Core switch line-card failure in REY, row B

타임라인

1. 해결됨2026. 3. 13. 오후 10:22 UTC

   Every machine in row B has been reachable since 22:22 UTC. Duration of the outage: 54 minutes. The failed card is being replaced under an existing maintenance window; the replacement does not require another interruption. Affected machines receive the SLA extension automatically.

   All 14 affected ports are up on the surviving card. We are checking each machine individually before closing this.

   A line card in one of the two core switches in REY failed. Row B was dual-homed, but the failover on 14 ports did not complete because the standby links were still training. We are forcing those ports over to the surviving card.

   Machines in row B of REY lost network connectivity at 21:28 UTC. Rows outside B are unaffected. Engineers are on the floor.
