Attention une mise à jour du service Gitlab va être effectuée le mardi 18 janvier (et non lundi 17 comme annoncé précédemment) entre 18h00 et 18h30. Cette mise à jour va générer une interruption du service dont nous ne maîtrisons pas complètement la durée mais qui ne devrait pas excéder quelques minutes.
