Amazon Resolves Service Outage That Knocked Websites Offline

Amazon.com Inc.’s cloud-computing arm said it resolved an outage that had disrupted a swath of companies and organizations, including Southwest Airlines Co. and New York’s transit agency.

Amazon Web Services are now “operating normally,” according to its status page on Tuesday evening. The company said it began investigating “increased error rates and latencies” in one of its data center clusters shortly after 3 p.m. New York time. The failures affected the company’s US-EAST-1 region, which is centered in northern Virginia and is Amazon’s most important data center hub.
