Amazon‘s Elastic Computer Cloud and Relational Database Service went down yesterday, interrupting service for Amazon Web Services users like Netflix, Reddit, Foursquare and Instagram. PC Mag reports that service was disrupted around 10pm but back online around 11pm. The service error occurred when network traffic was moved to a lower-capacity network instead of shifting to another router, which downed servers in Virginia.

Amazon.com, Inc. (NASDAQ:AMZN) has apologized for an outage that took place last week on websites that run on Amazon Web Services (AWS). Reddit.com was especially affected by the outage. The problem started around 12:47AM on April 21st at the Elastic Block Store (EBS) that houses some of Amazon.com’s cloud computing servers. The problem was caused by a single Availability Zone on the East Coast and it was caused by a human error.

Amazon, Inc. (NASDAQ:AMZN) Web Services customers now have the option to run cloud applications on their own dedicated hardware. While Amazon’s Elastic Compute Cloud uses virtualization, some customers may prefer dedicated hardware due to regulatory or other restrictions. The Dedicated Instances will be a part of Amazon’s Virtual Private Cloud (VPC) service.
