Incident History for Amplitude

The data processing delay has been resolved, and all pipelines have caught up. The fix has been validated, and the impacted components (Data - Data Processing, Data - Event Streaming, Data - Data Export) are now functioning normally. The incident has been closed.

A fix for the data processing delay has been implemented and we are currently monitoring the results. The impacted components include Data - Data Processing, Data - Event Streaming, and Data - Data Export. We are maintaining the 'Monitoring' status while we validate the fix and ensure data synchronization.

The data processing delay has been mitigated, and the pipelines are currently catching up. A full update to the status page will be provided once all data is processed and synchronized. The issue initially reported on August 14, 2025, at 17:41 PDT.

We are continuing to investigate the data processing delay impacting realtime and batch pipelines, which affects data processing, event streaming, and data export functionalities. The initial report occurred on August 14, 2025, at 17:41 PDT; this update was posted at 18:17 PDT.

We are actively investigating a delay in data ingestion within our realtime and batch pipelines. This impacts data processing, event streaming, and data export functionalities. The issue was first reported on August 14, 2025, at 17:41 PDT.

Snowflake import delays caused by a temporary ingestion failure have been resolved. Affected components include Data - Data Processing. Further details regarding the resolution can be found in previous updates at https://stspg.io/f7cv7ypg0v06.

Snowflake imports remain delayed due to a temporary ingestion failure. Failed imports are currently being reprocessed, with recovery time estimated between a few minutes to several hours based on import size. A further update will be provided once all re-imports are complete.

Snowflake imports experienced delays between 9PM on August 7th PST and 10:20AM on August 8th PST, resulting in delayed data ingestion. No data was lost. The root issue has been resolved at 10:20AM PST, and new imports are functioning. Work is underway to recover the failed imports, with an update to follow.

All Session Replay services are now fully operational. The system is stable and functioning as expected from a customer perspective. While additional improvements will be implemented in the coming weeks to further harden the ingestion system, the immediate incident has been resolved.

Session replay ingestion is back to normal processing, but recovery efforts for replays during the incident are still underway.

Session replay and heatmaps were affected by an issue from 4:55 AM PT to 7:30 AM PT, but have been stable since then. The root cause is still under investigation.

We switched to a new underlying queuing cluster at ~7:31 AM PT, which should resolve 5xx errors on session replay tracking endpoints and restore normal processing of new session replays. However, session replays sent between 4:55 AM PT - 7:30 AM PT may be missing or unprocessed. Heatmaps were also affected as they rely on the same infrastructure.

We are investigating session replay ingestion issues causing ~10% rejection rates and processing lags in the US cluster.

Amplitude users may experience missing session replay data due to an ongoing ingestion issue.

Scheduled maintenance for Amplitude infrastructure has been completed.

Infrastructure maintenance is complete, and all systems should now be fully operational.

Scheduled maintenance is currently in progress for multiple Analytics and Data components.

Infrastructure maintenance is starting in 60 minutes, affecting multiple Analytics and Data components.
