我们已经设置了一个Amazon S3存储桶来管理图像/文件。我们在不同时间在IIS 7.x上运行的Web应用程序必须使用Amazon S3 API / SDK从存储桶中提取文档。它大部分时间都在工作，但偶尔（每天几次）我们的文档请求失败。
以下是异常消息：
System.Exception: An error occurred here with the message 'Amazon.Runtime.AmazonServiceException: A WebException with status ConnectFailure was thrown. ---> System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 52.218.144.25:443

我们增加了RAM / CPU，但我们仍然会出现偶发故障。我们已经增加了重试次数和超时时间（10分钟），但仍然看到这些例外/失败。
让其他人看过这个问题/决议吗？
