Power Outage Affects Amazon Customers
A power outage at an Amazon Web Services data center in northern Virginia last night knocked some customers offline. Among the sites affected were Heroku, Pinterest, Quora and HootSuite, along with a host of smaller sites. Amazon confirmed the power outage on its Service Health Dashboard, but did not offer details on the root cause of the power outage. The outage affected only one availability zone, the US-East-1 Region. The downtime led to the usual Twitter trash-talking about how major sites should spread their infrastructure across multiple Amazon availability zones, rather than relying on a single zone. Heroku indicated that its recovery efforts included shifting workloads to other availability zones.
