# AWS - **期号**: SRE Weekly Issue #45(2016-10-23) - **作者**: — - **链接**: http://status.aws.amazon.com/ ## 简介 Among many other sites and services, AWS experienced an outage. They posted an unprecedented amount of detail during the incident in a banner on their status site. Their status page history doesn’t include the banner text, so I’ll quote it here: > These events were caused by errors resolving the DNS hostnames for some AWS endpoints. AWS uses multiple DNS service providers, including Amazon Route53 and third-party service providers. The root cause was an availability event that occurred with one of our third-party DNS service providers. We have now applied mitigations to all regions that prevent impact from third party DNS availability events. Nice job with the detailed information, AWS! ## 正文 > ⚠️ 抓取失败:HTTP 503
