我们在生产方面一直面临这个问题。现在，每当将通知发布到所有移动应用程序和桌面应用程序时，就会发生此问题。在通知中，有一幅图像被缓存在CDN（Akamai）中。因此，许多用户都收到以下异常。我试图找出问题所在，但很多人说这可能是由于 设备上的网络问题，但我的问题是XXXX.XXXX.com的DNS已解决为akamai ip（117.239.141.27）。因此，这应该不成问题。此外，我和Akamai的人一起工作，他们最终找不到任何问题。所以，我有以下问题：
1）我如何找出导致此问题的原因？其次，有人在高峰流量时遇到过类似的生产问题吗？
2）如下面的堆栈跟踪所述，我是从crashlytics获得的。在少数情况下，我们会获得专用客户端IP（192.168.1.33），为什么会这样呢？ 不应将客户端的公共IP登录到crashlytics中。
