(All Times US/Pacific) Incident Start: 25 June, 2024 11:58 Incident End: 28 June, 2024 12:22 Duration: 3 Days, 23 minutes Affected Services and Features: Google SecOps Regions/Zones: US - Multi-Region Description: Google SecOps experienced service degradation with multiple features in the US/multiregion for a duration of 3 days and 23 minutes. Customer Impact: During the incident some customers would have experienced the following issues within Google SecOps: Parser UI: Affected users would have been unable to access parsers via the user interface. Feeds UI: Functionality was degraded, preventing feed names from being displayed in the user interface. Raw Log Search Timestamp Selector: The timestamp selector prevented affected users from selecting earlier dates, thus limiting search functionality. Raw Log Search UI: The raw log search UI displayed all log types as 0kB, hindering accurate log analysis. Raw Log Search Historic Availability: Raw log search for historic data beyond 48hrs after ingestion was unavailable. IOC matches page: Feed Source Names were not shown correctly. Data ingestion: Ingestion was delayed for some 3rd party API feeds.

The issue with Chronicle Security has been mitigated for all affected users as of Friday, 2024-06-28 11:00AM US/Pacific. Parser UI: The parser UI functionality is working as expected. Feeds UI: The feeds UI functionality is working as expected. Raw Log Search Timestamp Selector Malfunction: Mitigated and fixed. Raw Log Search UI Display Error: Mitigated and fixed.
