Facebook pinpoints router configuration changes for major global outage across platforms

Facebook blamed the outage on configuration changes it made to routers that coordinate network traffic between its data centres."This disruption to network traffic had a cascading effect on the way our data centers communicate, bringing our services to a halt," Facebook vice president of infrastructure Santosh Janardhan said in a post.Cyber security expert Brian Krebs described what happened as Facebook taking away "the map telling the world's computers how to find its various online properties."[caption id="attachment_9741941" align="alignnone" width="1280"] Facebook and its apps were down for nearly six hours.
