嗨kamornpisit siriworathun，

Hi kamornpisit siriworathun,

此问题可能是由不同的问题引起的，例如:
•网络请求需要很长时间
•应用程序代码或数据库查询效率低下
•使用高内存/CPU的应用程序
•应用程序由于异常而崩溃

因此，一些其他详细信息将有助于正确识别问题的根本原因.在此问题之前进行了任何更改吗?听起来直到上周一切都运转良好.您的网站和数据库位于同一个资源组中吗?地点? 您是否已经将始终打开"设置为打开"?为您的网络应用程序?您是否为网站启用了诊断程序?如果尚未启用它，则可以按照此

This problem can be caused by different issues like:
• network requests taking a long time
• application code or database queries being inefficient
• application using high memory/CPU
• application crashing due to an exception

So some additional details would be helpful in correctly identify the core cause of the problem. Did make any changes prior to this issue? It sounds like everything was running well until last week. Is your website and DB in the same resource group & location? Do you already have "Always On" set to "On" for your web app? Do you have diagnostics enabled for your website? If you haven't yet enabled it, you can do so by following the steps in this documentation. After enabling it, turn on failed request tracing- it provides detailed information on failed requests, including a trace of the IIS components used to process the request and the time taken in each component. It is useful if you are attempting to increase site performance or isolate what is causing a specific HTTP error to be returned.
