Amazon outage started small, snowballed into 12-hour event

Brandon Butler | Oct. 24, 2012
Amazon Web Services has almost fully recovered from a more than 12-hour event that appears to have started by only impacting a small number of customers but quickly snowballed into a larger issue that took down major sites including Reddit, Imgur and others yesterday.

But Network World reader Biju Chacko commented that he experienced a multiple-AZ failure. "This is clearly an AWS screwup - their recommended redundancy strategies are not working," he wrote in a comment.

This is the third significant outage AWS has experienced in the past two years. In late June, powerful storms that led to power outages in the mid-Atlantic region were partially the cause of an outage that then was worsened by bugs and bottlenecks within AWS's system. The company issued a detailed postmortem report after that event.

In April 2011, AWS experienced another major outage that took down Reddit, Foursquare, HootSuite, Quora and others, some for as many as four days.
