Delayed data streams data
Resolved MajorIncident Report
Summary AI Generated
Datadog's Data Streams Monitoring (DSM) in the US1 datacenter experienced delayed or missing latency metrics for approximately 1.9 hours, which also caused monitors configured on those metrics to fail to alert as expected. No data loss occurred, though a small percentage of data from the affected window required backfilling after a fix was deployed. The incident was fully resolved after monitoring confirmed the fix was effective.
We are currently investigating an issue affecting Data Streams Monitoring (DSM) in our US1 datacenter. As a result, data stream latency metrics may be delayed or not updating for some users. If you have monitors configured on those metrics, they may fail to alert as expected during this incident. We are not aware of any data loss at this time. Our engineering team is actively working on a fix, and we'll follow up with more information shortly.
