What is the difference between Linode Japan Data Center JP1 and JP2?

Linode Japan has two computer rooms, namely JP1 and JP2. There is not much difference between them. For users in mainland China, the biggest difference may be that the routes they take are different:

Tokyo (Japan 1): http://speedtest.tokyo.linode.com/100MB-tokyo.bin

Tokyo (Japan 2): http://speedtest.tokyo2.linode.com/100MB-tokyo2.bin

To explain, due to the inaccurate IP database, the last IP of JP2 above was as low as the Netherlands. In fact, that was a mistake. Don’t worry, Japan still hasn’t gone to the Netherlands!

The biggest difference: JP1 uses KDDI and JP2 uses NTT. This is the key point!
