案 Notice
HKG-1 withdrawn from three peers
HKG-1
An automated rebuild of our prefix lists dropped the HKG-1 /22 from what we announce to three of four transit partners. From 14:06 to 14:37 UTC roughly 70% of inbound paths to Hong Kong went dark. Instances kept running and the private ring was unaffected, so traffic to the other five metros never stopped; nothing rebooted and nothing was lost. Cause: the rebuild read a stale inventory export, and we pushed it to all four edges at once. Since then a prefix list that shrinks by more than one prefix is refused without a second reviewer, edges take changes one at a time ten minutes apart, and an off-network probe alarms when any metro loses a transit path. Credits were applied on 12 July.
