This sounds like arp cache. And can be "fixed" by arping (forced arp responses without a who has)



Yup, EC2 instances should be issuing a gratuitous arp on startup. I've seen the same thing on subnets with a lot of DHCP churn due to constantly rebooting embedded devices.


Pretty much textbook symptoms of arp-caching.
