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.

US: Elevated error rate in session replay ingestion
Resolved - our services are all back - as this was a major outage, we will analyze the concrete root causes and impact of this and come back with the results. Apologies for the disruption.
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

US: Delayed data processing due to patching event
Resolved - Patching is done and we processed the data.

Thank you for your patience.
Jul 2, 14:45 UTC
Monitoring - Due to a security patching event in our event processing infrastructure, data processing is delayed.

We're monitoring and will update once this is over.

No data will be lost during this operation.

EU - elevated error rate for feature flags, increased latency
Resolved - This incident has been resolved.
Jun 25, 15:23 UTC
Update - we're monitoring the systems after fixes were applied and they are stable.

We're processing the delayed data which should be completed soon.

Web app and feature flags are fully operational again for a while now.

We update this once the delayed data is fully processed.
Jun 25, 13:59 UTC
Monitoring - We applied some more fixes and seeing signs of recovery. We're monitoring the situation.

We still need some time to crunch through the data. We will send an update.

No data has been lost in all of this.
Jun 25, 12:09 UTC
Identified - We identified the cause for the increased latency. The error rates for feature flags have decreased (from 1.5%) and the ingestion lag is coming down.
Jun 25, 11:49 UTC
Update - We're investigating increased error rates in feature flags and an increase in latency in the ingestion pipeline.

There is no data loss, but we're currently processing events with a delay.
Jun 25, 09:30 UTC
Update - We're still investigating but also discovered that the web app is showing increased latency.
Jun 25, 08:27 UTC
Investigating - We've spotted elevated error rates in feature flags. We're currently investigating the issue, and will provide an update soon.
