Salesforce experienced a feature disruption affecting multiple instances across 20 components, where customers encountered "Fatal Error Unknown Exception" messages when attempting to perform deployments. The incident lasted 29 minutes and impacted components across CS, EU, and NA regions. The Salesforce Technology team investigated multiple paths to isolate the cause and implement a fix to restore services.
Upon further investigation, the Salesforce Technology team has determined that the start time of impact is different than initially understood. We have now 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.
