Global anycast routed to AMS

Hello, I am trying to host a DNS app and was testing the latency.

On the anycast network I am routed to AMS on both IPv4 and IPv6.
I am from Sri Lanka and I have better latencies to SIN. (around ~80ms)

Is it possible to change the region?

Below is an MTR to debug.fly.dev

Thanks.

Can you try this with IPv4? I’m curious if IPv6 and IPv4 are routing differently.

it looks like the same route.
