vultr vps evaluation (Japanese VPS, 512m memory)

I purchased a VPS from Vultr’s Japanese data center and simply wrote a review of Vultr. If you want to know more about the situation, you can ask questions about the situation of Ultr’s VPS in the comments. I will try my best to answer as much as I can. My personal evaluation of ultr's Japanese VPS is that the G port is very powerful, the SSD is still very good, and it is very cost-effective among Japanese VPSs. Some people say that the traffic is too small, but I personally think this is the fault of the person in charge! Official website: http://www.vultr.com
