AWS NTP Server Access

Question

Doesn't AWS have a publicly available NTP server at 169.254.169.123:123? I get destination host unreachable when I ping from my local PC. I've tried using command line and powershell from 2 different computers. I'm able to successfully ping and sync NTP time with time.google.com.
*Edit* Here is the article where I found the NTP server address: https://aws.amazon.com/blogs/aws/keeping-time-with-amazon-time-sync-service/

Answer

That is a link local address and is only available from within a VPC.

In doesn't look like that address responds to ping (ICMP). It is only for NTP traffic.
