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. We suspect there is a fiber cut in China Unicom's US network in the San Jose area, this should be resolved soon.

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

  • It has been confirmed there is major fiber cuts in the San Jose area (where we connect to China Unicom), no current estimated fix time. We checked alternative routes but they all had higher packet loss, although lower latency. We will consider switching routes if this carries on for much longer.

    Seattle Network Degraded performance to China

    We are currently seeing degraded performance (higher packet loss and lower bandwidth throughput) to China for China Telecom and China Unicom on AS4837, likely due to significant submarine fiber cuts in Asia. We're currently waiting on an update as to when a fix will be. We have changed the outbound route to AS4134 in the meantime as it has slightly better performance. China Mobile is unaffected.

  • Performance was restored and we're monitoring.
