Amazon EC2 was Down During 21 Minutes – March 15th, 2012

Posted by iwgcr

Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides resizable compute capacity in the cloud. As shown on Amazon Dashboard, the Amazon EC2 service was unavailable in US-East region. Customers were affected by the outage between 2:22 AM and 2:43 AM on March 15th, 2012.

Here is the message from the Amazon team:

2:40 AM PDT We are investigating connectivity issues for EC2 in the US-EAST-1 region. 3:03 AM PDT Between 2:22 AM and 2:43 AM PDT internet connectivity was impaired in the US-EAST-1 region. Full connectivity has been restored. The service is operating normally. 6:09 PM PDT We want to provide some additional information on the Internet connectivity interruption that impacted our US-East Region last night. A networking router bug caused a defective route to the Internet to be advertised within the network. This resulted in a 22 minute Internet connectivity interruption for instances in the region.
