i've been noticing some Cloudflare IP's have been routing to japan instead of closer AU nodes anyone else on Spark noticed this?

these IP's for example: 104.27.143.66 - 104.18.48.190

while geekzones CF IP: 104.24.2.14 (updated IP was incorrect) routes perfectly.

What do traceroutes to affected vs unaffected IPs look like?

Spark doesn't "Peer" and Cloudflare won't buy sparks domestic transit product.

So traffic will go via AU.

Not sure if it is related, but Cloudflare do not route sites hosting with a free Cloudflare accounts on some Aussie telcos (Telstra and Optus) to the Australian servers due to high transit costs. https://blog.cloudflare.com/bandwidth-costs-around-the-world/

Nice, does IPv4 get handed off in NZ too?
