Looking for Peering Contact at AS16509

Hi, I'm trying to connect with someone responsible for managing peering relations in EU for AS16509 (Amazon). Unfortunately, several attempts to reach them via the address on peeringdb (peering-emea@amazon.com) have been unanswered. Greatly appreciate if an appropriate contact could kindly reach out to me off-list. -- W. Bontekoe Principal Site Reliability Engineer
