Partial System outage

Incident Report for OutSystems

Postmortem

Users in the Asia-Pacific region experienced login issues with the ODC Portal and Studio, which temporarily disrupted access. The issue was identified through both customer reports and internal monitoring and was traced to performance problems within the system’s internal messaging component.
Initial recovery involved restarting services in affected regions, which restored access for users. Further investigation revealed that one of the background components had a faulty instance, and a full service restart was required to stabilize performance.
A follow-up issue occurred the next day, again impacting login functionality. This time, analysis showed that the problem was not due to network issues, but to the way the system handled message compression and memory usage. A temporary fix was applied, significantly reducing memory consumption and resolving the performance degradation.
The root cause has been confirmed as inefficiencies in the internal messaging layer, which handles coordination across regions. A deeper investigation is ongoing, and preventive measures are being implemented to avoid similar incidents in the future.
