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 Seattle - AS4837 congestion to China

    We have seen major congestion from AS4837 to China today, as a result, we have moved routing to AS4134 as this is performing considerably better, both in terms of latency and throughput bandwidth. We will switch back to AS4837 once it has been repaired, we have received no estimated repair date yet.

  • AS4837 appears to be performing normally now so has been reactivated.
