In order to gain performance, we will update our MySQL storage from Wednesday 11th to Friday 12th.

This can cause loss of performance during the operation.

===

Afin d'améliorer les performances, nous allons mettre à jour le stockage de nos serveurs de bases de données dans la nuit de mercredi 11 au jeudi 12.

Cette mise à jour peut entrainer des baisses de performances sur nos serveurs MySQL.
