Seattle Network Elevated latency to China

We're currently seeing significantly elevated latency and some packet loss to China from our Seattle network when routing outbound via AS4837. This is caused by a fiber cut in China Unicom's network in San Jose, this should be resolved soon.

Our CMIN2 network is unaffected apart from a small latency increase.

  • This was partially resolved as of 06:26 UTC, lately will still be elevated by 20ms but should decrease shortly.

    Seattle Network Degraded China network performance

    We're currently seeing degraded network performance to China, affecting both AS4837 and China Mobile International (CMI) routes. We are not sure of the cause although it is likely due to fiber cuts between the US and China as it has been with previous incidents. The previous incident lasted only a few days so hopefully this one is fine same.

    China Mobile has been re-routed to AS4837 to China due to CMI having even worse performance at peak time.

  • This has since stabilised.

  • We've changed China Mobile back to using CMI as it seems a bit more stable now.
