We are adjusting the route for PVM.n3 network.
China Unicom still hasn't updated the routing prefix. We will make it going to PCCW first, after China Unicom update our prefix in their network, we will let China Unicom(AS4837) going to AS4809, and then going to our network by CDIA.

- CW (AS1273) IPv6 optimization for CERNET will be available with 2 weeks. Local Loop is being delivered.
- Dedicated Server will only have N3 network.
