I hear that their process for updating the status page involves S3.

it would appear that you are correct

"The dashboard not changing color is related to S3 issue. See the banner at the top of the dashboard for updates." https://twitter.com/awscloud/status/836656664635846656

I very seriously thought that it was a joke to say that S3 was needed to show the red icon, but apparently they can't update the dashboard about the status of S3 because of S3.
