ChangeIP 512MB Memory SSD Hard Drive Los Angeles Sharktech KVM VPS Review

Details: ChangeIP: $1.6/month/512MB memory/20GB SSD space/500GB traffic/KVM/Los Angeles Sharktech Someone in the TG group said that the speed in the morning was only 1M, so I paid an annual fee and tested it. Judging from the evaluation data, the performance is good and the network is also very good. 100M is no problem and you can easily watch 4k, especially China Unicom, which is surprisingly good. And the customer service response speed is good. I bought it in the morning, and the IP was blocked. I sent a TK, and it was changed in less than an hour, which is good (it feels like the customer service has changed). Such a price, such a network and service, great value!
