Seattle Network Increased latency for China

We're currently seeing increased latency to/from China for our Seattle network due to suspected fiber cuts on the US west coast, this appears to be heavily impacting China Unicom's network (AS4837) which has likely lost considerable capacity. CMIN2 should not see any impact apart from a temporary 20ms latency increase due to a re-route caused by the fiber cuts. This shouldn't take too long to be resolved.

  • The fiber cut was fixed at 4pm UTC and we can confirm everything is now looking normal.

  • Confirmed fiber cut, here is the explanation from our transport provider: There is a fiber cut between Vacaville, CA and Sacramento, CA. The fiber cut was caused by a car hitting a utility pole.

    It's likely that China Unicom is suffering capacity loss due to this same incident, there is no estimated fix time yet.

    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.
