I had some issues recently with some AWS instances. Not sure exactly what is going on but on restart I see that the instance is not using the AWS NTP servers.
That results in a data leak if you have those ports open. Those other NTP servers can tell every time you start and stop your instance.
Not sure if something changed but those instance should default to the AWS NTP service.
Also it would be great if you could get a warning in the console and upon logging in via SSH that your system is not using the AWS time servers.
Follow for updates.
