Ubuntu 14.04, MariaDB 10.1, Zabbix 3.0.3 from repo.zabbix.com
After visiting our Zabbix dashboard it mentioned that "the information may not be accurate because Zabbix-server is not running".
During an upgrade of MariaDB the mysql-server process was shut down and as a result all Zabbix-server intances died in the process.
The downtime was less than a minute, it seems like zabbix-server simply exited without retrying.

This should not be desirable behavior as Zabbix-server should retry connecting to the MySQL-server whenever it is unable to do so as it is likely a temporary issue.
