\> **Oct 20 10:03 AM PDT** We continue to apply mitigation steps for network load balancer health and recovering connectivity for most AWS services. Lambda is experiencing function invocation errors because an internal subsystem was impacted by the network load balancer health checks. We are taking steps to recover this internal Lambda system. For EC2 launch instance failures, we are in the process of validating a fix and will deploy to the first AZ as soon as we have confidence we can do so safely. We will provide an update by 10:45 AM PDT.
