Increased Provisioning and Scaling Latencies

12:50 PM PDT We can confirm increased provisioning and scaling latencies for Elastic Load Balancers in the US-EAST-1 Region.

1:38 PM PDT We have determined the root cause of increased scaling latencies for Elastic Load Balancers in the US-EAST-1 Region and are working towards mitigation.

2:39 PM PDT The team is closely monitoring the issue with EC2 APIs, and continues to see reductions in scaling and provisioning latencies. Other load balancing operations, including target registrations and traffic processing are unaffected. Once the issue with the EC2 APIs is resolved, we will process the backlog of any pending operations before we observe full resolution.

3:44 PM PDT Beginning at 11:13 AM PDT we experienced increased provisioning and scaling latencies for Elastic Load Balancers in the US-EAST-1 Region. Recovery for scaling latency occurred at 1:15 PM PDT, and recovery for provisioning latency occurred at 3:35 PM PDT. The issue has been resolved and the service is operating normally.
