On July 30, 2026, between 15:19 and 15:59 UTC, customers in multiple regions experienced an outage affecting access to the OutSystems ODC Portal, preventing them from logging in or accessing their development environments. The incident was caused by the addition of a custom header, which prevented requests from reaching the portal. Following the code change rollback, service was restored by 15:59 UTC. To prevent similar incidents in the future, we are implementing additional automated testing to validate configuration changes before they are deployed to production and conducting a comprehensive review of our code review and testing procedures to catch such issues earlier in the development process. We appreciate your patience during this incident and apologize for any disruption to your work.
