Hello,
On Tuesday, Dec 16, 2025, at 3:45pm EST / 9:45pm CET we will be upgrading the Elasticsearch cluster from version 8.14.3 to 9.2.2 for Crash Stats (
https://crash-stats.mozilla.org/). There should be no downtime. This process is expected to take less than 10 minutes, but it may take up to two hours.
For more details, please see
https://mozilla-hub.atlassian.net/browse/CRINGE-75.
Please reach out to the Crash Ingestion team (just @bdanforth at the moment) in the #crashreporting Matrix channel if you have any questions or concerns, or if after this date, you experience any incorrect search results or 500 errors.
Sincerely,
Bianca Danforth and the Crash Ingestion team
