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 Seattle intermittent packet loss to China

    Intermittent packet loss of 10% on average, often 100% loss for up to 20 seconds, to China Telecom and Unicom. This is caused by the network transport provider we use for AS4837 having problems, we have sent them a message about it and are awaiting an update.

  • AS4837 has now been re-enabled.

  • We have temporarily re-routed away from AS4837 due to significant disruption to China bound traffic, we will reactivate as soon as our transport provider resolves the issue.
