从豆瓣宕机看IDC单点问题

[不指定 2008-10-31 17:26 | by 张宴 ]
  豆瓣从上午11点开始宕机(见:http://blog.douban.com/douban/2008/10/31/139/),到现在已经超过6个小时了。

  豆瓣的服务器托管在京东某BGP机房,我在那个机房有机器,试了试,从IDC内部是能访问的。另外,和豆瓣同一IP段的http://59.151.41.22/从外部是能够访问的。所以,我估计是IDC机房内豆瓣那一组线路的问题。

  看来,多IDC异地容灾还是很重要的。IDC不出问题则以,一出问题,就成了最大的单点。

  IDC机房内部到豆瓣路由是通的:

  从IDC机房内部是能访问豆瓣的:

DDos ,

和单点有什么关系
张宴 回复于 2008-11-1 16:28
如果有多个IDC的话,遭受DDos攻击,切换机房也比较快。
现在豆瓣的IP是211.147.5.57,应该是迁机房了,北京电信通的三元桥机房。

IDC容灾是大公司才能享受的,这个在技术架构上要求也比较高。
