PCCW will become the main ISP to connecte with China Telecom AS4134 in PVM.n2 network.

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.
- At the same time, we will also launch the hosting service on N2 network, using the full-featured Plesk panel, and use multiple backup IP links to ensure service availability.

Network recoverd. Including PCCW

DDoS Firewall Firmware Update, HKIX and China Mobile's network will be affected

Due to Huawei's Anti-DDOS firewall firmware bug, HKIX and China mobile network are unstable.

At present, it has been repaired.

Routing Adjustment Noticed:

China Mobile's IPv6 can now establish a direct connection with us.

Since we are unable to conduct the whole network test, please send us a support tickets if your [China Mobile] IPv6 network does not establish a direct connection with us.

We will try best to make it conncet directly.

For China Unicom, China Telecom, CERNET. Our Local Loop with CW AS1273 has been completed. Vodafone Hong Kong is currently on vacation and cannot complete the IPT delivery. One more moment.

The route we expect:
AS4134/4837 - AS2914 - AS1273 - DMIT
AS23911 - AS1273 - DMIT
