Transient load-balancer issue in us-west-1

Incident Report for Ably

Resolved

Between 16:27-16:35 UTC, connection attempts to us-west-1 had an ~18% chance of being refused with an error due to a network load balancer issue. An Ably SDK will have been automatically retried to a fallback region, so an end user will have experienced no impact other than a slight increase in connection establishment latency.
