Link to articles don't work? Does it work with Multisite?

Yep the plugin works on Multisite. WP-Cron on Multisite works just as it does on individual sites (there’s no network-wide WP-Cron system). Activate it on your root site and then visit Tools -> Crontrol.

Okay, so my understanding is that each site on the network runs things like checking for plugin updates, etc. Can I use this to disable it on say all but one of the sites? And if so, would I have to go through and disable it on each one manually?

And what if I’ve disabled WP-Cron (I had to on one site, it was killing my VPS)? Does it still work normally when I run wp-cron via a real cron job?
