我在Azure应用服务上运行最新版本的Umbraco（7.10.4）。昨天我发现我的网站显示一个空白的白页，但HTTP状态代码为200（ok），因此我的可用性测试返回正常，我没有得到任何通知，该网站几乎停机4小时：|
当我意识到我用谷歌搜索它时，原因显然是SQL查询超时了。 https://our.umbraco.org/forum/core/general/49635-Umbraco-cannot-start-Error-Republishing-Thread-was-being-aborted
有趣的是，在尝试从Umbraco获取设置页面时，我的页面中的线程被阻止（或者至少异常开始提升）。

我重新启动了网站并且它已经开始重新运行，但有两个问题：
1-如何防止再次发生这种情况？增加超时持续时间可能会有所帮助，但如果需要更多时间呢？通常，当基于云的解决方案在网站上几乎没有人时，你不会期望在3 A.M发生这样的事情。
2-如何为其设置警报？为什么回归200？！ ：|
