10 Notable Cloud Outages And What Caused Them


Amazon Simple Storage Service (S3) was taken down for two to three hours after the site received too many authentication requests in February 2008. In a posting explaining the outage, Amazon wrote that the elevated levels of authentication requests started from one location around 3:30 a.m. Pacific Time. Then, around 4 a.m., several other users increased their volume of authentication calls, pushing the service over maximum capacity. The issue was resolved around 7 a.m.

In July 2008, Amazon S3 was hit by another wave of outages, one lasting as long as 8 hours.

In both instances, several services using Amazon S3, such as Twitter, were taken down in the outages.
