It looks like Amazon's port Ethernet6/1/1 on the MICE Core switch has some pretty significant errors.

Assuming the MICE ports are clean, it is probably worth following up with the Amazon NOC, peering-to@amazon.com <mailto:peering-to@amazon.com> . They did some work on their Minneapolis peering routers recently though I'm not sure what they were doing.

Good Afternoon, I've been trying to track down a strange packet loss issue when a customer of mine is downloading files from S3 in the east region. 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 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!
