 * I’m trying to setup HyperDB for failover if one DB server goes offline.
 * I have 2 servers defined:
 * $wpdb->add_database(array( ‘Host’, ‘User’,’Password’ , ‘Database’));
    $wpdb->
   add_database(array( ‘Host2’, ‘User’,’Password’ , ‘Database’));
 * (If my syntax is wrong, please tell me)
 * I keep getting this error:
 * “Unable to connect to :3306 to read table ‘wp_users’ (global)”
 * Any suggestions?
 * Thanks!

 * I suspect the access rights for your users are not set correctly. Specifically
   check to see if they are set to allow remote connections (ie. not localhost or
   127.0.0.1)
