Update

Splunk is actively monitoring an ongoing operational issue in the AWS US-EAST-1 (N. Virginia) region that is causing intermittent service degradation across multiple AWS services and impacting several Splunk Cloud Platform environments.

While steady recovery is being observed across Splunk's cloud infrastructure, customers hosted in US-EAST-1 may still experience latency, delayed search results, or reduced availability of certain Cloud functions until AWS infrastructure fully recovers. All other Splunk Cloud regions remain fully operational.

Splunk will continue to provide updates as AWS progresses toward full service restoration.

Identified

We are aware of an outage impacting multiple AWS services in the US-EAST-1 region. This is affecting several Splunk Cloud Platform environments that rely on these AWS services. Splunk users may experience delays or errors in search execution, data ingestion, or app functionality for stacks hosted in the affected AWS region (US-EAST-1).

According to AWS, they have narrowed down the source of the network connectivity issues to an internal subsystem responsible for monitoring the health of their network load balancers. AWS has implemented throttling for new EC2 instance launches to aid recovery and is actively applying mitigations. https://health.aws.amazon.com/health/status?path=open-issues

Splunk is continuing to monitor the situation closely and will provide updates as AWS progresses toward full service restoration.
