From China Telecom Group Beijing:
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.
