May 22, 2025
Resolved - This incident has been resolved.
May 22, 19:59 UTC
Monitoring - We identified the issue and the ingestion pipeline is catching up.
May 22, 18:58 UTC
Investigating - Our data processing infrastructure is running behind which is causing inaccuracies in the reporting tools. No data has been lost.
May 22, 18:20 UTC
May 21, 2025
Completed - The scheduled maintenance has been completed.
May 21, 12:42 UTC
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
May 21, 10:45 UTC
Scheduled - We are performing scheduled maintenance on our EU Cloud Clickhouse database. We don't expect significant disruption but there may be some slow queries or ingestion delays.

Resolved - Parts are back to normal and the cluster is responding normally again.

We'll keep monitoring it and let you know if we find misbehavior again.

May 17, 10:32 UTC
Investigating - We are currently investigating increased parts counts on our datastore and we are investigating why these parts are not being merged as they should. This will cause increased query times.
May 17, 06:38 UTC
May 16, 2025
Resolved - We've caught up on our backlog of messages. Ingestion rates look optimal. Parts are being merged as they should. New nodes are fully online. Query latencies are looking great at 100ms avg. Should be smooth sailing from here on out. Enjoy your Friday!
May 16, 19:18 UTC
Monitoring - There were some recurring errors in our infrastructure that led us to restart clickhouse nodes.

We are falling behind on events ingestion, as we are replacing some nodes in our ClickHouse cluster. This will increase lag in our ingestion pipeline.
Performance may be impacted during this time too. We are still working on this and monitoring it.

May 15, 21:26 UTC
May 15, 2025
Resolved - We've resolved the incident. This just affected querying and no data was lost

We're still working on finding the root cause for this issue (our clickhouse nodes were segfaulting without warning) and will continue to monitor.

May 15, 16:00 UTC
Update - We're experiencing failures to load data across the entire app at the moment. We've identified the root cause and are working to resolve this asap.

Resolved - Lag has recovered and the system is completely functional again.

Sorry for any inconvenience caused by this incident.

May 13, 07:03 UTC
Monitoring - The cluster is now responsive and the data ingestion has been resumed. The app is responding better now.

We are still monitoring a couple of fixes we have pushed. We identified a query that was flooding the cluster and which may have been the root cause of this.

May 12, 21:56 UTC
Update - We have recovered a good part of the cluster, but we are still working to bring it back completely.

The performance may be still degraded. We think some problematic queries may have been the root cause, we are still investigating it.

May 12, 21:10 UTC
Update - We are trying to bring back the cluster.

The app may be completely unresponsive, and lag is expected during this time, we'll try to provide an update as soon as possible.

May 12, 20:05 UTC
Investigating - We have detected a partial outage in our ClickHouse cluster and it's impacting the application response and performance getting insights.

We are investigating the root cause.
