I have a wordpress site on Cloudflare, usually working well - i just noticed that i get a very high ping when i have ipv6 enabled on my router here locally - i’m on fiber optic so fast 1gbps connection.
With ipv6 enabled i get 150ms ping to my server
With ipv6 disabled i get 4-6 ms ping to my server (great)
I did a check with nslookup -class=chaos -type=txt id.server 18.104.22.168 and that returns the correct nearest server to me.
When i do trace route to my site with ipv6 on, at some point there’s a hop that jumps 150 ms. By doing a trace on that very hop, you end up on Mauritius??
