Everything Google has been blocked in China. My site hangs

Everything Google has been blocked in China. My site hangs while trying to resolve the google fonts.

How can I remove the google fonts from the Network theme? In the options there is Fonts section, which says, "We include google fonts directory fonts you can view here", If I knew which fonts were not google fonts, would chosing them fix this issue?

Or do I need to alter the theme?

Is there a way to remove google fonts for all sites and sub sites?

Thanks,

Matt
