AWS故障因DNS失败扰乱主要在线服务
摘要
AWS美国东部1区的DNS故障导致多个平台服务广泛中断，影响全球数百万用户。
2025年10月20日，亚马逊网络服务（AWS）在其位于弗吉尼亚北部的美国东部1区发生重大故障。此次中断始于东部时间凌晨3:11，原因是影响DynamoDB API端点的域名系统（DNS）故障。
此次故障影响了包括Snapchat、Reddit、Venmo、Fortnite和Roblox在内的众多知名服务，导致全球用户无法访问这些平台。AWS报告称，DNS问题在大约东部时间早上6:35得到完全缓解，服务逐步恢复正常运行。
DNS作为互联网的地址簿，将人类可读的域名转换为机器可读的IP地址。该系统的故障会阻止用户访问网站和服务，因为浏览器无法定位对应的服务器。
美国东部1区是AWS的重要枢纽，承载了其大量基础设施。因此，该区域的问题可能对依赖AWS的全球服务产生广泛影响。
此次事件凸显了集中式云服务潜在的风险，并强调了构建强大基础设施和应急预案以减轻此类故障影响的重要性。
