Outage in Datadog US3
Delayed evaluation of RUM and Logs monitors and issues affecting RUM data collection
Resolved MajorIncident Report
Summary AI Generated
Datadog US3 experienced a 49-minute incident affecting browser-based data collection, including Real User Monitoring (RUM), Browser Logs, and CSP reporting, along with delayed monitor evaluations for Logs and RUM. The issue caused intermittent connection failures and minor data loss for a subset of customers in a single US3 availability zone. A fix was implemented, monitor evaluations resumed, and the incident was fully resolved.
We are currently investigating an issue affecting browser-based data collection (Real User Monitoring and Browser Logs) for some customers in the US3 region.
Customers may experience:
- Intermittent connection failures when the browser SDK sends RUM, Browser Logs, or CSP report data
- A small portion of browser telemetry not being delivered during the affected window
- Delayed monitor evaluations that rely on Logs, RUM, and Browser Logs
Our engineering teams have identified the cause and mitigation is in progress. Impact is limited to a subset of traffic in a single US3 availability zone, and systems are recovering.
We will provide further updates as the situation progresses.
