Is Amazon Elastic File System down?
Current Amazon Elastic File System status is UP

We are currently investigating elevated error rates and latencies for file system requests experienced by EFS mount targets in a single Availability Zone (usgw1-az2) in the US-GOV-WEST-1 Region. EFS mount targets in other Availability Zones are unaffected, so you can continue to access regional EFS Standard file systems using those.

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 (use-az2) in US-EAST-1 Region. For AWS services, we have worked to mitigate impact by shifting network traffic away from the affected Availability Zone (use-az2). For customer applications, if you are able to shift away from the affected Availability Zone (use-az2) it may help to mitigate the impact as we work to identify the root cause and resolve the issue.

We continue to see recovery of the issue causing increased networking latencies and errors affecting Availability Zones (usw2-az1 and usw2-az2) in the US-WEST-2 Region. We’re continuing to monitor network mapping latencies and will provide a final update once all has been confirmed to be operating normally.

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 are working to accelerate the rate at which Lambda asynchronous invocations are processed, and now estimate that the queue will be fully processed over the next hour. We expect that all queued invocations will be executed.
