I have two sites both served using Cloudflare Workers. Site A is served from a nearby edge as expected, but site B is routed to all kinds of other places. Since site A is working fine and I reproduced the issue in three locations, I don’t think this is an ISP issue on my end.
My house Internet in Tokyo: SJC
My phone: ICN
Server on GCP in Tokyo: SYD
Site A goes to KIX from all three places.
Are both domains on a Free plan? I find that under certain conditions, my Free plan doesn’t hit the closest POP, but my Pro plan does.
Yes, it’s a Free plan. Is Pro officially meant to have better routing? If so, I’ll upgrade but I was happier just paying for the workers 
Currently, my Free Plans are hitting my local POP. They usually do.
But it sounds like both Site A and Site B are on Free Plans, yet they both don’t hit local POPs.
I do see that none of my free plans have the same IP addresses as another. Some are in the same Class B range (104.27.xx.xx). It could still be an ISP issue on how they route the different IP addresses.
What does Traceroute look like for Site A and Site B? At some point, their paths diverge. Go ahead and post Traceroutes if you’d like more feedback.
Site A is hitting the local POP. The KIX or NRT POP is what I would like.
Site B was also hitting the local POP until recently. I just noticed everything was slower than usual and it turned out out it was because of this.
I ran traceroute from a GCP server in Tokyo.
Site A, i.e. the good one:
traceroute to ricky.me (104.24.109.119), 30 hops max, 46 byte packets
1 172.17.0.1 (172.17.0.1) 0.005 ms 0.005 ms 0.002 ms
2 104.24.109.119 (104.24.109.119) 8.290 ms 7.615 ms 7.530 ms
Site B, the bad one:
traceroute to momocloportal.com (104.27.161.149), 30 hops max, 46 byte packets
1 172.17.0.1 (172.17.0.1) 0.005 ms 0.005 ms 0.002 ms
2 104.27.161.149 (104.27.161.149) 113.895 ms 113.949 ms 114.294 ms
That’s…one hop from your internal network straight to the Cloudflare IP address? That’s an impossibility.
I believe that the lack of hops is because GCP is directly peered with Cloudflare.
Here’s the traceroutes from my house.

In that case, both sites should show KIX when testing from GCP. Can you try a ‘curl -I example.com’ and look at the cf-ray header.
So, for whatever reason. Asahi routes momocloportal off to JPNIC instead of BBIX, and then it goes downhill from there. You’d have to find out from Asahi why they’re doing this.
ricky.me: 4f1ab1f8687adb24-KIX
momocloportal.com: 4f1ab22d28dfd0dc-SJC
I don’t know what is happening behind the scenes, but I don’t think this is an issue with just one ISP, since as I said it happens on every network I’ve tried. I don’t think AsahiNet, Google, or Docomo would take my call anyway.
At this point, you should contact Support and include a link to this thread:
Login to Cloudflare and then contact Cloudflare Support by clicking on the Get More Help button.
OK, thanks for you help
