Starting at 1:51 UTC we began a node drain operation to move workloads over to another node pool. This operation resulted in an unhealthy load balancer backend with no failover. During 1:51 UTC and 1:52 UTC connections to us-central1-1.gcp.cloud2.influxdata.com would have received a timeout. We immediately forced nodes back into the load balancer and services were returning to operational status at 1:53 UTC. Services were fully restored at 1:57 UTC for the us-central1-1 endpoint.
