YouHi 写了: 昨天 13:21At a high level, the issue stemmed from two programs competing to write the same DNS entry – essentially a record in the internet’s phonebook – at the same time, which resulted in an empty entry. That threw multiple AWS services into disarray.

牛河梁 写了: 昨天 13:49你的机器不是每次都去DNS拿IP。拿回来缓存一段时间过期以后再去拿。所以即使DNS记录更新了。你的机器用的IP还是错的。除非手动刷新。但问题是十万百万计的(中间)服务器谁去手动刷新啊。
一个DNS改错了,会影响这么多服务?
