Splunk の障害履歴

As part of a recent maintenance activity, some environments with ITSI may experience a rolling restart of the environment. Customers may temporarily see restart notifications or reload prompts within the UI while these activities complete.

Update: Rolling restart activities may be occurring at midnight local time for the applicable cloud provider region for some environments with ITSI. Customers may continue to observe restart notifications or reload prompts within the UI while these activities complete. Customer environments that may see restart notifications include: Splunk Cloud Platform Splunk Cloud Platform for FedRAMP Moderate Splunk Cloud Platform for FedRAMP High Splunk Cloud Platform for IL5 No customer action is required.

We have identified the cause of the rolling restart activity affecting some environments with ITSI and continue to monitor impacted environments.

This incident has been resolved.

Some customers are experiencing ingestion issues due to a DNS synchronization issue affecting HEC dash DNS records using the format http-inputs-${stack}.splunkcloud.com. HEC ingestion using the current dot-format DNS records, http-inputs.${stack}.splunkcloud.com, is functioning correctly. As a mitigation, customers using the dash-format HEC endpoint should update their upstream systems to use the dot-format endpoint: http-inputs.${stack}.splunkcloud.com. Our engineering teams are working to restore the affected DNS records through Zone DNS synchronization. We will provide another update once DNS synchronization has completed or if there is a meaningful change in impact.

Some customers experienced traditional HEC ingestion issues due to a DNS synchronization issue affecting HEC dash DNS records using the format http-inputs-${stack}.splunkcloud.com. HEC ingestion using the current dot-format DNS records, http-inputs.${stack}.splunkcloud.com, is functioning correctly. This issue was resolved for affected customers by 07:00 UTC.
