   This incident has been resolved. Incident Duration: April 21, 2026, 1:40 PM– April 23, 2026 11:00 AM PT Impact Summary: During this window, customers using Microsoft Office365 were unable to retrieve interviewer availability or schedule interviews. Existing data was not lost, but new scheduling actions failed until service was restored. Cause: An internal encryption key rotation was completed for several services, but a related dependency used by the calendar service was not updated. As a result, the calendar service was unable to read newly issued Microsoft access tokens, causing scheduling requests to fail for Office365-connected accounts. Mitigation: The calendar service was updated to use the correct dependency compatible with the new encryption keys. Once deployed, scheduling functionality was fully restored and verified in production. An RCA will be provided within 7-10 business days if applicable.
