Session Replay - Recordings Delayed
Resolved - Our ingestion service has caught up and all recordings are now available in the app
Nov 7, 11:00 UTC
Identified - Our team has identified the root cause of the session recording lag. No data has been lost and we are working on a fix so that recent recordings should be available shortly
Nov 7, 10:44 UTC
Investigating - Our team are investigating why some teams are not seeing session recordings for the past 15 hours.
Nov 7, 10:16 UTC
Elevated API Errors
Resolved - The service impact is resolved
Nov 7, 06:28 UTC
Monitoring - Session Recordings capture service has recovered and operators are monitoring it
Nov 7, 05:44 UTC
Investigating - The success rate of capturing session recording events is degraded. Operators are investigating the cause
Nov 7, 05:00 UTC
Elevated API Errors
Resolved - We think the impact from the issue is over.
Nov 7, 00:06 UTC
Monitoring - We identified networking issues in session replay data capture and applied fixes.

The elevated error rate has gone down and we're monitoring
Nov 6, 21:44 UTC
Update - We've spotted that something has gone wrong. We're currently investigating the issue, and will provide an update soon.
Nov 6, 20:10 UTC
Investigating - We're experiencing an elevated level of API errors regarding session replays and are currently looking into the issue.

Session replay buffering
Resolved - The endless buffering issue affecting some longer session replays appears to be resolved. Longer recordings may still take a bit more time to buffer, but they should now load as expected.
Oct 30, 14:50 UTC
Monitoring - A fix for the endless buffering issue on longer session replays has been deployed, and we’re monitoring the results.
Oct 30, 13:57 UTC
Investigating - We’re aware that a number of users are experiencing much longer buffering times when viewing extended session replay recordings.
Oct 30, 11:27 UTC
Elevated Errors and Latency Feature Flags US
Resolved - We were experiencing connectivity issues on our feature flags nodes due to resource exhaustion on those nodes. After identifying this bottleneck, we applied changes that resolved this resource exhaustion and the service recovered.
Oct 30, 11:10 UTC
Identified - We've rolled back some recent caching changes and have observed latency dropping to more appropriate levels but continue to look at improving this further.
Oct 30, 06:10 UTC
Investigating - We're looking into increased error rates and latency on the feature flags service in US. We rolled back some hardware changes for the service and the errors have mostly subsided. We're still looking into increased latencies currently.

Oct 29, 2025
Billing section inaccessible
Resolved - The issue has been fully resolved. The Billing section and the Billing API should now be accessible without any issues. We will continue to monitor to ensure everything remains stable.
Oct 29, 17:13 UTC
Monitoring - We have identified and resolved the heavy load affecting our workers caused by an internal process. Systems have returned to normal and are operating as expected. We are continuing to monitor to ensure the issue is fully resolved.
Oct 29, 16:54 UTC
Investigating - The Billing section is intermittently timing out, making it inaccessible for some users. We are actively working on resolving the issue. This incident also affects our Billing API, which is used to submit tickets, meaning some customers may be unable to create support tickets through our platform.
