No incidents reported today.

Dec 6, 2024
Data Processing Delays - Reporting Tools Affected
Resolved - We are back up to date and queries are running at normal speeds. Enjoy your Friday!
Dec 6, 20:38 UTC
Identified - Our data processing infrastructure is running behind which is causing delays in the reporting tools. No data has been lost and the system should be caught up shortly.

You may also notice slower than normal querying.

EU ingestion lag and degraded performance
Resolved - The problem was identified and everything is back to normal. We had a period of lots of queries hitting ClickHouse in a loop. Once it was stopped, the cluster recovered properly.
Nov 29, 16:33 UTC
Investigating - The EU ClickHouse is going under heavy load and is causing ingestion lag and degraded performance on queries.

We are investigating what can be the root cause.

Nov 28, 2024
Data Processing Delays - Legacy Webhooks
Resolved - An upstream service (cymbal) adopted a compression scheme not supported by the legacy webhooks and onevent consumers (due to their reliance on kafkajs). The fix deployed was to add support for the compression scheme (LZ4) to kafkajs, using another 3rd party library. All systems have now fully caught up to the real-time data stream.
Nov 28, 09:28 UTC
Update - Issue resolved, all systems now recovering.
Nov 27, 17:49 UTC
Update - Our legacy webhook processing infrastructure is running behind because of an bad configuration change. Note that this is not affecting CDP based webhooks in any way. No data has been lost and the system should be caught up shortly.
Nov 27, 13:31 UTC
Update - Our webhook and legacy plugins processing infrastructure is running behind because of an bad configuration change. Note that this is not affecting CDP in any way. No data has been lost and the system should be caught up shortly.
Nov 27, 13:15 UTC
Identified - Our webhook infrastructure is running behind because of a bad configuration change. No data has been lost and the system should be caught up shortly.

Storage engine upgrade
Resolved - We have completed our storage system upgrades. There will be some elevated query errors here and there, but for the most part we are back and operating nominally.
Nov 26, 08:06 UTC
Monitoring - We are upgrading our core data storage engine. While this happens some insights may error out temporarily. We don't expect this to last more than an hour.

Replay ingestion delayed in US
Resolved - We've caught up entirely now, thanks again for your patience
Nov 25, 19:59 UTC
Update - We are mostly caught up and monitoring continued recovery. Thanks again for your patience!
Nov 25, 15:58 UTC
Monitoring - We've identified the issue and scaled our infrastructure to start to process the lag, thanks for your patience!
Nov 25, 09:50 UTC
Investigating - We've spotted that ingestion of session recordings has fallen behind and we're looking into it now
