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.
