Elevated error rate on capture + processing lag
Resolved - This incident has been resolved.
Jun 2, 11:47 UTC
Monitoring - Capture latency and error rates are back to nominal on both regions. We are backfilling through the ingestion backlog now.

Between 8h15 and 11h GMT, the event submission success rate was averaging 91% on the US region. Thanks to client-side retries in posthog-js and most other SDKs, we expect the event loss ratios to be lower than this.
Jun 2, 11:13 UTC
Update - The EU region is fully operational.
The US is still experiencing an elevated event capture error rate, mitigations have been deployed and should fix this shortly. Events successfully captured are currently processed with a delay >30 minutes.
Jun 2, 11:02 UTC
Identified - We are investigating elevated event submission latencies on both regions. Some partial data loss might happen.
Jun 2, 10:48 UTC
Jun 1, 2023
Scheduled Maintenance for Posthog Cloud US
Completed - We have completed our migration and everything is working as expected. All systems are reporting normal operation. We have a backlog of events to process so they will be delayed while we catch up. We expect that will take around 15 minutes
Jun 1, 11:20 UTC
Update - Maintenance work is on-going. We are starting to come back online but there may still be occasional 500 errors until everything is finalised, we expect 30-60mins until everything is complete
Jun 1, 10:58 UTC
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Jun 1, 10:00 UTC
Scheduled - Posthog Cloud US will be undergoing scheduled maintenance. During this we'll pause ingestion. No events will be lost.

Data Processing Delays - Reporting Tools Affected
Resolved - We've spotted that something has gone wrong. We're currently investigating the issue, and will provide an update soon.
May 30, 17:23 UTC
Update - A small portion of the traffic is still experiencing ingestion delay, so we'll keep this status page open until we're full caught up.
May 30, 15:38 UTC
Update - We processed all of the events we stashed away this morning, all analytics events should now be processed with nominal latency.

We will monitor the situation for a bit longer before closing this incident.
May 30, 13:15 UTC
Monitoring - Events submitted in the last 30 minutes should be ingested without delay or duplication, some events from earlier have been stashed in a separate topic and are slowly being backfilled.
May 30, 11:45 UTC
Identified - We detected a significant amount of duplicated events going to ClickHouse. While these events will be deduplicated, they affect insight quality on recent events.

Mitigation work is ongoing, and as part of it are currently delaying part of the traffic. No data is lost.
