AWS says still experiencing elevated errors across availability zones in US-EAST

In a series of updates on the status of AWS services, Amazon Web Services stated: “We are making progress on resolving the issue with new EC2 instance launches in the US-EAST-1 Region and are now able to successfully launch new instances in some Availability Zones. We are applying similar mitigations to the remaining impacted Availability Zones to restore new instance launches. As we continue to make progress, customers will see an increasing number of successful new EC2 launches. We continue to recommend that customers launch new EC2 Instance launches that are not targeted to a specific Availability Zone so that EC2 has flexibility in selecting the appropriate AZ. We also wanted to share that we are continuing to successfully process the backlog of events for both EventBridge and Cloudtrail. New events published to these services are being delivered normally and are not experiencing elevated delivery latencies… We have applied multiple mitigations across multiple Availability Zones (AZs) in US-EAST-1 and are still experiencing elevated errors for new EC2 instance launches. We are rate limiting new instance launches to aid recovery. We will provide an update at 7:30 AM PDT or sooner if we have additional information.”
