If you, like me have woken up to all your wpultimo wordpress multisites running super super slow, then keep reading as I’ve got a fix for you.
[wpultimo.com](http://wpultimo.com) is currently down, as is a few associated sites.Upon further digging, it appears the wp-ultimo wordpress plugin is constantly trying to reach [wpultimo.com](http://wpultimo.com) and this is causing a huge slowdown of the plugin (Definitely something for the developers to fix ASAP)
**The Solution?**
I needed to get my sites up and running ASAP, so the best solution I’ve found so far is to temporarily add the following to your wp-config file.
`define( ‘WP_HTTP_BLOCK_EXTERNAL’, true );`
This fixed it in an instant.
Feel free to add any other suggestions or fixes to get things up and running.
Hope this helps.

Add the following to your `wp-config.php` file to block external requests and allow specific hosts:
define(‘WP_HTTP_BLOCK_EXTERNAL’, true);
define(‘WP_ACCESSIBLE_HOSTS’, ‘api.wordpress.org,*.example.com’);
Replace `*.example.com` with any other necessary hosts.
