Increased Error rates and Latencies

6:20 AM PDT We are investigating increased error rates and latencies affecting multiple services and the AWS Console in the SA-EAST-1 Region.

6:39 AM PDT We can confirm increased error rates and latencies for some services within the SA-EAST-1 Region. The AWS Management Console is also experiencing elevated error rates as a result of this issue. The root cause of the issue appears to be elevated network packet loss which is affecting some AWS service APIs. The EC2 network, and existing EC2 instances, are not affected by this event. Some services have seen improvements in error rates as a result of mitigations taken by engineers, but we continue to work towards full recovery.
