“Amazon Web Services has attributed a 44-minute outage in part of its Northern Virginia data center last week to the failure of power supply in one “availability zone” in the data center, which was soon followed by a second failure of a component in the redundant system.

Users of the Amazon EC2 cloud with workloads in Amazon’s Northern Virginia data center experienced problems early in the morning of December 9, with some operations in a part of the data center interrupted during a five-hour period.

Amazon started notifying customers of a problem at 4:08 a.m. Eastern. By 9:41 a.m., it’s Amazon Service Health Dashboard reported that “we have completed recovery of most instances affected by this event.”
