldwide. The issue, stemming from a bug in AWS’s automation software, affected platforms such as Signal, Snapchat, Roblox, and Duolingo, as well as banking services and smart home devices like the Eight Sleep smart bed. AWS attributed the outage to a latent defect in their automated DNS management system at the US-East-1 datacentre, which resulted in an empty DNS record and necessitated manual intervention for resolution.
