If google CDN is down, or any other CDN you rely on, you can switch back to the local version of jQuery and jQuery UI to keep your SeoToaster running.
First, you find the local copy of jquery here:
/system/js/external/jquery/jquery.js
and
system/js/external/jquery/jquery-ui.js
This is only by reference, in case you want to change the local file.
To make the switch, open your application.ini file; you find it in:
/seotoaster_core/application/configs/
In 'jquery' and 'jquery ui' change the value from 'cdn' to 'local'
