Seattle Network China network performance

We're currently seeing significant congestion on the China AS4837 route, resulting in packet loss and high latency, this is likely due to a fault in the China Unicom network such as a fiber cut. We do not have an ETA for them resolving this currently but we hope it won't take long to fix.

Seattle Network Degraded China network performance

Our Seattle network is seeing degraded performance to/from China resulting in higher latency and packet loss due to China Unicom, who we use for our network to China (including Telecom, Unicom and Mobile), suffering backbone issues.

The cause is a fiber cut in the APCN-2 submarine cable between Shanghai and Japan which China Unicom uses for a lot of their traffic. China Unicom is working to repair but has provided no estimated fix time yet.

  • Service appears to have returned to normal.

  • Performance appears to have degraded again as of at least 2am UTC 11th July, we're continuing to monitor.

  • Service has now returned to normal.
