Previous incidents

We've identified and resolved the intermittent request failures that occurred earlier. The issue was caused by elevated traffic spikes overwhelming our reverse proxy, which temporarily prevented some requests from reaching our backend servers. We've implemented improved rate limiting and traffic management on our proxy layer to prevent this from occurring in the future. All systems are now operating normally.

We just published a Post-mortem Post here :

Between 2:00 PM and 3:00 PM UTC, we detected instability in our production environment.
To prevent inconsistent results on persons endpoints, we temporarily placed the API in maintenance mode for one hour.

The production environment is now fully stabilized, and our team continues to closely monitor the situation.

We experienced a production outage caused by an issue with one of our hosting provider, impacting all services from 08:00 UTC to 09:10 UTC.

Our team immediately contacted the provider, restarted all services, and redeployed the full production environment. Once the redeployment was completed, all systems returned to normal and have been fully stable since.

Between 16:57 and 17:31 CEST on 2025-10-03, our services were down because of a migration-relation job which crashed our whole production. Roll-back successful within 30min and fully live again.
