What is Shadowsocks?
Shadowsocks is a protocol with added encryption and packet hiding functionality based on Socks5. Compared to conventional VPNs, Shadowsocks maintains high-speed and stable communication however is less effected by internet censorship. UCSS uses the latest version of Shadowsocks and ShadowsocksR.
What is a CN2 server?
It is a global network developed by China Telecom, which refers to an ultra high speed network that connects directly to Chinese internet providers without going through other servers. Because it is connected directly, it can communicate with high speed and low Ping value. Imagine the usual internet as an ordinary road and the CN2 line as a highway. Due to the cost, general VPN providers are not commonly used.
What is the UCSS speed?
We are working for reducing the stress of the Internet in regulated areas as much as possible. We think very important about speed and Ping (server response speed), and all servers used in UCSS are premium server (Available in 1Gbps dedicated bandwidth server) that direct route to China. Youtube and other streaming videos ensure the speed with which you can watch without problems on the slow Internet.
Why is the monthly traffic limited?
UCSS is a premium service for customers considering that service quality is more important than price. Therefore, we provide expensive high-quality lines that most common VPN providers can’t provide for a reason of cost savings. If these expensive high-quality lines were provided under the same conditions common VPN provider offers, such as ‘unlimited traffic + simultaneous connections for 3 to 6 devices’, the service fee would unrealistically skyrocket and most of the customers can’t afford it.
So, our service is based on monthly traffic to offer expensive but stable lines to all customers at a reasonable price.
In addition, UCSS never limits the bandwidth of communication but only monthly traffic for all customers to be able to enjoy the premium service fairly.
