There are random problems when loading pages that leave messages like:

Fatal error: Uncaught AwsCloudSearchExceptionCloudSearchException: AWS Error Code: Throttling, Status Code: 400, AWS Request ID: c6812347-faea-11e3-aacc-c743845c8fa1, AWS Error Type: client, AWS Error Message: Rate exceeded, User-Agent: aws-sdk-php2/2.6.6 Guzzle/3.9.1 curl/7.19.7 PHP/5.3.3 thrown in phar:///rn1/renderosity/builds/production_1403536223/library/AWS/aws.phar/Aws/Common/Exception/NamespaceExceptionFactory.php on line 91

and at some point every page says something like this.  Is this maybe due to the obvious upgrades to the website going on?  Hmmmm?
