    We sincerely apologize for any impact this incident has caused to you, your business, or your customers. At Okta, trust and transparency are our top priorities. Outlined below is the RCA summary for a recent incident where a third-party provider or downstream service experienced an issue that impacted the Okta service. We are committed to implementing improvements to the service to prevent similar occurrences. Detection and Impact: Okta detected an increase in customer support tickets regarding email delivery issues. Customers using custom email domains routed through Proofpoint experienced email delivery deferrals. During this period, affected end users were unable to receive system-generated emails, including One-Time Passwords (OTPs), account activation emails, password reset emails, factor enrollment emails, and other automated notifications. Root Cause Summary: Third-party provider Proofpoint experienced a service disruption, causing issues with email deliverability. When Okta services attempted to send emails to recipient domains whose MX records pointed to Proofpoint’s infrastructure, the delivery attempts failed due to connection errors, resulting in deferred delivery. Okta’s email sending infrastructure operated normally throughout the event. Remediation Steps: Okta Engineering monitored service telemetry and confirmed that email delivery returned to normal pre-incident baselines once Proofpoint restored stability to its infrastructure. Preventive Actions: Okta is defining automated alerting thresholds for email-bound and deferral rates to decrease detection time and updating runbooks to allow faster diagnosis of downstream provider disruptions. Timing: Incident start: August 14, 2026, at 5:00 AM PDT Incident resolved: August 14, 2026, at 10:04 AM PDT.
