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.
