EU: feature flags and surveys with elevated error rates
Resolved - EU: We were observing increased error rates for feature flags and surveys.

While mitigating first issues with feature flags, we were restarting some internal components, which caused other issues.

Surveys showed elevated error rates between ~15:22 UTC and 15:36 UTC.
Feature flags showed elevated error rates between ~15:00 UTC and 15:36 UTC.

There was a large number of timeouts in our database in the EU region causing high feature flags error rate and service disruptions.

Apologies for this disruption.

US: Increased person processing load is causing locks on the replica DB
Resolved - This incident has been resolved.
Mar 24, 09:50 UTC
Monitoring - We scaled up the processing to ease out the spike. We are monitoring the situation.
Mar 21, 23:56 UTC
Identified - Performance on the posthog read replica database is a bit degraded due to a high load of person ingestion processing. This is occasionally affecting flag evaluation since the feature flag service depends on the read replica database

EU: Data Processing Delays - Reporting Tools Affected
Resolved - Issue resolved
Mar 20, 07:16 UTC
Identified - We have identified an issue with our service that builds the list of event and properties to search for when querying data.

We are deploying a fix now and hope to see recovery in the coming hours. Until then UI tools for querying your data may be missing information you would expect.

No data loss has occurred and event ingestion itself is unaffected.

Taxonomy updates delayed in EU
Resolved - Issue resolved
Mar 19, 08:19 UTC
Monitoring - The issue is resolved, and we are catching up on newly seen events and properties.
Mar 13, 17:43 UTC
Identified - Our taxonomy generation system (for event and property definitions you use in filters and elsewhere) is currently delayed as we fix a minor schema bug. This means new event names or properties you just sent to posthog won't be available for use in places like filters or insights. We have identified the bug, and expect to resolve it shortly.
Mar 13, 10:41 UTC
PostHog Cloud UI in EU is down
Resolved - Systems were stable over the last few hours, metrics are showing normal behaviour over longer time for both flag evalulation and the web UI.

Thank you for you patience!
Mar 19, 08:11 UTC
Monitoring - Flag evaluation is back to normal, monitoring the overall state
Mar 18, 23:28 UTC
Update - Cloud UI is back up, investigating impact on flag evaluation
Mar 18, 23:24 UTC
Investigating - We've spotted that something has gone wrong. We're currently investigating the issue, and will provide an update soon.

PostHog app in EU is not loading
Resolved - We've spotted that something has gone wrong. We're currently investigating the issue, and will provide an update soon.
Mar 13, 00:19 UTC
Identified - PostHog cloud is unavailable, the surveys API and local_evaluation APIs are also affected. Fix is being worked on at the moment.
Mar 13, 00:03 UTC
Investigating - We're experience issues loading the PostHog app in EU. Data ingress does not appear to be affected.

US app has intermittent errors
Resolved - We'd identified a migration that had unintended impact to our database. We've cleared the lock and watching db health stabilize. All is looking back to normal at this time.
Mar 12, 19:11 UTC
Investigating - We're seeing intermittent errors with loading us.posthog.com, and we're investigating why.

This isn't impacting the ingestion of data.
