Incident Report: Exercises, Cleanups, and Evacuations (opens in new tab)

On December 5th, 2025, we suffered a major outage in our EU region, with the last recovery steps for it extending until December 17th, 2025. For multiple hours, all of Honeycomb’s event ingestion endpoints were down. Most of the duration was spent in a degraded mode where only Activity Log data was impacted. A general timeline is available on our status page, but in this report, we’ll look at a broader analysis of what happened.
