1月21日下午,国内出现大面积网络故障,部分.com网站无法访问。DNS服务商透露,故障原因为全国所有通用顶级域的根服务器出现异常,致国内大部分用户无法正确解析域名,域名访问请求被跳转到美国一个无响应的IP,对全国互联网链接造成系统性影响,估计有数十万网站受到影响。
请看相关报道:
For a period around 3 pm on Tuesday, attempts to visit many Chinese websites failed, with netizens often receiving error messages. This was due to malfunction of root servers for China's top-level domain names, the China Internet Network Information Center (CNNIC) said in a posting on Sina Weibo, the Twitter-like microblogging service.
周二下午三点钟左右,用户在访问国内很多网站时均收到错误提示,网站无法访问。中国互联网信息中心通过新浪微博表示,该问题是由于中国顶级域名根服务器故障所致。
Top-level domain names 此次网络故障 DNS 是域名系统 (Domain Name System) 的缩写,是因特网的一项核心服务,它作为可以将域名和IP地址相互映射的一个分布式数据库,能够使人更方便的访问互联网,而不用去记住能够被机器直接读取的IP数串。
