Is AWS Lambda down?
Current AWS Lambda status is UP

We continue to experience elevated API error rates in a single Availability Zone (usgw1-az1) in the US-GOV-WEST-1 Region. We are working on multiple parallel paths to mitigate the issue. Instances currently running remain unaffected, however, API calls to create, modify or terminate the instances in the affected Availability Zone are not working. APIs calls directed to launch instances targeting the non-impacted Availability Zones are working. While we do not have an estimate for recovery at this time, we are tracking the progress and will provide you with another update by 11:45 AM PDT.

We continue to investigate increased error rates and latencies for the DynamoDB APIs in the US-WEST-2 Region. We have seem some improvement in error rates over the last 15 minutes but customers may still be experiencing errors. We continue to work on resolving the issue and will keep you updated on our progress.

We continue to work on resolving the error rates and increased delays in network propagation for newly launched EC2 instances in a single Availability Zone (use1-az2) in US-EAST-1 Region. We have identified the reason for the three cells that are seeing slower recovery and are currently working on resolving the issue. Once done, we should see an improvement in network mapping propagation times over the course of the next 1 to 2 hours. We’ll continue to provide regular updates.

We continue to progress toward resolving the increased networking latencies and errors affecting Availability Zones (usw2-az1 and usw2-az2) in the US-WEST-2 Region. At this time, we are approximately 50% completed with the update to address resource contention within the subsystem responsible for network mappings propagation in the usw2-az2 Availability Zone. Once we complete the update in usw2-az2, we will then move on to usw2-az1. Our current expectation is to have both Availability Zones fully resolved within the next 60 to 90 minutes, and we will continue to provide updates as recovery progresses.

We can confirm increased networking latencies and errors affecting multiple Availability Zones (usw2-az1 and usw2-az2) in the US-WEST-2 Region. We have identified a potential root cause of the errors and are attempting mitigations. Early signs are this mitigation is reducing error rates and latencies. We continue to work towards a full root case and recovery.
