Elevated API Errors
Resolved - We identified undetected underprovisioning in one of our network components.

We scaled this up now and working on a fix to mitigate this long-term.

Thank you for your patience.
Apr 25, 11:03 UTC
Update - Performance and error rate are back to normal levels.

we're still investigating the root cause for this issue.
Apr 25, 09:45 UTC
Update - We are continuing to investigate this issue.

Notice about US: this incident never affected the US environment. The "partial outage" status was wrong for that. We will correct this later. apologies for the inconvencience
Apr 25, 09:32 UTC
Update - The error rate has gone down, we're still looking for the root cause.
Apr 25, 09:28 UTC
Investigating - Elevated error rates are coming up again, we're investigating
Apr 25, 08:52 UTC
Monitoring - We identified a surge in memory usage and workload eviction events. We scaled up feature flags and web app to mitigate.

We're monitoring this.
Apr 25, 08:20 UTC
Update - Situation has calmed down after scaling up resources. We're still investigating the root cause.

Notice: in an earlier message, it was reported that this was about the US region. This was wrong, this is only about the EU region. Apologies for the initial wrong reporting
Apr 25, 08:12 UTC
Update - We are continuing to investigate this issue.
Apr 25, 08:03 UTC
Investigating - We're experiencing an elevated level of API errors incl feature flags and are currently looking into the issue.

Data Processing Delays - Reporting Tools Affected
Resolved - This incident has been resolved.
Apr 23, 02:06 UTC
Monitoring - We're monitoring the ingestion pipeline, as it processes the delayed messages. We're estimating that the system will fully recover within an hour.
Apr 23, 00:01 UTC
Update - We are still investigating intermittent latency spikes in the event ingestion pipeline. Events are still being processed with a delay, which should decrease over time.
Apr 22, 21:53 UTC
Update - We are still investigating the root cause of the issue. Events are still delayed but the delay is no longer increasing. We hope to have a resolution shortly
Apr 22, 15:26 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 shortly.

API Query endpoint intermittently 500'ing
Resolved - This incident was resolved over the weekend.
Apr 22, 08:50 UTC
Monitoring - We've shed load and haven't seen errors re-occur yet. We'll continue monitoring this over the weekend.
Apr 17, 22:59 UTC
Investigating - The API query endpoint is throwing intermittent 500 errors due to capacity limits on our end. We are working to fix this on our end and make the errors more clear.
If known valid queries are failing with 500s, we recommend retrying queries with exponential backoff.

US Error Tracking Processing Delays
Resolved - Bug fixed, ingestion workers scaled back up and lag recovering rapidly. No data loss should be observable.
Apr 18, 11:05 UTC
Monitoring - We've identified the root cause of the issue. We are reprocessing exception events and continuing to monitor to make sure the pipeline fully recovers.
Apr 18, 11:02 UTC
Identified - We are currently experiencing downtime in our error tracking data pipeline, while a bug is resolved. No data loss has occurred.

Processing Delays
Resolved - We've resolved the issue and ingestion has caught up to real time
Apr 12, 17:06 UTC

Apr 12, 15:15 UTC
Investigating - Our EU data processing infrastructure is running behind, which is causing inaccuracies in the reporting tools. No data has been lost, and the system should catch up shortly. We're monitoring it closely.
