Alibaba Cloud's VPS host has always attracted me to use it because of its low price and convenient and practical backend control panel. I had always put wzfou.com on Alibaba Cloud Hong Kong VPS, but during the use, I gradually discovered two things. Problems: First, the IO read and write speed of the VPS host is too slow, causing SWAP to run very slowly after the memory is exhausted. Second, the Alibaba Cloud VPS host will be intermittently inaccessible for users of China Mobile and China Unicom (a small number of users reported on China Telecom). The specific manifestation is that the website can be pinged, but the web page cannot be opened. A friend also discussed this issue with me in the comments of this article. It is said that the inaccessibility is caused by turning on HTTPS. Slow IO read and write speeds lead to memory exhaustion and affect WP background operation. This can be solved by restarting regularly, but the intermittent inaccessibility is really "unbearable". A friend introduced that Alibaba Cloud Japan’s VPS host in Tokyo was open for purchase and the price was quite cheap, so he moved the website to Alibaba Cloud Japan VPS last month. I tried the Alibaba Cloud Japan VPS host and found that Alibaba Cloud Japan uses SoftBank of Japan and NTT lines of Hong Kong. These two lines are currently ideal for visiting China and Japan. However, the hard disk IO read and write speed is still so "happy", and Alibaba Cloud Japan VPS also charges separate traffic fees, which is not suitable for high-traffic applications.
