Here are a few reasons why:
- China’s laws and operators stipulate that home networks cannot be used for public services, so if we want to set up an NTP server in mainland China, we have to buy either a VPS or a commercial network.
- Because of our policy of subsidizing home network rates with commercial network rates, commercial network rates are extremely high.
- So it is basically impractical for an individual to buy a commercial network.
- And if you buy a VPS, the traffic/bandwidth costs are extremely high.
