Multiple customers in EU, US, DE, UK and CH regions were not able use Collections across Diagrams, Reports and Dashboards. Service degradation lasted from Jan 17, 2025 09:25 UTC to Jan 17, 2025 09:52 UTC (27 mins). There was no data loss.
We reverted changes that caused the issue. It was resolved at Jan 17, 2025 09:52 UTC.
We introduced a new feature to navigation item search API endpoint. Even though we had tests in place, one of the cases was not covered and caused an issue when a specific parameter was included in the API request.
We will extend our testing strategy by including additional test types and canary releases to prevent similar regressions in the future.
