CME says email outage caused by Salesforce service disruption

The notable point is the source of the failure: a derivatives exchange's own email system went down because of a third-party cloud provider, not internal infrastructure. That is a reminder of how much operational risk at major market venues now sits outside their direct control, and it lands at a time when cloud concentration is already a live concern for regulators and market participants. CME gave no restoration timeline, so whether this stays a contained email issue or prompts closer scrutiny of vendor dependency is the open question.
