HKG EB customers,
DMIT is now bringing direct routing back for HKG.EB network profile. Incl those Lite transition instances.
Besides that, DMIT also offers direct China inbound routing EBv2.
From China > DMIT HKG EBv2
- CT: via AS4809 CN2 GIA. (By AS23764)
- CU: via AS4809 CN2 GIA. (By AS23764-AS10099)
- CM: via AS58453 CMI.
From DMIT HKG EBv2 > China CT, CU, CM: CMI AS58453.
Based on the obvious reason, the costs of CMI is sky rocket. DMIT has to revise the routing to ensure profitability, stability and prevent overselling.
For the current customers:
Whatever you order, you can keep it and keep renewing.
The inbound routing (CN->DMIT) will not be changed or routed to CN2GIA.

LAX.Pro & LAX.EB
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.
