Why are files cached on the cloudfront being served at the far edge?
Hi
I run WordPress and put a origin server in Japan.
And 75% of my website visitors come from South Korea.
Based on the location of the cloudfront, I think the cached files should be served from the Korea edge (Seoul).
But in reality, most of the requests are served from the Singapore edge.
Is there any reason why they are being served from the Singapore server instead of Korea and how can I fix this?
And
I can't find the Korea Edge in Bills, is it not available?
Thank you.

There's no way for you to control which edge location your users are going to connect to. It comes down to where the traffic routes on the internet between the user's location (which is their IP address on their ISP network) and what the network thinks is the closest point of presence. "Closest" in this case is "best IP route" which is determined by the routing protocols. These can be influenced by the ISP network administrators but you have no ability to do that (unless, of course, you're the network administrator).
If this is a critical issue please contact the support team as they can determine the network providers who are (perhaps) routing the traffic via Singapore and (again, perhaps) have a conversation about that. While we (AWS) can talk to network operators we can't force them to route traffic in any particular way.
Finally, there are CloudFront points of presence in Korea as per the list of locations.
As a side note, if 75% of your users are in South Korea, why not use the Seoul region?
Hi there. Thanks for the advice.
I'm still on the free tier of CloudFront, so I can't get support for that.
The reason I have a server in Japan is because if I had a server in Korea, it would be incredibly slow to access from overseas.
South Korean internet providers and network usage fee laws impose expensive fees or speed limits on international traffic.
For example :
Cloudflare doesn't offer a South Korea location unless i`m on an enterprise plan. In South Korea, Twitch can only be viewed in 720p.
So I think having a server in Japan is the way to satisfy both Korean and international visitors.
Have you tested your server in the Seoul region? Might be worth validating your assumptions.
