After an advanced investigation by our team, we have been able to determine what was the cause of this outage in the Shona database.
Our accommodation notified us several days in advance requesting a forced migration due to stability problems in said VM and, for some reason, this email was ignored by us.
After continuing to monitor the database in the background, we have been able to verify that the stability was automatically resolved by our hosting, but, due to the forced migration they did, the database could never recover from its frozen state.
