## Timeline of updates

- **update** 2026-08-21 11:12 UTC: We're investigating an issue affecting some customers using chatbots or custom agents connected through the Salesforce Platform Model Context Protocol (MCP) Server. Customers are experiencing errors when their agent tries to query or update data in a Salesforce org.  Initial investigations indicate a recent release as the likely trigger. We're planning to roll back to the last known good version.  We'll provide an update in 30 minutes or sooner if additional information becomes available.
- **update** 2026-08-21 11:30 UTC: We're rolling back the change that was identified as the likely trigger. Initial results confirm that connections are succeeding‌. We’re monitoring the progress of the rollback to full completion before confirming resolution.  We'll provide an update in 30 minutes or sooner if additional information becomes available.
- **update** 2026-08-21 11:35 UTC: Upon further investigation, we've determined that the start time of impact is different than initially understood. We've revised the start time of the Trust post to more accurately reflect the time customers may have begun to experience impact. We apologize for any confusion caused by this.
- **update** 2026-08-21 11:54 UTC: Rollback has been completed and customers using chatbots, custom agents, or Salesforce agents connecting through the Salesforce MCP Server, are no longer experiencing errors when their agent tries to query or update data in a Salesforce org.  We'll perform a full investigation of the incident, confirming the technical trigger, the underlying cause, and preventive action to avoid a repeat in the future. We apologize for how you and your business may have been affected by this incident.
