The backup Routing Engine is back to work.
The network is in recovering. Premium routing takes 40mins to recover.
This is a hard limit by the ISP AS4809
We are waiting for the on-site engineer to upgrade the master Routing Engine (The network is running on the backup engine now. This will not impact the network)

After inspection, the earthquake in Japan only slightly affected DMIT's data center in Equinix TY: a management node got circuit failed.
All computing and network nodes are running as expected.
Due to the particularity of the Tokyo data center, we still recommend that you schedule regular backups in this data center.
Stay safe.

Solved. DDoS Mitigation Cluster has routing loop issues. Huge DDoS used up the entire bandwidth capacity of the core router. The router tried to reset all interfaces on the PFE to "solve" this issue.
To save FIB, the DDoS Cluster has no full FIB, it shares with other tables.
We'll keep looking into this to avoid any potential problems
The DDoS is not that huge on Internet, due to the looping, it was enlarged by "TTL-times".
If the source is Windows which has 128 TTL then it will be 128 times.

DMIT has been following up on this event since Federal Communications Commission (FCC) issued the news announcement about China Telecom America (CTA).
To ensure the accuracy of the announcement and avoid misunderstanding, DMIT has not published any assumptions about this events until we got confirmation from CTA.
The FCC 214 license is needed to provide mobile, home networks, etc. in the U.S.
DMIT is also an IP Transit provider, and providing IP Transit services in the United States does not require a license. The revocation of CTA's 214 licenses will only affect its CTExcel(MVNO service).
Attached is the official statement of CTA on this event.
