1) I get why Chinese users want to use VPN (to escape GFW). However what I do not understand is - why use a USA-based VPN (or VPS)? Packet loss between mainland China and USA is quite crazy during the daytime, however China-HK or China-Singapore is quite good from what we can see. So the question is, why not use a Singapore or HK-based VPN instead of USA-based one? (Let's imagine for a moment that cost is the same as in the USA)
2) Is there something special about internet connectivity in Shanghai? Looks like the most packetloss is happening on routes to/from Shanghai.
3) What is common between a VPS and a knife?
