Here’s a custom maintenance page template code for WordPress that will increase the experience of your site visitors while you’re doing some maintenance work in the backend.
This page is automatically displayed, replacing the default “Briefly Unavailable for Scheduled Maintenance” message, when WordPress or WordPress plugins are upgrading.
<?php
/* Tell search engines that the site is temporarily unavilable */
$protocol = $_SERVER["SERVER_PROTOCOL"];
if ( 'HTTP/1.1' != $protocol && 'HTTP/1.0' != $protocol ) $protocol = 'HTTP/1.0';
header( "$protocol 503 Service Unavailable", true, 503 );
header( 'Content-Type: text/html; charset=utf-8' );
header( 'Retry-After: 600' ); // 10 minutes
?>

<?php die(); // Pass control back to WordPress upgrade routine ?>How to Use?
Just create a new file named maintenance.php inside wp-content directory and paste in the above code in it. maintenance.php is kept as an independent file in the WordPress installation, so it’s not affected by core upgrades. [via Aliso]
