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).
