Text of the page (random words):
college china s global internet connectivity has been notoriously bad for as long as i can remember still not any better right now not just in the sense of censorship but also in terms of connection quality for example if you have a server in the us and want to connect to it from china expect over 10 20 or more packet loss so if you set up a proxy server in another country to circumvent censorship it would be painfully slow the most popular tools back then were goagent and later shadowsocks so hysteria began as an attempt to improve my speed for watching youtube videos it s always great to see developers building something to solve their own challenges i can relate to the packet loss issue either you suffer the packet loss or you have to purchase an expensive server with cn2
