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

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

   resolved
   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.
