cbvps 1GB memory SSD hard drive Hong Kong NAT OpenVZ VPS evaluation

Details: cbvps: 2.8 yuan/month/256MB memory/50GB space/300GB traffic/NAT/OpenVZ/Hong Kong I bought the HK2 NAT VPS with an SSD hard drive. From the test, it seems that there is no bandwidth limit, which is awesome! I just hope it can last for a long time and not be a flash in the pan.
