Historique des incidents

An unexpected failure of network interfaces occurred on our main server, resulting in extended outages. We have now restored operations. There are still performance issues in some areas, which we are working on resolving. Such repeated outages are very stressful for us. Therefore, we are now massively expanding our infrastructure and converting it to a highly available cluster environment. We will keep you regularly updated on the progress of this upgrade so that you are always aware of the measures we are taking to prevent similar problems in the future.
