Data Processing Delays - Reporting Tools Affected
Resolved - Event processing lag is back to normal levels. Incident is resolved.
Jul 11, 00:35 UTC
Monitoring - Event processing is healthy again. Lag is coming down, but there is still a healthy back log to get through.
Jul 10, 22:38 UTC
Investigating - Our data processing infrastructure is running behind which is causing inaccuracies in the reporting tools. No data has been lost and the system should be caught up once we root cause the problem and find a resolution.

Delayed ingestion for replay and delayed processing for CDP
Resolved - CDP destinations and Session Replay are now caught up. thanks for your patience
Jul 3, 10:00 UTC
Update - We're continuing to catch up with ingestion processing. Some teams will already be seeing recording data back at realtime, we expect to full catch up with session replay data in around an hour
Jul 3, 07:47 UTC
Monitoring - Earlier there was an outage due to an external provider. See https://status.posthog.com/incidents/f54ty14b48wx

We've identified that not all internal systems recovered from that outage. Meaning that session recordings were being ingested but were not available for playback and CDP destinations were not being triggered

We've resolved that and all systems are now processing. Session replay and CDP will catch up.

Jul 3, 02:02 UTC
Monitoring - Looks like warpstream is coming back, and so are we. Monitoring the situation.
Jul 3, 01:46 UTC
Investigating - Looks related to the Warpstream outage in us-east-1 due to dynamoDB downtime in us-east-1
