Is SignalFx US0 down?

A degradation in the performance of the Splunk APM metrics processing pipeline is causing Monitoring MetricSets to be dropped. Trace data ingest is not impacted, but service, endpoint and workflow dashboards, and other charts and detectors built from Monitoring MetricSets are impacted.

The issue has been identified and a fix is being implemented.

A fix has been implemented and we are monitoring the results.

The issue has been fixed.

Some customers may have experienced delays in alert notifications from 4 am ~ 6 am (PST), 2026. Datapoint ingest is not affected. The issue is recovered.

We are currently investigating the issue. Certain APIs may be failing and active alert pages is loading slowly. No data is being dropped or lost.

Customer impact began around 7:00 AM PDT. We have identified a fix, but a full recovery could take several hours

We are continuing to work on a fix for this issue. A full recovery could take several hours

A fix has been implemented and we are monitoring the results as backlog recovers. Alert states and event time series in the UI may be delayed while the backlog recovers.

This incident has been resolved.

Starting at 1a PDT, a small percentage of detectors may have missed firing. No data has been lost. We are investigating and will provide an update shortly.

A fix has been implemented and we are monitoring the results.

We are continuing to monitor for any further issues.

We are continuing to monitor for any further issues.

We have seen a return of a small percentage of detectors that may not be firing. No data is lost. We are continuing to investigate.

We continue to investigate an issue affecting a small percentage of detectors in US0 that may not have fired as expected. No data loss has been observed. Our engineering teams are actively investigating the issue, and we will provide another update as more information becomes available.

A mitigation has been applied for the issue affecting a small percentage of detectors in US0 that may not have fired as expected. We are observing continued recovery and are monitoring the environment to ensure the mitigation is fully effective. No data loss has been observed. We will provide another update once recovery is complete.

We have applied mitigations that reduced the impact, but recovery is not yet complete. A small percentage of detectors in US0 may still not be firing as expected due to delayed processing. No data loss has been observed. Engineering teams continue to investigate towards the additional mitigations. We will provide another update as more information becomes available.

We have identified that newly created time series in US0 may take up to 10 minutes to be included in detectors, which may delay detector evaluations for those new time series. Notification delay mean time is currently healthy, and no data loss has been observed. Engineering teams are continuing mitigation work and validating whether it clears the remaining delays. We will provide another update once validation is complete.

We continue to investigate delayed inclusion of newly created time series in detectors in US0. New time series may take up to 10 minutes to be included in detectors, which may delay detector evaluations for those time series. Notification delay mean time remains healthy, and no data loss has been observed. Engineering teams are performing a controlled rollout of affected backend components as part of ongoing mitigation work, and this is not expected to introduce additional customer impact. We will provide another update as validation progresses.
