KURUN Cloud is a VPS company established back in 2019. They are an LIR of ARIN. From the website, I would guess that a group of Chinese people launches it, but headquartered in California, US.
They have a great deal, you get 1 vCPU core, 1 GB RAM, 10 GB Disk for just 3$/month, and very good networking to China (it’s very obvious that this machine is the best choice for proxy.
The ancient benchmark here is for you.
As for the route, China Telecom gets CN2 GIA for both ingress and egress (relative to the machine), China Unicom gets CUII & CUG (AS10099 + AS9929) for both ingress and egress, and China Mobile gets CMI for ingress and CUII & CUG for egress. As for the international (inbound & outbound else from China), it’s mostly Cogent. You will need to try it yourself, I didn’t tracerouted it.
Should you buy it then? Well, if you are in China, then heck yeah. 3 bucks are like nothing in today’s world. Setting up a proxy server and then using it would be a perfect choice. But it’s worth noting that this offer is out of stock as of now. They restock this one a few times a day, so keep this in mind. You can also subscribe to some channel that tracks it, and once it’s back in stock, you can pay for it immediately.
