There is currently an incident, and database servers 11, 22 and 23 stopped responding. Instances using those servers are down. I apologize for the disruption. I'm trying to gather more information and will update as soon as I know more.
OK, the problem has been identified in the data center: https://bare-metal-servers.status-ovhcloud.com/incidents/dgksqhl6lswj

Database server 23 is responding again.
Database servers 11 and 22 still down.
Database server 11 is now also back online. Only database 22 still down.

Latest update from OVH:
"All services in room GRA0404 are now available again.
We are actively working to restore the servers in room GRA0406." - https://bare-metal-servers.status-ovhcloud.com/incidents/dgksqhl6lswj

Hopefully, the database server 22 should be back online soon.

Really sorry for the long downtime.
