Our Seattle AS9929 China optimised routes are currently re-routed due to high packet loss and latency seen since 07:20 UTC. We've re-routed China Telecom via AS4837 and Unicom via CMIN2.
There's likely a fiber cut or equipment failure in Los Angeles causing this, we're monitoring and will re-enable AS9929 as soon as the issue is resolved. We have not been given an estimated fix time yet, we'll update this entry if we get any updates.
