如果我等待一两分钟，该网站来很好。很明显，这是一个首要问题。任何人有任何想法如何解决这个问题？

我的配置：

• MVC 4
• .NET 4.5
• RavenDB 2.0.2360

更新：的Azure团队正在研究这个作为Azure网站可能存在的缺陷。只要我听到任何消息，就会有更新。

证实了这一点，如天青网站的错误，它现在已经推出出。我没有任何额外的细节，但该网站现在可行（2013年8月30日），并且我没有对代码做任何结构性更改。

Answer 2

看看事件日志，它会给你更多的信息。 它看起来像东西是防止日志适当写入，检查权限，特别是，你可能有CREATE_FILE权限，但不能写权限
