中国联通拒收电信CN2的国际路由

China Unicom now confirms they will not accept any China Telecom CN2 international routing incl. customers.

This will impact all CN2 customers, including existing, permanently.
CT will peer CU overseas to solve this.

=====
DMIT experience and plan:

As everyone sees in HK and TY, the peer between AS4809/AS23764 and AS10099 is congested.

DMIT will access China Unicom in HK, TY, and LA to improve the network quality for China Unicom customers.

=====
DMIT observed network packet loss for China Unicom; it was caused by the above reason.

Since LAX.Pro is CN2 GIA guaranteed; and LAX.EB is CMIN2 guaranteed;

DMIT wasn’t planning to use any other networks on the above network profiles.

Based on the current situation, at least we will bring China Unicom access for inbound direction. (CU > DMIT.)

We will keep you posted.

中国联通现已确认，他们将不再接受任何中国电信CN2国际路由，包括现有客户。这将永久性地影响所有CN2客户。中国电信将通过海外对等连接中国联通来解决此问题。

=====
DMIT的经验和计划：

正如大家在香港和东京所见，AS4809/AS23764与AS10099之间的对等连接已出现拥堵。

DMIT将在香港、东京和洛杉矶接入中国联通，以改善中国联通客户的网络质量。

=====
DMIT观察到中国联通的网络数据包丢失，这是由上述原因引起的。

由于LAX.Pro是CN2 GIA保证的，LAX.EB是CMIN2保证的，DMIT并未计划在上述网络配置中使用其他网络。

基于当前情况，至少我们将在入站方向上引入中国联通的访问（中国联通 > DMIT）。

我们会持续向您更新情况。
