I was able to replicate this slowness on my first try. It appears that the specific node I was talking to when seeing the slow download was 54.231.233.205 and it took a couple of minutes to complete, averaging 100 KB/s. We only peer with Amazon via MICE. Hope the information is helpful, and please let us know if you find anything.

We peer with AWS via MICE and traffic to east routes via MICE. Could any of you folks peered with AWS via MICE try downloading this file a bunch of times and reports the results? <http://ofw-atomic-data-test-region-us-east-1.s3-website-us-east-1.amazonaws .com/empty_test_file_50M.txt> http://ofw-atomic-data-test-region-us-east-1.s3-website-us-east-1.amazonaws. com/empty_test_file_50M.txt Basically, we see fast transfers maybe 80% of the time and then it will be slow, like sub 1Mb slow (we can replicate the issue with iperf to an EC2 instance also). Captures show lots of retransmits, etc during a slow transfer. If I shut down my AWS peering the problem goes away. I was able to test from another client of mine connected to Arvig and I'm pretty sure I can replicate the issue from there. So, I'm not convinced it's just me. On the other hand, if there is a problem, I'm surprised no one else has noticed! Thanks!
