If you have a BungeeCord network then you might want to consider this plugin, it sends a message to all the servers connected to the bungeecord to check if they're offline.

If a server is offline and comes online it will send all players with a specific permission a message and if it is online and goes offline it will send all players with a specific permission a message.

You can also do /serverlist to show all servers alphabetically, along with the message you set to show in the config

Mostly everything is editable in this plugin below is the config.yml with all the comments and stuff so you can know what is what

Feel free to tell me any suggestions for what I should add

Features to come: None right now, Please suggest features you think I should add

EDIT: Added the server change event and messages when the server goes offline or comes online

For anyone wanting to use the server status event in their code this is what it would look like
Code (Text):
@EventHandler
    public void serverChangeStatus(ServerStatusChangeEvent e) {
        if (e.isOnline()) {
            // Server went online
        } else {
            // Server went offline
        }
    }
