Here’s What Amazon’s Outage Looked Like

Updated: Amazon Web Services (s amzn)  has put the outage behind them and now are getting back to normal, according to the latest status update from Amazon Web Services on its Service Health Dashboard. The outage that affected a hundreds of applications running in the provider’s US-EAST region is almost resolved, more than 24 hours after a “networking event” took down a number of popular services, including EC2, Elastic Block Storage and Relational Database Service.

Here’s what AWS had to say this morning:

8:49 AM PDT We continue to see progress in recovering volumes, and have heard many additional customers confirm that they’re recovering. Our current estimate is that the majority of volumes will be recovered over the next 5 to 6 hours. As we mentioned in our last post, a smaller number of volumes will require a more time consuming process to recover, and we anticipate that those will take longer to recover. We will continue to keep everyone updated as we have additional information.

Here’s what the outage looked like according to Cedexis, a company that measures response times across hundreds of networks worldwide. The first graph gives an idea of normal Amazon EC2 response times over the last 30 days, but notice the US-EAST region start to spike at April 20. The second graph shows network performance over the first 24 hours of the outage, while the second and third graphs give the last 24 hours and the last 60 minutes, respectively.
