update2025-10-23 18:38 UTC
As of 17:42 UTC, Salesforce core app services have been restored, and customers are no longer impacted. We identified that a message request was contributing to high traffic and overwhelming system capacity, causing intermittent service disruptions. We implemented an immediate fix by suspending the message request that was contributing to the capacity constraints. We apologize for how this incident affected you and your business. We will undertake a full investigation of the incident, establishing the technical trigger, the underlying cause, and preventive action to avoid a repeat in the future.
