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 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.

  • This was partially resolved at 10:18 UTC and fully resolved at 11:11 UTC.

  • 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 Poor performance to China - AS4837

    Since 5am UTC, we've seen a large increase in latency and packet loss on the AS4847 network. We can see that other hosting providers using AS4837 are also impacted meaning it's likely a fiber cut or router issue on China Unicom's side at fault. We hope this will be resolved quickly.

  • This has now been resolved as of 12:10 UTC.
