I checked a recent packet capture and located only 93 requests from the ASN “Google”. A derisory value compared to asn requests “AMAZON-02”, which in the same 20-second period counted 15442 packets (6.4% of all ntp traffic received).
A curious fact, is that although my server is present in pool USA, it receives a huge amount of requests from Amazon servers in other countries like UK, Ireland, France…
This indicates that many Amazon servers are configured to use the US pool instead of your own country pool or the global pool.
