Error
Random errors while browsing Wikimedia Commons related to overloaded databases. I got errors on at least cluster27 and cluster31 in the error messages I got:
Désolé ! Ce site rencontre des difficultés techniques.
Essayez d’attendre quelques minutes avant de charger à nouveau.
(Accès à la base de données impossible : Cannot access the database: Database servers in cluster27 are overloaded. In order to protect application servers, the circuit breaking to databases of this section have been activated. Please try again a few seconds.)
