On the measurement that you provided the packet loss doesn't carry through to the final hop, so surely it's more likely what you're looking at here is control plane rate limiting rather than true packet loss?

Any contacts with either Akamai or NTT here ?
This is kind of important as this is affecting three of our RPKI publication servers (servers which I have de-priorized in Route53 to prevent any issues for RPs)
I have a ticket open with Akamai but I'm not directly an NTT customer so any help is appreciated.
A sample MTR report, see between hops 7 and 8. Funnily enough this is periodic and has a cycle of between 15 and 25 minutes.
