I have 3 small VPS servers hosted by i-83 in Auckland. All have a dedicated /64 IPv6 but shared IPv4 (185.121.168.22).

I have noticed that IPv6 is routed via the US West Coast. I also noticed this issue on Voyager. Wondering if the host may be at fault here - any ideas?

PS: Speedtest servers on akl3.qh for testing purposes: IPv4 IPv6

These are the IPv6 subnets and traceroutes:
