仅在使用PHP的一台服务器上使用Amazon AWS S3文件访问超时

Since few days we are facing a problem with accessing files from Amazon AWS S3 file bucket using PHP.

We are connecting from our Linux server. From time to time file is accessed normally - latency less that 1s. But most of the times the access process is starting and never ends - timeout.

This is really strange situation, because we did not change any configuration or source code of our application. It just started few days ago.

This problem is occuring when code is executed on one of our servers. When we run it on different server or hosting - it works perfectly.

We are using standard library from Amazon for PHP.


What could be the reason?

Is it possible that AWS is banning connection from one of the servers, if there is too many read operations?

Any ideas?
