Our Seattle network is seeing intermittent packet loss for our 20Gb/s DDoS protected IPs. We are aware of the cause and are working on resolving with our provider.
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.
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.
