Mux outage: Mux Data Collection Latency

Affected components

• Mux Data - Data Collection

1. resolvedOct 21, 2026, 23:47 UTC

   This incident has been resolved. For a subset of customers, our ingestion pipeline was unresponsive to incoming beacons at 22:04 UTC. While our SDKs are programmed to retry, there is the potential for delayed or lost beacons at and around that time. Delayed/lost beacons would disrupt our realtime metrics and alerting. Missing beacons may also result in some missing event data for views being generated at that time.

2. monitoringOct 21, 2026, 22:51 UTC

   The system has recovered at 22:28 UTC and we are monitoring the results.

3. investigatingOct 21, 2026, 22:21 UTC

   We are experiencing some latency in collecting beacons, beginning 22:04 UTC. Investigation is underway.
